Ring and clustering routing strategy based on data filed in sensor network

In order to improve the energy efficiency and avoid the energy hole problem in wireless sensor networks, this paper proposes a routing algorithm named RCBDF (Ring and Clustering Based on Data Filed). The algorithm uses the concept of physical field and the ring network. The routing algorithm will achieve a better balance between energy consumption and network life by accounting the rate of the node remaining energy and the size of the cluster. Meantime, double cluster head rotation was introduced to cluster in this algorithm. Simulation analysis shows that: the routing policy will balance the energy consumption of the network at a large extent, greatly extend the network lifetime and avoid the energy hole phenomenon.
