In this paper, the authors propose a novel Cluster Based Routing Protocol (CBRP) for prolong the sensor network lifetime. CBRP achieves a good performance in terms of lifetime by balancing the energy load among all the nodes. In this protocol first the authors Cluster the network by using new factors and then construct a spanning tree for sending aggregated data to the base station which can better handle the heterogeneous energy capacities. Simulation results show that CBRP can remarkably extend the network lifetime and amount of data gathered.
