Design and performance analysis of mobile Ad hoc network with reactive routing protocols

A Mobile Ad Hoc Network (MANET) is a group of several wireless mobile nodes, that communicate with each other without requiring any pre-existing infrastructure, forming an arbitrary topology and there is no centralized administration present. In wireless MANET, each mobile node can act as a receiver and a router and they are free to move randomly. Because of the dynamic topology of the MANETs, routing is one of the crucial issues in these network structures. Routing protocols help in setting up communication between mobile nodes and they also affect the performance of the network. A variety of routing protocols have been designed for MANET. This paper shows design and performance analysis of Mobile Ad hoc Networks, using the reactive routing protocols like AODV which is Ad hoc On-demand Distance Vector and AOMDV which is Ad hoc On-demand Multipath Distance Vector. The simulation is performed using the network simulation software NS2.
