Evaluation of Multicast and Unicast Routing Protocols Performance for Group Communication with QoS Constraints in 802.11 Mobile Ad-hoc Networks

In Mobile Ad-hoc Network (MANET), portable devices like smartphones, or laptop PC can join together to make provisional networks without any infrastructure The objective of multicast or unicast protocols is to ensure an efficient route formation and flow control mechanism which is a very challenging issue for many group computing services in MANETs. MANETs can support several real-time applications like emergency rescue, and disaster relief operations which require minimum Quality of Service (QoS) to handle high traffic. Providing QoS for multimedia and group-oriented computing in MANETs becomes a real challenge due to the wireless medium and the mobility of operating nodes. Therefore, an investigation of routing protocols for one-to-many or many-to-many computing is important that supports acceptable QoS in MANETs. Numerous QoS metrics have been considered for the assessment like packet delivery ratio, latency, packet loss rate, control overhead, and throughput. By considering different network topologies and scenarios with different performance parameters, the primary goal of this study is to explore the challenges and factors for QoS services in MANET’s multicast communication. The outcomes of investigation can be used to design the future MANET protocol for multimedia applications. The performance results indicate that the increasing number of sending/receiving nodes may increase the overhead or latency of the network but capable of providing higher network throughput, carried out in NS-2. The results also indicate although MANETs can induce errors and packets are lost as part of the normal operating context, multicast AODV practice superior to the unicast protocol to various QoS in a wide range of scenarios with less overhead.

WITHDRAWN: Preemptive route maintenance methods

The performance of routing protocols in MANET has been investigated comprehensively in current years. Be that as it may, most steering conventions attempt to discover another way when congestion is said to have occurred. Such a methodology is proposed to bring about additional deferral, high bundle misfortune and requires huge overhead for distinguishing alternate way. An ideal directing convention is relied upon to identify blockage just as by adjusting to arrange congestion. Adaptability to congestion assists with expanding both achievement and productivity of steering. In this archive proposes a better AODV directing convention that endeavors to find another way if blockage is conceivable in a current way, utilizing a steering calculation called CAMFCR (Congestion Altering Most Flattering Check Routing). At first, CAMFCR isolates the system in to five districts as indicated by the methods for neighbors. After isolation of the system, it starts a most complimenting course revelation measure. When new ways were recognized, all the hubs in essential way intermittently compute its status of line at the hub level. This methodology, every hub will send an admonition message to its past hub if the past hub is probably going to be congested. Accordingly, the last hub will endeavor to recognize another way for the moving toward bundles to be sent through, by applying a most Flattering Check Routing technique. Along these lines, CAMFCR improves the system execution as far as lessening delay and steering overhead and expanding bundle conveyance proportion. The examination utilizing Ns-2 simulator which system found that CAMFCR is better over AODV and CAAODV steering technique.

Network Performance Evaluation of Different MANET Routing Protocols Configured on Heterogeneous Nodes

The recent communication technology tends to be wirelessly for the mobility reason. Mobile Ad-hoc Network (MANET) can be established without any infrastructure or centralized controller. It can be constructed quickly in rural areas, military zones, and in emergency cases like earthquake. Three different types of routing protocols were categorized according to their work’s nature, which are Proactive, Reactive and Hybrid routing protocols. Due to the mobility characteristic of MANET nodes, routing protocols play important role in determining the network efficiency where the network topology is changed frequently. Many studies are conducted to analyze network performance and specify the best routing protocol using different simulation tools. In this paper, the performance of network is analyzed and evaluated when heterogeneous nodes are configured with these three types of protocols under heavy traffic load (VOIP). The result of our simulation shows that OLSR protocol has the highest throughput among others while DSR protocol shows the best performance in terms of Network load. Generally, the performance of routing protocol differs depending on the network type and use.

Quality of Service EIGRP Routing Protocol on Campus Area Network

Quality of Service (QoS) is a method of measurement used to determine the capacity of a network to perform services. One of the QoS implementations is to manage the performance of routing protocol. The routing protocol is a method used to connect one router to another, to convey information correctly and to provide a guaranteed service. This study discusses the QoS of the Enhanced Interior Gateway Routing Protocol (EIGRP) applied to campus area network. EIGRP is a routing protocol which only available on Cisco routers and often refers to the proprietary protocol on Cisco. EIGRP can only be applied by Cisco routers and their fellow. Campus area network is an interconnection of computer networks within the campus area. Data exchange on campus network should be undertaken quickly and precisely to facilitate campus operations. The method used in this study was Network Development Life Cycle (NDLC) which consisted of several phases, namely analysis, design, simulation prototyping, implementation, monitoring, and management. The results of this study provided QoS with a throughput value of 77 bps, 0.53 percent of the packet loss value, 1.89 ms of latency, and 1.87 ms of jitter value. This indicates that the EIGRP routing protocol has a strong QoS value to be applied to campus area networks.

Monitoring of Gas Distribution Pipelines Network Using Wireless Sensor Networks

The Wireless Sensor Networks (WSNs) usually consist of several wirelessly connected sensors, to accumulate the data from some geographically scattered field and communicate it to a central database. Thus WSNs become an expedient tool to monitor the widespread gas distribution network such as Sui Northern Gas Pipelines Ltd. Pakistan. In this paper, some routing protocols performance has been investigated for gas pipeline monitoring applications. Simulated comparison of various routing protocols for WSNs deployed over gas distribution pipeline networks can give a valuable insight into the workability of the system, its performance, and other critical design parameters. The estimated lifetime of the network, node deployment for encyclopedic operation, the impact of energy harvesting from the field, and placement of the sink node at an optimal location are the key issues in the design of the WSN for pipeline network monitoring. All these issues are studied through simulation of various protocols for WSNs based upon real geographic locations of the nodes, real-world power levels and power consumptions by various processes of the wireless sensor networks. The simulations results show that DDEEC based WSN, for monitoring an actual Gas Distribution Network with a substantial quantity of nodes, can run with about 99.9% alive nodes for a benchmark period of 10 years. It was also evident from the comparison of the simulation results that the routing protocol DDEEC based system performs 0.4 to 34% better than the system based on LEACH, SEP, DEEC, and its other variants.

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.

Wireless sensor network (WSN) comprises of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, and pressure, and to cooperatively forward the collected information to the destination through the network infrastructure. As sensor nodes are energy constraint devices, therefore, the importance of energy efficient routing protocols has been increased. In order to minimize energy consumption, recently, a number of hierarchical routing protocols are proposed. For instance, LEACH is an elementary hierarchical routing protocol that employs clustering technique to achieve energy efficiency. A lot of research work has been performed to remove shortcomings and to improve the performance of hierarchical routing protocols. Therefore, a comprehensive review is required which can review state‐of‐the‐art technologies, analyze functional and performance aspects, and highlight hierarchical routing protocol issues and challenges in WSNs.

Moreover, it compares existing routing protocols to highlight key technological differences and provides performance comparison for the selected LEACH based routing protocols. Finally, the paper spotlights issues and challenges in existing routing protocols of WSNs, which can assist in future research for the selection of appropriate research domain and provide guidance in selection of energy efficient techniques in the design of energy efficient of routing protocols for WSNs.

A Survey of Routing Protocols for Underwater Wireless Sensor Networks

Underwater wireless sensor network (UWSN) is currently a hot research field in academia and industry with many underwater applications, such as ocean monitoring, seismic monitoring, environment monitoring, and seabed exploration. However, UWSNs suffer from various limitations and challenges: high ocean interference and noise, high propagation delay, narrow bandwidth, dynamic network topology, and limited battery energy of sensor nodes. The design of routing protocols is one of the solutions to address these issues. A routing protocol can efficiently transfer the data from the source node to the destination node in the network.

CCJRF-ICN: A Novel Mechanism for Coadjuvant Caching Joint Request Forwarding in Information Centric Networks

Information centric networking (ICN) shifts the focus of existing internet architecture from host-oriented to content-oriented model by enabling in-network caching and content-based forwarding. These ICN features help to increase network performance by decreasing content discovery delay, content server load, and network congestion. To route a content interest inside network such that content can be fetched with minimal time is a challenging task in ICN. The performance of the ICN routing protocol can be significantly improved if the decisions related to content chunk placement and request forwarding are taken in a cooperative fashion. This paper describes a novel strategy for co-operative caching joint request forwarding in ICN, focusing on decreasing content retrieval latency. To do so, the caching strategy leverages the concept of connected dominating set (CDS) for creating a virtual backbone network to eliminate caching redundancy and reduce content discovery delay. It considers content chunk placement and request forwarding tasks as strongly co-related procedures. It exploits the caching information so that the request is forwarded to a content router (CR) with the maximum likelihood of carrying needed data using the betweenness centrality (BC) of CR. The proposed approach also uses the Markov chain-based model to estimate CS hit likelihood and use it as decisional parameter while forwarding the interest packet. This mechanism helps to fetch the content within the shortest possible time duration. The CCJRF-ICN adopts the Dijkstra's shortest path routing and works in collaboration with the CDS-driven caching joint forwarding mechanism. The simulation study of CCJRF-ICN is done inside ns-3 based ndnSIM-2.0 simulator with performance measures like content store (CS) hit ratio, content discovery delay, mean hop distance, network load, and network overhead. The simulation outcomes demonstrate that CCJRF-ICN outperforms the state-of-the-art strategies for realistic topologies (GEANT, US-26, Euro-28) and shows improvement up to 5-35% against stated performance measures.

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.

<p>Video Streaming is a method to deliver multimedia content that allow files to be used or watched directly without the need to download and save it. Video streaming also include image processing, in image processing there is a component to compare the value of an image, that is PSNR. This research will compare the reactive and proactive routing protocol performance of AOMDV and DSDV using PSNR, Packetloss, and Throughput parameters in Wireless Mesh Network (WMN) for video streaming. The simulation uses 4, 16, 36, 64, and 100 nodes. The results of this research is AOMDV routing protocol with the greater variation in the number of nodes and the distance between nodes resulting in higher packet loss, decreasing throughput and decreasing values of PSNR. While in DSDV routing protocol with the greater variation in the number of nodes and distance between nodes has an impact on the increase of packetloss value, a very drastic decrease throughput value compared with the AOMDV routing protocol, a decrease in PSNR value and in some scenarios does not produce PSNR values. The comparison of PSNR values between the two routing protocols are also influenced by variations in the number of nodes and distances between nodes along with packetloss and throughput parameters. The greater packetloss will decrease the PSNR value generated.</p>

Performance evaluation of Energy Efficient algorithm using Spatial Trusted and Energy Aware Trusted Distance routing in WSN

Energy efficient routing is the most important design criterion for WSN (Wireless Sensor Network) as the nodes are either powered by batteries, or by other external power sources. In a Sensor network, the nodes communicate with each other in a multi-hop fashion. The availability of each node is equally important to the proper functioning of the network. The power failure of nodes greatly affects the overall performance of the network. The Quality of Service (QoS) has been measured using the parameters of data quality, energy utilization and position of the sensor nodes. In this paper Energy efficient routing algorithm called Location and Energy Aware Trusted distance source routing (LEATDSR), Energy-aware Spatial Trusted Routing algorithm (ESTR) and Intelligent Weighted Fuzzy Cluster based Secure Routing Algorithm (IWFCSRA) were analyzed in term of energy efficiency performance.

In the wireless communication, nowadays Flying adhoc network or UAV networks hold the most important place in the field of recent research topic. The drones or Un manned aerial vehicles which are enabled with camera, special circuit, sensors and advanced communication systems are coordinated among each other under the Network called as Flying adhoc network. FANET plays vital role in both military and civil applications. In spite of all these pros there are some unavoidable challenges and issues bonds around FANET. Since FANET possess the characteristics of dynamic rapid changing mobility, the choice of Routing protocol in FANET also open wide space in the field of Research. In our previous papers the topology based Routing protocols are analysed under different network scenarios and described the best performed one. It has been also found that the type OLSR is the better choice of FANET in terms of delay, Network load, Throughput and retransmission attempts. The OLSR routing protocol mechanism depends on the link state algorithm. It is proactive and table driven in nature. In order to maintain the topology information of the network, it completely supports the periodic exchanges of messages among themselves. OLSR is good in compacting the size of information sent in the messages. It avoids flooding by controlling the retransmissions. To exhibits this, the protocol utilizes multi point relaying techniques. It also provides optimal routes and this is completely suitable for dense and large networks. In this paper the performance of OLSR is investigated and analysed under 4 different network scenarios and different data rates. In a simulation using OPNET, the results show that the Optimized link state routing protocol has greater improved key indicators.

Performance and evaluation of location energy aware trusted distance source routing protocol for secure routing in WSNs

Objectives: To propose a suitable algorithm for improving the network lifetime of Wireless Sensor Networks (WSNs). Methods/Findings: We proposed a suitable Location and Energy Aware Trusted Distance Source Routing (LEATDSR) algorithm. Here, the energy consumption, location and the data quality are equalized by the Quality of Service (QoS) based routing algorithms. In addition to this algorithm, an existing clustering algorithm is also incorporates for grouping the sensor nodes based on the trust, location, energy and distance. In this LEATDSR is capable of deciding the evaluation metrics which express the QoS. Moreover, a new trust mechanism is also introduced in this model that incorporates multi-attributes of various sensor nodes in terms of communication, data, energy, and recommendation. This new trust mechanism relies on an enhanced sliding window time by considering the occurrences of attack frequency for facilitating the discovery of anomalous behaviours of attackers. The enhanced energy utilization is established within the sensor nodes for performing the active data transmission. The performance of the proposed model is evaluated by conducting various experiments in a simulation environment which creates by using NS2. From the experiments conducted in this work, the average packet transfer rate is increased drastically when compared to existing models available in the literature.

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>

Traffic congestion control is becoming a popular field of research due to the rapid development of the automotive market. Vehicular ad hoc networks (VANETs) have become the core research technology for numerous application possibilities related to road safety. Road congestions have been a serious issue of all time since the nodes have high mobility and transmission range is limited, resulting in an interruption of communication. One of the significant technical challenges faced in implementing VANET is the design of the routing protocol, providing adequate information and a reliable source for the destination. We proposed a novel mechanism unmanned aerial vehicle (UAV)-assisted ad hoc on-demand distance vector (AODV) routing protocol (UAVa) for current-time traffic information accumulation and sharing to the entire traffic network and to control congestions before it happens. The UAV-assisted (UAVa) protocol is dedicated to urban environments, and its primary goal is to enhance the performance of routing protocols based on intersections. We compared the overall performance of existing routing protocols, namely ad hoc on-demand distance vector. The simulations were done by using OpenStreetMap (OSM), Network Simulator (NS-2.35), Simulation of Urban Mobility (SUMO), and VanetMobiSim. Furthermore, we compared the simulation results with AODV, and it shows that UAV-assisted (UAVa) AODV has significantly enhanced the packet delivery ratio, reduced the end-to-end delay, improved the average and instant throughput, and saved more energy. The results show that the UAVa is more robust and effective and we can conclude that UAVa is more suitable for VANETs.
