Performance Evaluation of Mobility Models on MANET Routing Protocols

Abstract

With the advancement of wireless technology, portable devices that are capable of wireless communication have become extremely popular making possible the establishment of wide ubiquitous networks. Mobile Ad Hoc networks (MANETs) are wireless networks where the exchange of messages between the nodes does not rely on any pre-deployed infrastructure. This architecture, nevertheless, suffers from a highly unstable topology as the links between the nodes break constantly due to movement of the users. Path routing and protocol selection are the key strategies behind the design of any wireless network. In this paper we study and evaluate the effect of mobility on the routing protocols viz. AODV, DSDV, DSR and OLSR in terms of packet delivery ratio, average end-to-end delay and normalized routing load.

Route Availability as a Communication Quality Metric of a Mobile Ad Hoc Network

“…A variety of routing protocols have been proposed for MANETs [2][3][4][5][6][7][8][9][10][11][12][13], and various metrics have been used to assess their performance, such as packet delivery ratio (PDR), throughput, end-to-end delay, routing overhead, path length, packet loss rate, jitter, path lifetime, and mean opinion score (MOS). Table 1 lists metrics used in different references.…”

“…If routing control is to be carried out based on these metrics, nodes need to exchange basic information from which these items of information can be calculated. Routing overhead [2,5,7] is used for protocols that are designed to improve the performance and stability of the routes to be established but it does not indicate the quality of the routes established. Path lifetime [10,11], which is based on the remaining battery levels of relay nodes, is an important assessment metric but is not fit for assessing the nonuniformity (represented by repeated connections and disconnections) that the current paper focuses on.…”

“…Metrics used to represent the data communication quality of MANETs are packet loss rate [2,3] and throughput [2,[4][5][6], end-to-end delay [2,5,7,8], and packet delivery ratio (PDR) [2,4,6,7,9]; these have been used in IP (Internet Protocol) networks. These are designed for application to data communication after communication routes have been established, and thus are not necessarily a suitable metric to assess the communication quality for networks like MANETs in which routes are not uniform because they are constantly disconnected and re-established as a result of node mobility.…”

“…These are designed for application to data communication after communication routes have been established, and thus are not necessarily a suitable metric to assess the communication quality for networks like MANETs in which routes are not uniform because they are constantly disconnected and re-established as a result of node mobility. Regarding communication route establishment, routing overhead [2,5,7], path length [2], and path lifetime [8,10,11] are used as metrics to assess the performance of routing protocols and routes. For applications such as video streaming, in which the user's quality of experience is important, jitter [6] and MoS (Mean Opinion Score) [9,12,13] are also used in addition to the above metrics.…”

Performance Analysis of Table Driven and Event Driven Protocols for Voice and Video Services in MANET

“…Naseer et al using multimedia application analysed the TORA, AODV and OLSR with the help of opnet [18]. Gupta evaluated the mobility effect of MANET routing protocols in terms of packet delivery ratio and end to end delay by using ns-2 simulator, and observed AODV performed better [19]. Mostafavi et al has reviewed proactive and reactive routing protocols by using FTP traffic, and three parameters end to end delay, load and throughput, analysed with opnet modeller [20].…”
