Performance evaluation of reactive routing protocols in MANET networks using GSM based voice traffic applications

摘要

The mobility of nodes results in frequent and unpredictable changes of network topology, leads to regular route changes, network partitions and possibly packet losses, making routing a challenging task in MANET network. The mostly used routing protocols in such networks are proactive, reactive and hybrid, but a reactive routing strategy is the most popular technique for wireless adhoc routing that provides a scalable solution to relatively large network topologies. This paper evaluates the performance of AODV- and DSR-reactive routing protocols in MANET network using GSM quality voice traffic by calculating matrices such as voice end-to-end delay, network load, throughput, number of hops per route, route discovery time, voice traffic-sent and -received using OPNET Modeler 14.5.
