An Energy-Effective Routing Protocol Efficiently Constructs Cluster Topology for WSN

BACR is a new hierarchical routing protocol based on LEACH designed for WSN. It introduced energy-involved voting and back-off announcement to control the number of cluster-heads to vary within a small range and evenly locate the cluster-heads thus to prolong the network lifetime. This work also employed the technology of cluster reappointment to minimize the energy consumed in cluster set-up phase so as to extend the lifetime further. Experiments on MATLAB have proved this more effective than LEACH.
