The routing algorithm based on reliable path and efficient energy in wireless sensor network

In wireless sensor network (WSN), the reliability and energy consumption of nodes are very important parameters to extend the lifetime. This paper proposes a concept that balances reliability and residual energy to control the success rate of message transmission. By formulating the weights of the reliability and remainder energy, the reliability-energy metric is designed to measure routing path and an efficient algorithm is developed based on Dijkstra algorithm to search a reliability-energy disjoint path set. The simulation shows the proposed algorithm is effective and efficient.
