Abstract: A mobile ad-hoc network (MANET) is a wireless, self-organizing, self-configuring network of mobile nodes or devices that are connected without any specific infrastructure. The mobile nodes can receive and forward packets as a router. In this study compare the performance of four MANET routing protocols Ad hoc On-demand Distance Vector (AODV), Dynamic source routing (DSR), Optimized Link State Routing (OLSR) and Destination Sequenced Distance Vector (DSDV). The performance differences are analyses basing on varying simulation time and number of nodes. The delay, throughput and packet delivery ratio are the common measures used for the comparison of the performance the protocols. These simulations are performed on NS-3 network simulator.
