Abstract

Background & Objective: ZRP is the most propitious and well acknowledged hybrid routing Protocol in MANET. ZRP proves to perform better under scalability conditions as compared to the table driven and on-demand routing protocols. However, for large networks with an increase in both traffic and mobility the performance of ZRP gets affected. The overhead and latency are majorly affected. This paper analyses the benefits of Clustering when it comes to scalability and proposes an algorithm using the clustering mechanism. The algorithm also incorporates a novel technique called the route Aggregation technique at the Cluster Head.

Conclusion: The simulation results are descriptive of the improvement in the End to End Delay, Normalized Routing Load and Packet Delivery ratio, under varying nodes, connections and mobility. The new Algorithm is called ZRP-RA.

Keywords: Scalability, Clustering, ZRP-RA, Route Aggregation, Cluster Head, adhoc network, routing protocol.
