Comparison of routing protocols for MANET and performance analysis of DSR protocol

Abstract

MANET, a multihop mobile adhoc network is comprised of mobile nodes which communicate over radio. Each host is equipped with a CSMA/CA (carrier sense multiple access with collision avoidance) transceiver. Mobile ad-hoc networks are suitable for temporary communication links as they do not require fixed infrastructure. The communication among routers is difficult due to its frequent changing network topology and requires efficient and dynamic routing protocol. This presents comparison of popular broadcast based proactive, reactive and hybrid adhoc routing protocols. Further, the performance of Dynamic Source Routing (DSR), an on-demand, routing protocol based on IEEE 802.11 is examined on performance metrics throughput, end-to-end packet delay, jitter and salvaged packets using QualNet 5.0.2 network simulator. © 2011 Springer-Verlag Berlin Heidelberg.
