Wireless Sensor Networks (WSNs) consists of plenty nodes which are low cost, low power consuming, small volume and short-transmitting. As sensor nodes are deployed in sensing field, they can help people to monitor and aggregate data. Researchers also try to find more efficient ways of utilizing limited energy of sensor node in order to give longer life time of WSNs. Therefore, how to reduce node's energy that is consumed in transmitting data has became a very important issue. From many kinds of paper, multi-hop routing protocol is well known for power saving in data gathering. Recently researches uses such types of the cluster-based (e.g., LEACH), the chain-based (e.g., PEGASIS) and the tree-based (e.g., TREEPSI) to establish their energy-efficient routing protocol. In this paper, we propose tree-clustered data gathering protocol (also called TCDGP) to improve the LEACH and TREEPSI. The novel proposed protocol can preserve both advantages and improve the power consumption further. Finally, simulation results show that our proposal has better performance than before.
