MCDM Approach to Improve the Quality of Broadcasting Technique in Wireless Ad-hoc Networks


 Contemporary research work in the field of Wireless Ad-hoc Networks (WANETs) are focused on most important issue of performance, minimize the congestion in the network. A number of research proposals have come up with innovative query transmission approaches in order to scale down congestion, route latency and energy consumption to the feasible extent. It has been shown experimentally that these approaches have mainly focused on checking propagation of route query using query broadcast repealing technique which unfortunately paves way to additional routing overhead. This leads to increased energy-consumption which offsets the benefits. This paper introduces a self-aware query-broadcast approach which is dynamic in nature and obtains desirable path in discovery phase without counterbalancing the advantages reaped from confining the request zones. The proposed approach relies on Analytic Hierarchy Process (AHP), which utilizes the routing metrics in estimating the weighing factors for combined weight metrics. For evaluation of the proposed technique, critical and analytical assessment is done in terms of query-diffusion, packet-delivery ratio and route-latency. The results reveal the proposed approach is ideal, optimal and highly practical for application in WANETs.
