Security improvements Zone Routing Protocol in Mobile Ad Hoc Network
International Journal of Computer Applications Technology and Research
The attractive features of ad-hoc networks such as dynamic topology, absence of central authorities and distributed cooperation hold the promise of revolutionizing the ad-hoc networks across a range of civil, scientific, military and industrial applications. However, these characteristics make ad-hoc networks vulnerable to different types of attacks and make implementing security in ad-hoc network a challenging task. Many secure routing protocols proposed for secure routing either active or
... tive, however, both of these protocols have some limitations. Zone Routing Protocol (ZRP) combines the advantages of both proactive and reactive routing protocols. In this paper we analyze the ZRP security improvements. Considering the delivery rate of packets, routing overhead, network delay, Simulation results show that Protocols operate under different constraints and none of the protocols are not able to provide security for all purposes.

Proactive routing protocols: In it, all the nodes continuously search for routing information with in a network, so that when a route is needed, the route is already known. If any node wants to send any information to another node, path is known, therefore, latency is low. However, when there is a lot of node movement then the cost of maintaining all topology information is very high. Hybrid routing protocols: These protocols incorporates the merits of proactive as well as reactive routing protocols. A hybrid routing protocol should use a mixture of both proactive and reactive e approaches. Hence, in the recent years, several hybrid routing protocols are proposed like ZRP .
