PERFORMANCE OF ROUTING PROTOCOLS WITH VARYING NODE DENSITY AND GROUP MOBILITY MODEL IN MOBILE AD-HOC NETWORK

Abstract

Mobility model and node density have significant role in term of performance of routing protocols in a mobile ad-hoc Network. The performance of MANET routing protocols have been evaluated in terms of performance metrics namely Average Throughput (bits/s), Average End to End Delay (s) and Average Jitter (s). To evaluate the performance of AODV, DSR, DYMO, OLSR, Bellman Ford and ZRP routing protocols, the researchers have conducted simulation based study using QualNet simulator. Group mobility model has been selected to show the realistic environment of the movement of mobile nodes under the varying node density and CBR traffic pattern. The results of the study have shown that variations in performance of the routing protocols have seen with varying node densityof mobile nodes in MANET.
