Optimization of Zone Routing Protocol

Abstract

Reactive and proactive protocols have several advantages in ad hoc network. Proactive protocols provide less delay and reactive protocols uses less bandwidth, but it in order to use these advantages properly, it is better to use them in a combine manner rather than using them independently. A Hybrid protocol takes advantages of these protocols and overcomes the disadvantages of both. A popular hybrid protocol is Zone Routing Protocol. As the name implies the whole network is splitted in different zones. For routing inside the zone proactive protocol is used and between the zones reactive protocol is used. Optimization of ZRP using different radius and nodes on NS2 is executed inside the paper. TORA is used as within the nodes and DSDV between the zones. Performance is judged by using PDR as a parameter. This is done to know at which radius and number of nodes the performance of ZRP is the best. ZRP is a not a distinct protocol as it provide framework for other protocols. KEYWORDS: ZRP, TORA, DSDV, PDR, NS2.
