Performance Evaluation of Different Mobile Ad-hoc Network Routing Protocols in Difficult Situations

Performance evaluation of Mobile Ad-hoc Network (MANET) routing protocols is essential for selecting the appropriate protocol for the network. Many routing protocols and different simulation tools were proposed to address this task. This paper will introduce an overview of MANETs routing protocols as well as evaluate MANET performance by using three reactive protocols—Dynamic Source Routing (DSR), Ad-Hoc On-demand Distance Vector (AODV), and Dynamic MANET On-Demand (DYMO)—in three different scenarios. These scenarios are designed carefully to mimic real situations by using OMNET++. The first scenario evaluates the performance when the number of nodes increases. In the second scenario, the performance of the network will be evaluated in the presence of obstacles. In the third scenario, a group of nodes will be suddenly shut down during the communication. The network evaluation is carried out in terms of packets received, end-to-end delay, transmission count or routing overhead, throughput, and packet ratio.

Mobility‐Aware Routing Algorithm for Mobile Ad Hoc Networks

Mobile ad hoc network (MANET) is a group of wireless mobile nodes that create a temporary network without the help of any central administration or standard support services. Mobility of nodes determines the overall performance of MANET networks. High mobility of nodes causes frequent changes in the network topology, and this leads to link breakage and increases reinitiating of the route discovery process. MANETs commonly use broadcasting techniques for route discovery process. However, it can cause redundant rebroadcasts, packet collisions, and channel contention. The main objective of this paper is to design and develop the mobility‐aware routing algorithm (MARA) to enhance the performance of the routing protocol in MANETs. The proposed scheme allows mobile nodes to rebroadcast or discard received broadcasted messages. The decision is based on the combination of node speed, distance between nodes, and residual energy of nodes. These parameters are considered both in route request and route reply process to reduce the chance of link breakage and broadcast storm problems. The proposed algorithm has been evaluated based on the performance metrics: packet delivery ratio, average end‐to‐end delay, throughput, and routing overhead. We have used network simulator NS‐2 V‐2.35. The simulation results revealed that MARA outperforms ad hoc on‐demand distance vector (AODV), mobility and direction aware (MAD), and mobility and energy‐aware (MAE) routing protocols.

Mobile adhoc network routing protocols: Performance evaluation & assessment

Mobile Adhoc Networks (MANETs) is a form of wireless networks that lack fixed infrastructure and centralized routers, as opposed to wired networks’ routers or managed wireless networks’ access points. One of the most difficult difficulties with MANETs is routing. The primary goal of routing algorithms is to construct efficient routes between nodes so that messages can be sent on time. Many routing protocols have been created to aid in the routing of MANETs. The aim of this study is to give a study on several popular MANET routing protocols, including OLSR, TORA and AODV. The goal of this study is to analyze MANET's routing protocol performances based on performance metrics such as data packet, overhead, delivery ratio, throughput, and end-point delay using the OPNET simulation program. We model a MANET in which all nodes receive FTP traffic from a single source (FTP server). As a result of this research, the results would also represent a case in which the MANET gets traffic from another network through a similar. According to our findings, OLSR dominated the network with the most routing traffic. TORA is the second, AODV third and DSR is the last. All protocols have a poor packet delivery ratio of up to 59 percent. This degradation is anticipated as a result of massive retransmissions in the network caused by the use of TCP traffic. In terms of throughput and end-to-end latency, OLSR outperforms TORA, DSR and DSR.

Genetic Algorithm Routing Protocol for Mobile Ad Hoc Network

Mobile ad hoc network (MANET) is a dynamically reconfigurable wireless network with time-variable infrastructure. Given that nodes are highly mobile, MANET’s topology often changes. These changes increase the difficulty in finding the routes that the packets use when they are routed. This study proposes an algorithm called genetic algorithm-based location-aided routing (GALAR) to enhance the MANET routing protocol efficiency. The GALAR algorithm maintains an adaptive update of the node location information by adding the transmitting node location information to the routing packet and selecting the transmitting node to carry the packets to their destination. The GALAR was constructed based on a genetic optimization scheme that considers all contributing factors in the delivery behavior using criterion function optimization. Simulation results showed that the GALAR algorithm can make the probability of packet delivery ratio more than 99% with less network overhead. Moreover, GALAR was compared to other algorithms in terms of different network evaluation measures. The GALAR algorithm significantly outperformed the other algorithms that were used in the study.

Performance Analysis of Routing Protocols in Mobile Ad Hoc Networks (MANETs)

Mobile devices are able to build their own networks, which are referred to as mobile ad hoc networks. These networks do not require any kind of permanent wiring or other infrastructure (MANETs). The success of MANETs and their adaptability to a variety of tasks is, to a considerable extent, based on the routing protocols that they use. Using metrics such as routing overhead, end-to-end delay, and packet delivery ratio, we compare and contrast the various routing protocols that can be employed in MANETs, including proactive, reactive, and hybrid protocols. This comparison and contrast is carried out in this study. In addition to this, we discuss the simulation tools that are utilized to evaluate the efficacy of MANET routing algorithms and define the several performance indicators that may be utilizedin the course of this endeavor. This paper makes a contribution to an ongoing body of research into the analysis of routing protocols in MANETs by offering guidance to network engineers and researchers on how to select the most appropriate routing protocol and simulation tool for a particular MANET scenario. In doing so, the paper maximizes the potential for effective and efficient communication between mobile nodes, which is one of the main goals of the research.

Optimized Particle Swarm Optimization Algorithm for the Realization of an Enhanced Energy-Aware Location-Aided Routing Protocol in MANET

Mobile Ad-hoc Network (MANETs) is a wireless network topology with mobile network nodes and movable communication routes. In addition, the network nodes in MANETs are free to either join or leave the network. Typically, routing in MANETs is multi-hop because of the limited communication range of nodes. Then, routing protocols have been developed for MANETs. Among them, energy-aware location-aided routing (EALAR) is an efficient reactive MANET routing protocol that has been recently obtained by integrating particle swarm optimization (PSO) with mutation operation into the conventional LAR protocol. However, the mutation operation (nonuniform) used in EALAR has some drawbacks, which make EALAR provide insufficient exploration, exploitation, and diversity of solutions. Therefore, this study aims to propose to apply the Optimized PSO (OPSO) via adopting a mutation operation (uniform) instead of nonuniform. The OPSO is integrated into the LAR protocol to enhance all critical performance metrics, including packet delivery ratio, energy consumption, overhead, and end-to-end delay.

Efficient Vehicular Ad Hoc Network routing protocol using weighted clustering technique

The Vehicular Ad Hoc Network (VANET) technology is similar to the Mobile Ad Hoc Network (MANET) in operations. But due to high dynamics of vehicles as compare to mobile nodes in MANET, the routing protocols of MANET cannot be applicable for the VANET communications. The high mobility leads the challenges of frequent link breaks and hence poor Quality of Service (QOS) performance. The clustering based routing protocols solves this problems to some extent, however performing the efficient and lightweight clustering and cluster head (CH) selections is still the complex problem for VANETs. The main causes of such problems are related to key parameters such as mobility and geographical distances of vehicles while performing the clustering tasks. In given paper we present a lightweight CH selection and cluster formation by considering mobility and number of neighbors based on geographical distances of the vehicle key parameter at every clustering interval to achieve the stability in network. The superiority of this method is that it is simple and inclusively the part of regular routing operations. For each vehicle the weight is computed to become the CH using mobility and neighbors parameter, hence this method is called as Weight based Clustering for VANET (WCV) routing protocol. The simulation result proves the QOS efficient performance compared to the state-of-art protocols. The WCV protocols improved the overall throughput by 10% as compared to the recent clustering protocol and reduced the delay 7% approximately.

The effect of network size and density to the choice of zone radius in ZRP

<span>Mobile Ad hoc Network (MANET) is a network that consists of several nodes that connect without using a permanent infrastructure. Each node in MANET moves inside and outside of the network freely and randomly. The free and random movements of nodes may cause the topology of the network to change constantly. Therefore, the task of finding routes between nodes is a big challenge. Routing protocols in MANET can be divided into three categories, namely, proactive, reactive and hybrid routing protocols. Hybrid routing protocols such as the Zone Routing Protocol (ZRP) combines the advantages of both proactive and reactive routing protocols by dividing the network area into many overlapping zones. Data transmission to nodes within the zone is done using a proactive routing mechanism, while data transmission to nodes outside the zone is done using a reactive routing mechanism. The zone radius in ZRP determines how much proactive and reactive routing is used, and therefore plays a key role in determining the performance of the network. In this paper, the performance of the ZRP routing protocol is evaluated using the NS2.33 network simulator. The focus of the research is to evaluate the ZRP performance concerning the network size and density to identify an optimum ZRP zone size that will provide good performance. The performance is evaluated by using four performance metrics which are normalized routing load, average end-to-end delay, throughput, and packet delivery fraction. The results show that ZRP produces the best performance when the zone radius size is equal to two hops.</span>

Performance Assessment of QoS Using AODV, TORA and ZRP Routing Protocol in MANET

In Mobile Ad hoc Networks (MANET) nodes often change their location independently where neither fixed nor centralized infrastructure is present. Nodes communicate with each other directly or via intermediate nodes. The advantages of the MANET layout lead to self-structure and compatibility to most important functions such as traffic distribution and load balancing. Whenever the host moves rapidly in the network the topology becomes updated due to which the structure of MANET varies accordingly. In the literature, different routing protocols have been studied and compared by researchers. Still, there are queries regarding the performance of these protocols under different scenarios. MANETs are not based on a predesigned structure. In this paper, the performance assessment of the Quality of Services (QoS) for different protocols such as Ad hoc On-Demand Distance Vector (AODV), Temporally Ordered Routing Algorithm (TORA) and Zone Routing Protocol (ZRP) in the existence of the various number of communicating nodes is studied. The performance matrices throughput, end – to – end delay and packet delivery ratio are considered for simulations. Ns 2.35 simulator is used for carrying out these simulations. Results are compared for AODV, TORA, and ZRP routing protocols. The results show that AODV and TORA perform well in end – to – end delay as compared to zone routing protocol. Zone routing protocol performs well in packet delivery ratio and throughput as compared to both the other protocols.

Detection of Cooperative Black Hole Attack in Wireless Ad Hoc Networks

A mobile ad hoc network (MANET) is a collection of autonomous nodes that communicate with each other by forming a multi-hop radio network and maintaining connections in a decentralized manner. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, reliance on cooperative algorithms, absence of centralized monitoring points, and lack of clear lines of defense. Protecting the network layer of a MANET from malicious attacks is an important and challenging security issue, since most of the routing protocols for MANETs are vulnerable to various types of attacks. Ad hoc on-demand distance vector routing (AODV) is a very popular routing algorithm. However, it is vulnerable to the well-known black hole attack, where a malicious node falsely advertises good paths to a destination node during the route discovery process but drops all packets in the data forwarding phase. This attack becomes more severe when a group of malicious nodes cooperate each other. The proposed mechanism does not apply any cryptographic primitives on the routing messages. Instead, it protects the network by detecting and reacting to malicious activities of the nodes. Simulation results show that the scheme has a significantly high detection rate with moderate network traffic overhead and computation overhead in the nodes.

Physarum-Inspired Autonomous Optimized Routing Protocol for Coal Mine MANET

Mobile Ad Hoc Network (MANET) is suitable for complex environment communication in coal mine. The processes of nutrient flux transfer and path choice in Physarum networks are similar to data transmission and routing decision in MANET. In this paper, we use a Physarum optimization model to design Physarum-inspired autonomous optimized routing (PIAOR) protocol to adapt to the dynamic network topology in underground mine. PIAOR introduces the status of MANET into the Poisson equation in the Physarum model, selects reasonable parameters to represent the transmission performance of the network, and uses the differential evolution equation of the Physarum model to evolve the parameters. PIAOR has achieved the distributed routing decision by automatically reconstructing the optimal routing path, which has reduced the algorithm complexity. Based on NS2, simulation experiments are performed to evaluate the performance of PIAOR, and the results are compared with GPSR, PIMAR, and P-IRP routing algorithms. The experimental results show that the routing path selected by PIAOR is better than that selected by the other three protocols in the performance of average end-to-end delay, delivery ratio, and throughput. The balance of energy consumption and network load is reached, and the network lifetime is effectively prolonged when using the PIAOR protocol.

Performance evaluation of MANET routing protocols based on QoS and energy parameters

Routing selection and supporting Quality of Service (QoS) are fundamental problems in Mobile Ad Hoc Network (MANET). Many different protocols have been proposed in the literature and some performance simulations are made to address this challenging task. This paper discusses the performance evaluation and comparison of two typical routing protocols; Ad Hoc On-Demand Distance Vector (AODV) and Destination-Sequenced Distance-Vector (DSDV) based on measuring the power consumption in network with varing of the QoS parameters. In this paper, we have studied and analyzed the impact of variations in QoS parameter combined with the choice of routing protocol, on network performance. The network performance is measured in terms of average throughput, packet delivery ratio (PDR), average jitter and energy consumption. The simulations are carried out in NS-3. The simulation results show that DSDV and AODV routing protocols are less energy efficient. The main aim of this paper is to highlight the directions for the future design of routing protocol which would be better than the existing ones in terms of energy utilization and delivery ratio.

TAD-HOC Routing Protocol for Efficient VANET and Infrastructure-Oriented Communication Network

Intelligent Transportation System (ITS) is a critical factor for Vehicular Ad hoc Networks (VANET). Even though VANET belongs to the class of Mobile Ad hoc Network (MANET), none of the MANET routing protocol applies to VANET. VANET network is dynamic, due to increased vehicle speed and mobility. Vehicle mobility of VANET affects conventional routing algorithm performance, which deals with the dynamicity of the network node. The evaluation of the existing research stated that Ad hoc On-Demand Distance Vector (AODV) is an effective MANET protocol to adopt network changes for significant resource utilization and also provides effective adaptation in the network change. Due to the effective performance of the AODV protocol, it is considered as an effective routing protocol for VANET. This paper proposed an ad hoc TROPHY (TAD-HOC) routing protocol for the VANET network for increasing efficiency and effective resource utilization of the network. To improve the overall performance, ad hoc network is combined with Trustworthy VANET ROuting with grouP autHentication keYs (TROPHY) protocol. The proposed TAD-HOC protocol transmits data based on time demand in the VANET network with the desired authentication. Results of the proposed approach show the increased performance of the VANET network with packet delay, transmission range, and end-to-end delay. The comparative analysis of the proposed approach with I-AODV, AODV-R, and AODV-L shows that the proposed TAD-HOC exhibited effective performance.

A Survey of State-of-the-Art Energy Efficiency Routing Protocols for MANET

<p class="0papersubtitle">In recent years, the Mobile Ad Hoc Network (MANET) has a vital role in many fields such as healthcare, military, rescue and smart city. Because of its mobility and ad hoc, each mobile network node acts as a router with limited battery energy. The out of energy network node not only affects its own ability to receive/receive packets but also affects the overall performance of the entire network. Therefore, designing an energy-efficient routing protocol will help to optimize the efficiency of MANET. Many routing protocols have been proposing to solve this problem. In this paper, we conducted a survey of the proposed energy-saving routing protocols in the last decade for MANET. Based on the survey results, we propose open research directions. We hope that this work will make a strong motivation in the field of energy-efficient routing research for MANET. The survey results are also a vital basis to serve the in-depth researches in the routing field for MANET of our research team.</p>

Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. Due to the mobility of the nodes in the network, these nodes are self-organizing and self-configuring. Not only they act as hosts, but also, they function as routers. In MANETs, routing protocols are necessary to find specific paths between the source and the destination. The primary goal of any ad-hoc network routing protocol is to meet the challenges of the dynamically changing topology. Therefore, an efficient route between any two nodes with minimum routing overhead and bandwidth consumption should be established. The design of these routing protocols is challenging due to the mobility and the dynamic nature of the mobile ad-hoc networks. MANET routing protocols are categorized into two types: proactive and reactive. In this paper, the MANET characteristics and challenges are highlighted. Moreover, a comparison is conducted between three protocols: namely, DSDV, DSR and AODV in terms of both properties and performance.

MANET Security Appraisal: Challenges, Essentials, Attacks, Countermeasures & Future Directions

Currently, Mobile Ad hoc Networks (MANETs) have evolved as one of the essential next-generation wireless network technologies. MANET comprises of mobile nodes that are self-configurable, and every mobile node behaves as a router for every other node allowing data to move by making use of multi-hop network routes. MANETs signify a networking class that is crucial and differs from conventional systems. Although MANETs are being popularly employed in commercial as well as academic fields, these were primarily designed for deployment in areas like military battlefields, emergency rescue and search operations, and other challenging or hostile environments. The distributed and wireless nature of MANETs paves the way for intruders to reduce MANET functionalities. MANET are susceptible to various attack at different layers since the majority of MANET routing protocols are designed with the assumption that no malicious intruder is present in the network. Therefore, recognizing those threats and finding solutions for their mitigation become essential. This study analyses various security attributes, challenges, attacks on multiple layers and countermeasures for thwarting attacks in MANETs.

An approach for optimal-secure multi-path routing and intrusion detection in MANET

Mobile ad-hoc network (MANET) is dynamic in nature that is susceptible to energy and security constraints. Among most of the existing techniques, energy optimization was a hectic challenge, which is addressed effectively using the routing protocols. Accordingly, this paper proposes an effective multipath routing protocol in MANET based on an optimization algorithm. The energy and the security crisis in the MANET are addressed effectively using the cluster head (CH) selection and intrusion detection strategies namely, fuzzy clustering and fuzzy Naive Bayes (fuzzy NB). Then, the multipath routing progresses using the secure nodes based on the routing protocol, Bird swarm-whale optimization algorithm (BSWOA), which is the integration of bird swarm optimization (BSA) in whale optimization algorithm (WOA). The selection of the optimal routes is based on fitness factors, such as connectivity, energy, trust, and throughput. The analysis of the methods is done using the attacks, such as flooding, blackhole, and selective packet drop based on the performance metrics. The proposed BSWOA acquired the maximal energy, throughput, detection rate, and a minimal delay of 9.48 Joule, 0.676 bps, 69.9%, and 0.00372 ms in the presence of the attack.

Improving mobile ad hoc networks using hybrid IP-Information Centric Networking

Routing protocols for Mobile Ad hoc NETworks (MANETs) constitute a research area with numerous evolved and well-investigated solutions that typically still rely on IP. Although IP-based protocols for MANETs can effectively handle network changes, thus enhancing connectivity while offering scalability, they lack support for advanced communication paradigms, which would enable richer applications and improve network goodput. Information-Centric Networking (ICN) is an inter-networking paradigm that natively supports functions that can enhance the performance of MANETs, such as multicast, multisource communication, and on-path caching. However, ICN raises significant scalability and feasibility concerns in the presence of intense node mobility. In this paper, we propose a hybrid architecture that combines the best of both worlds: it uses IP for maintaining network topology and it relies on ICN for content lookup and dissemination. To this end, we adapt the Named-Data Networking (NDN) ICN architecture to use legacy IP MANET routing protocols, such as Babel. Using a prototype implementation of our design and the Mininet Wi-Fi network emulator, we experimentally investigate the performance of our hybrid design in several scenarios, finding that the data delivery to network traffic ratio is increased up to 250% and 300% compared to pure NDN and IP solutions, respectively.

Different Types of an Energy Efficient Multicast Routing Protocols for QOS in Wireless Communication

This research paper proposes the “mobile ad hoc networks (MANETs) need aid autonomously self-organized networks without framework backing”. For a “mobile ad hoc network, nodes move arbitrarily”; consequently that network might background fast also random topology changes.In view nodes previously, a MANET regularly have set transmission ranges, a percentage node can't correspond specifically with one another.

EPLAODV: Energy Priority and Link Aware Ad-hoc On-demand Distance Vector Routing Protocol for Post-disaster Communication Networks

In Mobile Ad-hoc Networks (MANETs) the major issue between nodes for data transfer is link quality. The majority of the MANET routing protocols try to maintain the link quality between nodes but still need improvement. This paper focuses on link quality between nodes in an ad hoc network in emergency scenarios through the design of the Energy Priority and Link Aware Ad-hoc On Demand Distance Vector (EPLAODV) routing protocol. EPLAODV improves the link quality between nodes through SNR. For performance analysis, the NS2.35 network simulator was used. Simulation time and traffic load were the major simulation parameters. From the simulation results, it is observed that EPLAODV performs better than AODV.
