Delay Analysis of Manet Routing Protocols
Tooba Javed, Saima Zafar · 2012
Mobile Ad-hoc Networks (MANETs) are infrastructure-less networks comprising of nodes that are mobile and do not have fixed interconnections. These distinctive features render conventional routing algorithms unsuitable for these networks and designing special routing protocols for MANETs is an important area for ongoing research. Routing protocols that have been proposed till now can be categorized into three types, reactive, proactive and hybrid. This paper explicates and compares three significant routing protocols for MANETs, one from each category. We analyze these protocols in terms of end to end delay through simulations performed in Network Simulator (ns2) for varying network conditions like network load, mobility and network size. Our results show that none of the proposed protocols clearly outperforms others under all conditions. Although AODV and DSDV perform better when network congestion is less and TORA performs better for congested networks, there is a need to design a routing protocol that maintains its performance under all network and mobility conditions.
