REAQ-AODV: Route stability and energy aware QoS routing in mobile Ad Hoc networks

Providing quality-of-service (QoS) support for Ad Hoc networks is a challenging task due to dynamicity, lack of centralized control, constrained resources and unreliable nature of radio channels and in Mobile Ad hoc networks. Finding a path that remains valid for sufficiently longer period is also a critical task in MANET. In this paper, we propose a novel, stability and energy based QoS routing protocol which is an extension of our route stability and energy based routing (RSEA), to support applications with throughput and delay constraints. In this model, we compute the reliability factor based on the route stability and the residual energy of the intermediate nodes satisfying the admission control. The route with the highest reliability factor is selected for data transfer from source to destination among all the feasible routes. The proposed model has shown better results in terms of packet delivery ratio, control overhead and end-to-end delay in comparison with RSQR, LEAR.
