A novel framework of routing policy for energy-efficient wireless sensor networks: Progress-based nearest forwarding

抄録

A number of battery-driven sensor nodes are deployed to operate a wireless sensor network, and many routing protocols have been proposed to reduce energy consumption for data communications. This letter proposes a novel routing framework for multihop networks, which is based on transmission power control, nearest forwarding and packet progress toward a sink, in consideration of reducing the extra number of hops in the networks. The energy consumption for the topology employing the proposed forwarding is evaluated by simulation, and it is shown that the proposed scheme is more energy-efficient than the shortest-path tree constructed by Dijkstra's algorithm.
