Abstract: In this paper, first we present a performance comparison of Associativity Based Routing (ABR) and Ad hoc On-demand Distance Vector (AODV) routing protocols. Delay, throughput and energy consumption are the performance metrics that are used for the comparison. We also carry out scenario based performance evaluation of ABR. We propose a technique to reduce the packet size by changing the mechanics of the protocol, and evaluate the proposed technique considering delay, throughput and energy consumption. We also propose and study a scheduling mechanism (neighbour-state dependent scheduling) that uses the overhead information in ABR routing packets to improve the performance.

Keywords: MANET; ABR routing packets; AODV; scheduling; mobility models; performance evaluation; performance enhancement; link stability; routing protocols; delay; throughput; energy consumption; associativity based routing; ad hoc on-demand distance vector; wireless communications; ad hoc networks; mobile networks.
