In this paper, the authors propose a novel Tree Based Routing Protocol (TBRP) for prolong the sensor network lifetime. TBRP achieves a good performance in terms of lifetime by balancing the energy load among all the nodes. TBRP introduces a new clustering factor for cluster head election, which can better handle the heterogeneous energy capacities. Furthermore, it also introduces a simple but efficient approach, namely, fuzzy spanning tree for sending aggregated data to the base station. Simulation result show that, when compared other schema TBRP outperforms significantly in optimizing cluster heads energy consumption, amount of data gathered, and Improving system lifetime with acceptable levels of latency in data delivery.
