Improved-Hraran : A New Approach to Improve Performance of Hraran Routing in Manet

Abstract
Ad hoc wireless networking is a separable part of wireless networking which is getting popular among users due to its various features like it is easy to implement and access, reliable data delivery. With the increased number of users the ad hoc networks suffers from issues like security, efficient routing, lack of effective relay node selection etc. within last few year a large number of researches had been conducted in direction to solve these issues as most of the work had been conducted by using effective routing protocols and HRARAN is one of these protocols. It was observed that in traditional HRARAN protocol only reputation of the nodes was considered for electing the relay nodes for routing. Hence, this study provides an improved HRARAN (IHRARAN) which elects the nodes for routing on the basis of reputation value of nodes, residual energy of nodes and connectivity of nodes. The proposed work creates a route to the destination by electing the hops for path on the basis of their reputation value, connectivity of the node. In this initially the network is created and then source and destination node is elected. After selecting the source and destination node the shortest path is created between them by choosing the next hops on the basis of evaluation of considered parameters. The proposed work is evaluated on the basis of various performance parameters such as packet delivery ratio and throughput. The proposed protocol is simulated by using MATLAB software. The comparison is performed among ARAN (Authenticated Routing), HRARAN and IHRARAN. Simulation was performed on the proposed routing protocol on MATLAB simulation software and the observed results have shown the efficiency of proposed work. It is observed that the throughput level increased up to 30% as compare to the conventional routing protocols that are ARAN and HARARN.
