A Comprehensive Survey of Routing Attacks and Defense Mechanisms in MANETs

Mobile Ad Hoc NETwork (MANET) is the most desired topic of research amidst researchers mainly because of its flexibility and independent nature of network infrastructures. MANET's unique characteristics, like the dynamic behaviour related to network topology, limited bandwidth and battery resources, make routing a challenging task. Currently, several efficient routing protocols based on topology and geographical information have been proposed for MANET. However, most of them assume a trusted and cooperative oriented environment. With the influence of adversaries, the MANET routing protocols are vulnerable to various kinds of attacks. Recently, several research efforts have been made to counter these adversarial activities. This survey investigates the latest and on demand security concerns in MANET. This paper comprehensively discusses the existing attacks in the network layer, various categories of defense mechanisms in the literature, and their benefits and defects when applying to MANET. This paper also classifies the attacks and defense mechanisms based on the routing nature, such as topological and geographical. It also discusses intrusion detection systems as well as anonymous routing in MANETs. Finally, it discusses the challenges and future directions in routing security over the MANET environment.

Efficient Neighbour Feedback Based Trusted Multi Authenticated Node Routing Model for Secure Data Transmission

The Mobile Ad Hoc Network (MANET) is a network that does not have a fixed infrastructure. Migratory routes and related hosts that are connected via wireless networks self-configure it. Routers and hosts are free to wander, and nodes can change the topology fast and unexpectedly. In emergencies, such as natural/human disasters, armed conflicts, and emergencies, the lowest configuration will ensure ad hoc network applicability. Due to the rapidly rising cellular service requirements and deployment demands, mobile ad-hoc networks have been established in numerous places in recent decades. These applications include topics such as environmental surveillance and others. The underlying routing protocol in a given context has a significant impact on the ad hoc network deployment power. To satisfy the needs of the service level and efficiently meet the deployment requirements, developing a practical and secure MANET routing protocol is a critical task. However, owing to the intrinsic characteristics of ad hoc networks, such as frequent topology changes, open wireless media and limited resources, developing a safe routing protocol is difficult. Therefore, it is vital to develop stable and dependable routing protocols for MANET to provide a better packet delivery relationship, fewer delays, and lower overheads. Because the stability of nodes along this trail is variable, the route discovered cannot be trusted. This paper proposes an efficient Neighbour Feedback-based Trusted Multi Authenticated Node (NFbTMAN) Routing Model. The proposed model is compared to traditional models, and the findings reveal that the proposed model is superior in terms of data security.

Comparative Analysis of Intrusion Detection System in Reactive Routing Protocols of Mobile Adhoc Networks

Mobile Nodes in Mobile Adhoc Network (MANET) interact wirelessly with the neighbor nodes without aid ofcentral management. They are subject to a variety of attacks, including as the black hole, insider, grey hole,wormhole, flooding attack, and packet drop, all of which severely impair secure communication. This paperincorporated an intrusion detection system (IDS) into a reactive MANET routing protocol, such as Adhoc OnDemand Distance Vector (AODV), for the detection and prevention of malicious nodes. To make a comparisonwith the implemented IDSAODV, the existing NetSim code of Intrusion Detection System (IDS) based on DynamicSource Routing (DSR) protocol is utilized. We created a Black-hole node to conduct malicious activities in thenetwork. The IDSAODV and IDSDSR are analyzed for different Quality of Service (QoS) characteristics suchas Packet Delivery Ratio (PDR), Throughput, Energy Consumption, and delay in a network size of 10 nodesfor simulation period of 100 seconds. The NetSim tool was utilized as a simulation tool for creating networkwith malicious node and to implement IDS. The results demonstrate that the IDSAODV and IDSDSR efficientlyidentify and prevent a BH attack on the network. The IDSAODV improves PDR and throughput while consumingmore energy and having a little higher delay

A Multipath Cluster-Based Routing Protocol For Mobile Ad Hoc Networks

A MANET (Mobile Ad-hoc Network) is a group of mobile network nodes dynamically forming a network without any pre-existing infrastructure. Multi-path routing protocols in MANETs try to discover and use multiple routes between source and destination nodes. Multipath routing is typically used to reduce average delay, increase transmission reliability, provide load balancing among multiple routes, and improve security and overall QoS (Quality of Service). In this paper, the Cluster-Based Routing Protocol (CBRP), which is a single path MANET protocol is enhanced to use multiple paths. The traffic will be distributed among multiple paths to reduce network traffic congestion and decrease delay. An analytical model is used for multipath and single path CBRP routing protocols in MANETs to estimate the end-to-end delay and queue length. The analytical results show that the average delay and average queue length in multipath CBRP are less than the average delay and queue length in single path CBRP.

Mobile ad hoc network (MANET) proactive and reactive routing protocols

An ad hoc mobile network can be defined as a set of communication hosts that are linked together with no predetermined topology of wireless links and also without the need for a fixed central point. One of the most challenges that occur in this type of networks is the routing. This paper aims to simulate, analyze, evaluate, and make a comparison to the performance of MANET routing protocols AODV and DSDV. Reactive protocols AODV, proactive protocol DSDV with their characteristics are analyzed based on number of parameters metrics such as throughput packets received, delay, jitter-delay, using NS2 simulator. The results from our simulation show that AODV is suitable than DSDV protocol in MANET. This is done according to our simulation throughput results.

An Effective Control of Hello Process for Routing Protocol in MANETs

In the mobile ad hoc network (MANET) update of link connectivity is necessary to refresh the neighbor tables in data transfer. A existing hello process periodically exchanges the link connectivity information, which is not adequate for dynamic topology. Here, slow update of neighbour table entries causes link failures which affect performance parameter as packet drop, maximum delay, energy consumption, and reduced throughput. In the dynamic hello technique, new neighbour nodes and lost neighbour nodes are used to compute link change rate (LCR) and hello-interval/refresh rate (r). Exchange of link connectivity information at a fast rate consumes unnecessary bandwidth and energy. In MANET resource wastage can be controlled by avoiding the re-route discovery, frequent error notification, and local repair in the entire network. We are enhancing the existing hello process, which shows significant improvement in performance.

A Novel Anomaly Behavior Detection Scheme for Mobile Ad Hoc Networks

To sustain the security services in a Mobile Ad Hoc Networks (MANET), applications in terms of confidentially, authentication, integrity, authorization, key management, and abnormal behavior detection/anomaly detection are significant. The implementation of a sophisticated security mechanism requires a large number of network resources that degrade network performance. In addition, routing protocols designed for MANETs should be energy efficient in order to maximize network performance. In line with this view, this work proposes a new hybrid method called the data-driven zone-based routing protocol (DD-ZRP) for resource-constrained MANETs that incorporate anomaly detection schemes for security and energy awareness using Network Simulator 3. Most of the existing schemes use constant threshold values, which leads to false positive issues in the network. DD-ZRP uses a dynamic threshold to detect anomalies in MANETs. The simulation results show an improved detection ratio and performance for DD-ZRP over existing schemes; the method is substantially better than the prevailing protocols with respect to anomaly detection for security enhancement, energy efficiency, and optimization of available resources.

Strong Secure Anonymous Location Based Routing (S2ALBR) method for MANET

Mobile Ad Hoc Networks (MANETs) utilize confounding planning shows that spread community point characters similarly as courses from outside onlookers so as to give obscurity security. MANET contains different little gadgets conceding suddenly over the air. The topology of the system is changing an incredible piece of the time in light of the advantageous idea of its inside focuses. The security challenges ascend taking into account self-game-plan and self-reinforce limits. By the by, existing mysterious organizing shows depending upon either ricochet by-skip encryption or excess traffic either produce imperative expense or can't give full namelessness security to information sources, targets, and courses. The imperative expense raises the trademark asset limitation issue in MANETs particularly in natural media remote applications. To offer high absence of definition assurance expecting for all intents and purposes no effort, we strong secure anonymous location based routing (S2ALBR) protocol for MANET utilizing optimal partitioning and trust inference model. In S2ALBR appear, first segments a system into zones utilizing optimal tug of war partition (OTW) algorithm. By at that point, figure the trustiness of each reduced focus point utilizing the imprisonments got signal quality, versatility, way debacle and joint exertion rate. The arrangement of trust calculation is advanced by the optimal decided trust inference (ODTI) model, which gives the trustiness of each adaptable. By then picks the most basic trust ensured focus point in each zone as generally engaging trade habitats for information transmission, which structure a non-unquestionable bewildering course. The introduction of proposed S2ALBR show is examined by various testing conditions with Network Simulator (NS2) instrument.

Modified Energy Efficient with ACO Routing Protocol for MANET

Due to the specific design of the network upon the requirements of the demands as well as the situation at which the setting up of a physical network is impossible, a significant role is played by mobile ad-hoc network (MANET) in the applications of military. Various critical tasks like robust & dynamic military workstations, devices as well as smaller sub-networks within the battle field are handled by the presented network type controls the infrastructure less communication. A highly demand of the efficient routing protocol’s design is existing which ensures safety as well as reliability to transmit the extremely vulnerable as well as the secret military data within the defense networks. The designing of an energy efficient layer routing protocol within the network on behalf of the military applications is done in this method and the simulation is done with the help of a novel cross layer approach of design for increasing the reliability as well as the lifetime of the network. However, the optimum path selection is not allowed by PDO-AODV technique. Therefore, a novel ACO-DAEE (Ant colony optimization with delay aware energy efficient) to select an optimum path as well as to mitigate the delay time within the network system is proposed. Maintaining the optimum paths within the network while transmitting the data effectively is the major objective. With respect to packet delivery ratio, end to end delay, and throughput, it is indicated by the simulation outputs that the performance of ACO-ADEE is quite good. The efficiency of this technique is verified in the simulation outcomes using NS2 software.

Mobility Aware Quality Enhanced Cluster Based Routing Protocol for Mobile Ad-Hoc Networks Using Hybrid Optimization Algorithm

Wireless Sensor Networks (WSN) utilizes more nodes to forward messages and information from source node to destination node and these nodes are battery-powered devices. Thus, Energy saving is always vital role of Routing Protocols which need to maximize the lifetime of WSN. Mobile ad hoc networks (MANET) are self-starting and self-constructing multichip wireless networks in which, the assembly of the system deviates vigorously. This is mainly due to the mobility of the nodes. The nodes in the network not only act as hosts but also as routers that route data from other nodes in network. MANETs require an efficient routing protocol that achieves the quality of service (QoS) mechanism. They are not considering the mobility as one constraint for those problems. Because, mobility of nodes causes frequent link failures and high error rates, so it makes difficult to maintain the desired QoS in the network. To overcome those problems, we propose mobility aware routing protocol for MANET using hybrid optimization (MARP-HO) algorithm, which maximizes the QoS in data transmission. The proposed routing protocol comprises of two phases. The clustering process consists of cluster formation and cluster head (CH) selection. First, the energy efficient clustering is done by improved animal migration optimization (IAMO) algorithm. Then, we gather multiple constraints are energy consumption, received signal strength, mobility and cooperative rate from each cluster member. The gathered constraints used to compute the node cost of each cluster member, here the highest cost node act as CH of cluster. Second, we compute routing path between source–destination using improved ant colony optimization (IACO) algorithm. The proposed MARP-HO routing protocol is compared with existing state-of-art routing protocols in terms of energy consumption, delivery ratio, loss ratio, link stability, delay, network lifetime, number of dead nodes and throughput.

An Efficient Route Failure Detection Mechanism with Energy Efficient Routing (EER) Protocol in MANET

Mobile ad-hoc network (MANET) is a network with two or more number of nodes with restricted energy constraint. The high dynamic nature in MANET attracts needs to consider the energy efficient features in their construct. The routing protocol is an important criterion to be considered for evaluating the performance of the MANET. Energy consumption plays vital role in MANET. Hence designing the scheme that supports energy efficient is much needed for the high dynamic MANET environment concerned. This paper proposes the Energy Efficient Routing (EER) protocol based on efficient route failure detection. The Scope of this paper is to suggest a fresh routing procedure for Mobile Adhoc Network minimizes unsuccessful communication. The projected procedure practices three important criterions to locate the path that assure authentic communication. The channel caliber, connection caliber and node’s residual energy is important reason for the failure of the node in MANET. Hence, the suggested routing mechanism believes these three different parameters to choose the finest node in the route. The reliable transmission and reception are attained by transferring information through route nominated by the suggested system verified by means of NS-2 simulator.

IMPACT OF BLACK HOLE ATTACK ON THE PERFORMANCE OF DYNAMIC SOURCE ROUTING AND OPTIMIZED LINK STATE ROUTING PROTOCOLS IN MANETS

Mobile Ad-Hoc Networks (MANETs) are a collection of mobile nodes which are free to move from one place to another place without a central control entity. In MANETs the nodes are dependent on each other and the communication among mobile nodes is multi-hop due to which there are security issues in the MANETs protocols. Optimized Link State Routing (OLSR) and Dynamic Source Routing (DSR) protocols are mostly used as proactive and reactive routing protocols in MANETs. This research work analyzed the performance of the OLSR and DSR protocols in the presence and absence of black hole (BH) attack in terms of throughput, end-to-end delay, packet delivery ratio (PDR), and network load in various scenarios using OPNET Modeler 14.5 simulator. The results obtained in this research show that BH attack significantly degrades the performance of both DSR and OLSR protocols but due to the reactive nature of DSR routing protocol the performance is more degraded in DSR routing protocol as compared to OLSR routing protocol in the presence of BH attack.

RETRACTED ARTICLE: Heuristic ant colony and reliable fuzzy QoS routing for mobile ad hoc network

The furthermost important issues in mobile ad hoc network (MANET) are to provide a multi-path and multi-constraint qualify of service (QoS) routing for uninterrupted communication between the nodes. On one hand multi-constrained QoS routing deal with identifying paths that assure numerous autonomous QoS limitations and on the other hand, multi-path refers to the identification of multiple paths. Besides due to higher rate of topological changes and the energy constrained nodes in the network, literature survey provides us ant colony optimization (ACO), a unique variety of optimization procedure which was found to be extremely convenient for identifying reliable routing. To deal with following concerns, we suggest a multi-path multi-constraint energy-efficient routing method. In the projected method, calculate the metrics such as end to end delay and QoS monitoring agents collect, link stability, energy consumption, available bandwidth, and packet loss rate. The proposed method is called as the heuristic concurrent ACO and reliable fuzzy (HEACO–RF) QoS routing protocol for MANET. The HEACO–RF QoS routing protocol for MANET includes two phases. In the first phase, the ant colony optimization algorithm is modified to identify a deposit of candidate routes among a pair of source and destination. While identifying the candidate routes along with the QoS metrics, heuristic factors and reliable fitness functions are also considered. In the second phase, the reliability technique is used to measure each path and the paths with high reliability is selected by the ant agents using fuzzy logic based on the metrics link stability, residual energy, and packet loss rate. Simulation outcomes prove that HEACO–RF QoS routing protocol decreases the energy consumption and improves the packet delivery ratio, packet loss rate with minimum delay.

Determining an optimum zone radius for zone routing protocol (ZRP) based on node mobility

Mobility is one of the important issues in Mobile Ad hoc Networks (MANET). By definition, MANET nodes are free to move around and this may cause difficulty in routing. MANET routing protocols must consider this factor when making routing decision. Zone Routing Protocol (ZRP) is a hybrid routing protocol, which utilizes the proactive and reactive routing protocols advantages. ZRP proactively maintains routing information within a routing zone, while reactively discovering routes to destinations beyond the routing zone. Since ZRP is based on the concept of routing zone, determining an optimum routing zone radius has the major impact on the performance of that protocol. In this research, we studied the effect of zone radius on the performance of ZRP with different levels of node mobility. Node mobility is defined using two different parameters: node speed and pause time. Based on the simulation results, ZRP protocol using zone radius of two provides the best packet delivery fraction, throughput and normalized routing load. However, a larger zone radius will provide a lower delay.

An Energy-Efficient Routing Protocol in Mobile Ad-hoc Networks

In recent time, with the fast development of the mobile system, Mobile Ad-hoc Networks (MANETs) have been fucus studied and applied in many areas such as rescue, military, medical applications and smart cities. Due to the characteristics of MANETs, routing protocols must be designed to be flexible, energy-efficient and highly performance achievable. Increasing network lifetime by reducing energy consumption level is a major method in the design of saving energy routing protocols in MANETs. In this study, we propose an improved routing protocol from AODV with a new cost function, applied to MANETs. The simulation results show, our proposed protocol saves energy consumption, increases network life, packet delivery rates, and improves performance over AODV

MAC Layer Energy Consumption and Routing Protocol Optimization Algorithm for Mobile Ad Hoc Networks

Mobile ad hoc network is a network composed of mobile terminals without infrastructure. Due to its fast-networking ability, it is widely used in smart cities, car networking, military, agriculture, medicine, and other fields. Routing technology is a key technology in the field of MANET (mobile ad hoc network). The energy consumption is optimized through the technical network simulator NS-3, and the nodes in the MANET routing protocol can accurately simulate the problem, thereby optimizing the MAC layer of important research tools. This article combines the advantages of the lithium-ion (lithium) battery model. Compared with the KiBaM battery model, the effective charge in the KiBaM model simulates the output voltage well, which can reflect the battery capacity effect rate and the recovery effect of the lithium-ion-KiBaM battery model. The model can respond to the characteristics of the output voltage as the society gets lower and lower. In order to solve the problem that the analytic solution of differential equations cannot be obtained in the model, a numerical solution of the optimization algorithm is proposed based on the implicit Runge–Kutta method. The MAC layer energy consumption and routing protocol optimization algorithm proposed in this paper can be applied well in various fields.

Mobile ad-hoc network routing protocols of time-critical events for search and rescue missions

The most important experiences we discovered from several disasters are that cellular networks were vulnerable, and the loss of the communication system may have a catastrophic consequence. Mobile ad-hoc networks (MANETs) play a significant role in the construction of campus, resident, battlefield and search/rescue region. MANET is an appropriate network for supporting a communication where is no permanent infrastructure. MANET is an effective network that uses to establishing urgent communication between rescue members in critical situations like, disaster or natural calamities. The sending and receiving data in MANET is depending on the routing protocols to adapt the dynamic topology and maintain the routing information. Consequently, This paper evaluates the performance of three routing protocols in MANET: ad-hoc on-demand distance vector (AODV), destination sequenced distance vector (DSDV), and ad-hoc on-demand multipath distance vector (AOMDV). These protocols are inherent from different types of routing protocols: single-path, multi-path, reactive and proactive mechanisms. The NS2 simulator is utilized to evaluate the quality of these protocols. Several metrics are used to assess the performance of these protocols such: packet delivery ratio (PDR), packet loss ratios (PLR), throughput (TP), and end-to-end delay (E2E delay). The outcomes reveal the AOMDV is the most suitable protocol for time-critical events of search and rescue missions.

Yates Algorithm to Analyze the Performance of MANET Routing Protocol

To test the performance of any routing protocol in Mobile Ad hoc Network (MANET), the re-searchers simulate their scenarios several times with different simulators to get either positive or negative results. This operation of the simulation can last many hours and sometimes several days depending on the performance either of the software or the hardware, and the number of factors used to analyze. In this paper, we propose a new method reckons on the Yates algorithm that are considered as a solution to evaluate the performance of any MANET routing protocols under the effect of any number of factors. This approach allows creating a simulation model in the form of mathematical formulas. To check the efficiency of our proposed method we chose Optimized Link State Routing Protocol (OLSR) as MANET routing protocol and the effect of four factors which are: The Black Hole attack, Worm Hole attack, Node Speed and the Pause Time.

SIBLAR: a secured identity-based location aware routing protocol for MANETs

A mobile ad-hoc network (MANET) is a self-organising distributed wireless network without any central infrastructure support wherein every participating node independently acts as a router. Several routing protocols are available for information dissemination in MANETs but their efficiency is limited due to security breaches. Providing security schemes for robust information dissemination is of high prominence for the real time deployment of MANET applications. From the existing literature, it is understood that very few research efforts were made to ensure security for routing protocols and there is a huge scope for the design and development of secured routing protocols for MANETs. In this paper, we have considered the security issues with respect to location aided routing (LAR) and proposed a secured identity-based location aware routing (SIBLAR) protocol to achieve system security with improved key refreshment mechanism. MANET scenarios were created in ns2 and the efficiency of the proposed SIBLAR protocol was evaluated based on certain performance metrics. In the presence of security attacks, the proposed SIBLAR scheme is found efficient when compared to basic LAR.
