Power-efficient Location-based Cooperative Routing with Sensor Power Upper Limit for Wireless Sensor Networks

Cooperative routing in Wireless Sensor Networks can improve performance in these types of networks. In our work, we propose a routing algorithm called Location-based Cooperative Routing with Sensor Power-upper-limit for Wireless Sensor Networks. The algorithm is based on the principle of minimum link power and aims to take advantage of nodes cooperation to make the link work well in Wireless Sensor Networks with a low transmission power. In the proposed scheme, with a determined sending power upper limit, nodes find the most appropriate next nodes and single-relay nodes with the proposed algorithm. Moreover, this proposal subtly avoids the nodes not working, because we add Bad nodes Avoidance Strategy. Simulation results show that, compared with other routing algorithm, the algorithm proposed in previous study, proposed algorithm with Bad nodes Avoidance Strategy can significantly improve the performance in reducing the overall link power, enhancing the transmission success rate and decreasing the retransmission rate.
