Development of Advanced Location Based Efficient Routing in MANETs

Abstract

Mobile Ad Hoc Networks (MANETs) use routing protocols that are anonymous and provides hiding of crucial node identities and routes, so that outside observers cannot trace the route and also the crucial nodes, in this way it provides better protection. There are many existing anonymous routing protocols which rely on either hop-by-hop encryption or redundant traffic. Both the methods used are highly costly and also they don't generate full anonymity protection to the nodes or routers and also the source and destination. As the cost is high while using this anonymity protection categories it creates problem in the resource constraints in MANETs especially in multimedia wireless applications high cost exacerbates the intrinsic resource constraint problem are seen in MANETs especially in wireless multimedia applications. To provide protection at low cost, an Advanced Location-based Efficient Routing in MANET (ALER).It dynamically partitions the network field into different zones and it randomly chooses nodes in zones as intermediate relay nodes, these relay nodes forms a non-traceable anonymous route, not only that the proposed protocol also helps in hiding the sender and the destination also very efficiently. It also has strategies to effectively counter intersection, timing attacks. In this routing technique it has tried to overcome the Sybil attack issues which were not solved by the routing technique. It has prevented the Sybil attack entirely by having forwarding nodes check source routes for loops.
