Performance evaluation of MANET routing protocols based on QoS and energy parameters
International Journal of Electrical and Computer Engineering (IJECE), 2020
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. 1. INTRODUCTION Since 1990, MANET has been a popular research topic and MANETshave also been used in different applications. Supporting mobility of nodes in MANET with hundreds of nodes has been a main challenge in this kind of network, due to limited wireless transmission range, packet losses because of transmission errors, mobility induced route changes, and energy constraints [1].Therefore energy efficiency is important metric for sending the data from source to destination. Routing protocol is used for maximizing the energy efficiency of the network [2, 3]. There are a number of routing protocols for ad-hoc networks [4, 5], they are categorized into Proactive Routing and Reactive routing.Proactive routing protocols or table-driven protocols follow an approach similar to the one used in wired routing protocols. Each node maintains routing table which contains information about the network topology even without requiring it. So, the route in the network is predetermined for example DSDV [6, 7]. Reactive routing or on-demand protocols does not attempt to continuously determine the network connectivity, rout is discovered whenever it is needed. There are various reactive protocols such as AODV [8, 9]. The major difference between AODV and DSDV is that DSDV, the source and the intermediate nodes store the neighbor's node information according to each flow for data packet transmission. It generates no more packets for communication. The connection setup delay is lower and it consumes more share of the bandwidth in addition to taking more time to build routes. Intermediate nodes can lead to inconsistent routes. DSDV protocols are not appropriate for large network or highly dynamic as they need to maintainnode entries for each and every node this leads to increased control message overheads which can
Performance Evaluation of Energy Efficient Routing Protocols for MANET
International Journal of Computer Applications, 2011
MANET are a dynamic and infra structureless networks. The major constraint of this type ao networks are Energy optimization because the nodes involved in these type of networks are battery operated. To improve the lifetime of these network can be improving the energy levels of the individual nodes of the network. This paper presents an analysis of the effects of different design choices for this on-demand routing protocols in wireless ad hoc networks. The analysis of this paper is based on the Dynamic Source Routing protocol (DSR), which operates entirely on-demand. This paper compares an existing DSR protocol with the proposed two modified DSR protocols named Maximised Energy Efficient Routing protocol (MEER) and Cluster Based Energy Efficient Routing protocol(CBEER). Based on the simulation, it is found that the energy efficiency and percentage of reliable delivery of packets in the MEER and CBEER protocol are considerably higher than the existing DSR protocol. Also these proposed protocols considerably increases the life time of the network.
Comparative Study on Performance Evaluation of Routing Protocols in MANETs
A mobile ad hoc network (MANET) is a collection of wireless mobile nodes communicating with each other using multi-hop wireless links without any existing network infrastructure or centralized administration. Due to varying network topology the most common challenging factor in MANET is routing [1][2]. The purpose of this paper is to study, understand, analyze and to evaluate the performance between four mobile ad-hoc routing protocols: Ad-hoc On-demand Distance Vector (AODV), Destination sequenced distance vector (DSDV), Dynamic Source Routing (DSR) and Zone Routing Protocol (ZRP). DSR has the optimum performance in terms of mobility and speed in small scale networks but it loses its performance when the network size is increased. AODV is best suited when the load of the network is increased. ZRP is hybrid nature and comparable performance in average end-to-end delay and average throughput; but it is the worst performance in packet delivery ratio. This simulation results were analyzed by graphical manner and trace file based on different metrics; such as average throughput, packet delivery ratio (PDR) and average end to end delay.
Performance Evaluation of Position-based Routing Protocols using Different Mobility Models in MANET
A Mobile Ad hoc network (MANET) is a dynamic selforganizing multi-hop wireless network. Owing the random and unpredictable movement of the mobile nodes, the topology is changing rapidly and frequently. In MANET, where is no routing infrastructure like fixed routers and routing backbones, all MNs participate in the routing process. Recently, position-aware routing protocols, and because of their simplicity, position awareness, and scalability, are the most routing protocols used with MANET. In recent years, a variety of position-aware routing protocols have been developed. The efficiency of such protocol affects by the used underlying mobility model. Thus, wrong selection of the Mobility model may has devastating consequences on the performance MANET. Research efforts haven't focused much in evaluating their performance when applied to different mobility models. In this paper, we have studied the effect of two different mobility models; Random Waypoint mobility model (RWP) and Boundless Mobility Model (BDM) on the performance of selected group of position-based routing protocols. The performance analysis was carried out by using the network simulator, Ns2. The simulation results clarify the performance of the selected routing protocols with three performance metrics.
This work evaluates the performance of three well known routing protocols in mobile ad-hoc networks, namely Ad-hoc On demand Distance Vector Protocol (AODV), Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm (TORA). Two scenarios were created using OPNET and extensive simulations were made on each scenario to evaluate the performance of the three protocols. Results were presented as a function of three performance metrics namely: throughput, delay and network load. In most simulations and overall, DSR and AODV performed better than TORA while DSR shows a better performance compare to AODV. In terms of throughput, DSR is better than any of the other two protocols for both scenarios while AODV shows a better result in delay than DSR and TORA. The lowest value of network load is generated in both scenarios when TORA is used than when any of DSR and AODV is used. Thus, DSR because of its highest value of throughput outperformed others, followed by AODV and then TORA.
Routing Protocols for Mobile Ad-Hoc Networks Performance Enhancement
Current research on routing protocols for Mobile Ad-hoc NETwork (MANET) has converged to several dominating routing protocols, including Optimized Link State Routing (OLSR), Ad-hoc Ondemand Distance Vector (AODV) and Dynamic Source Routing (DSR). At the same time, classic routing protocols such as Open Shortest Path First (OSPF) and Destination Sequenced Distance Vector (DSDV) are improved for the MANET context. Research efforts also focus on issues such as Quality of Service (QoS), energy efficiency, and security, which already exist in the wired networks and are worsened in MANET. This paper examines the routing protocols and their improvements. We discuss the metrics used to evaluate these protocols and highlight the essential problems in the evaluation process itself.

Energy is an important issue in MANET (Mobile Ad hoc Network). Nodes in network are working in presence of limited energy. So, energy efficient routing is needed for reducing energy consumption. Energy efficient routing schemes can greatly reduce energy consumption and extends the lifetime of the networks. Multipath routing protocol (AOMDV) having more than one path, if the first one is break then second provides the proper packet delivery, this causes reduced node energy consumption and the topology of MANETs always changes, due to the high mobility of nodes. This makes it more difficult to find the routes that message packets use when they are routed. The location based routing provides the location information of the destination to route a packet toward. This paper provides comparison and study on reduced energy consumption by using multipath protocol and performance which is evaluated by performance metrics in case of AOMDV and energy based AOMDV. Now here DREAM protocol is used with AOMDV to finding location of mobile nodes but not with energy but here measures their performance with both multipath protocols.
Survey and Performance Analysis of Routing Protocols in MANET
2014
A Mobile Ad-hoc Network (MANET) consists of several mobile wireless nodes. It is infrastructure-less, self organized and self configurable network in which the mobile nodes move arbitrarily. A routing protocol establishes correct and efficient route between mobile nodes and find the routes to facilitate communication within the network. Route should be discovered and maintained with minimum overhead and bandwidth consumption. Here topology based routing protocols, both proactive and reactive protocols have been considered for study. The performance of routing protocols (DSDV, AODV, OLSR, DSR, TORA, ZRP) is analyzed in terms of their packet delivery ratio, throughput, end-to-end delay, bandwidth, control overhead and energy consumption. We analyze the solution of routing in MANET and evaluate its performance using Network Simulator-2 (NS-2) under different network parameters.
