Cluster based route discovery technique for routing protocol in MANET

Mobile Ad hoc Networks (MANETs) as the name signifies is a network formed by collection of mobile ad hoc devices (nodes). It is a kind of infrastructure less wireless network which is autonomous decentralized where each node is free to move anywhere at any time. Due to the mobility of nodes routing is main issue of research, since the wired network´s routing protocols cannot be used here. Routing in MANETs is mainly of two types proactive and reactive. A proactive routing protocol(DSDV, WRP, CGSR) maintains the route between all pairs of nodes in the network all the times whereas a reactive routing protocol (AODV, DSR, TORA) is an on demand routing protocol where route is found only when required which has great advantage over proactive protocols. In this paper a new cluster based route discovery algorithm for reactive routing protocol i.e. Ad hoc On Demand Distance Vector (AODV) is proposed, since for the existing algorithms control overhead is very high which consumes a lot of available bandwidth. In the future performance evaluation of the proposed technique can be done and the results thus obtained can be compared with the existing algorithms. We hope that control packet overhead will be less in case of proposed algorithm.
