Mobility Based Performance Analysis DYMO, STAR & DSR Adhoc Routing Protocols

The wireless adhoc network is comprised of nodes (it can be static or mobile) with wireless radio interface. Each host is equipped with a CSMA/CA (carrier sense multiple access with collision avoidance) transceiver. These nodes are connected among themselves without central infrastructure and are free to move around. It is a multihop process because of the limited transmission range of energy constrained wireless nodes. This creates the scenario of multihop, where the packets originated from the source host are relayed through several intermediate hosts before reaching the destination. Routing is the process of finding a path from a source to destination among randomly distributed routers in dynamic network. In this paper table driven routing protocol STAR and on demand routing protocols DSR, DYMO based on IEEE 802.11 are surveyed and characteristic summary of these routing protocols is presented. Their performance is also analyzed on performance metrics throughput, jitter, data delivery ratio and end-to-end delay by varying nodes mobility with CBR data traffic load using QualNet 5.0.2 network simulator.
