Survey of Reactive Routing Protocols for MANET
Chintan Patel · IOSR Journal of Electronics and Communication Engineering · 2013
A MANET is a collection of mobile nodes by wireless links forming a dynamic topology without any network infrastructure such as routers, servers, access points/cables or centralized administration.The nodes are free to move about and organize themselves into a network.These nodes change position frequently.The main classes of routing protocols are Proactive, Reactive and Hybrid.A Reactive (on-demand) routing strategy is a popular routing category for wireless ad hoc routing.It is a relatively new routing philosophy that provides a scalable solution to relatively large network topologies.The design follows the idea that each node tries to reduce routing overhead by sending routing packets whenever a communication is requested.DSR and AODV are reactive route discovery algorithms where a mobile device of MANET connects by gateway only when it is needed.The performance differentials are analyzed using varying performance metrics.These simulations are carried out using the ns-2 network simulator.
