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 reactive, 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.
