In view of the deficiency such as huge energy consumption for intra-cluster communication

too much controlling expenses as well as volatile amount and unbalanced distribution of cluster-heads of LEACH protocol

a fixed partition routing algorithm based on energy balance is proposed. Combined with multi-hop algorithm to carry out uneven clustering strategy

intra-cluster communication energy consumption is effectively reduced without the problem of thermal region. By employing the idea of fixed partition

range and amount of cluster-heads node are significantly restricted. In addition

self-examination mechanism of cluster-heads energy is proposed to reduce controlling expenses. Meanwhile

energy and geographic locations information of node are fully taken into account in choosing optimal node to become cluster-heads. Simulation results demonstrate that this algorithm has outstanding performances in overall energy consumption

load balance

and lifetime of network.
