Abstract :
In this paper a Rayleigh fading model based reliability-centric routing algorithm is proposed for Wireless Sensor Networks (WSNs). The proposed scheme is optimized with respect to minimal power consumption to improve longevity as well as to ensure reliable packet transmission to the Base Station (BS). Reliability is guaranteed by selecting path over which the probability of correct packet reception of the transmitted packet will exceed a predefined threshold at the BS. It will be pointed out that reliable and power efficient packet forwarding over WSN can be mapped into a constrained optimization problem. This optimization is then reduced to a shortest path problem with specific link metrics solved in polynomial time.
