無線感測網路近年來廣泛應用於生態環境監控，提供一個高密度的時間與空間的監測，此為傳統監控生態方式所不及的。因為感測節點能量上的限制，如何有效節能的將資料傳送到基地台，延長感測網路的網路生存期間是相關研究努力的目標。
本研究針對無線感測網路中的叢集式架構，提供一個優化的叢集決定方法，依據節點收到資料的能量，而決定叢集首的篩選機制，經由兩階段決定叢集，達到時間與空間的均勻性，各叢集中由一叢集首負責彙整資料，並傳送到遠處的基地台，加上配合CDMA以及TDMA機制，有效避免碰撞利用頻寬，由模擬結果得知此方法可有效延長網路生存時間。

In recent years, wireless sensor networks widely applied in the environment monitoring. It provides a high density the time and the spatial monitor. This is for traditional monitoring ecology way. How to conserve energy effectively transmits the data the base station and the extension sensing network's network lifetime is related the research the goal.
Prolonged network lifetime, scalability, and load balancing are important requirements for many sensor networks applications. Clustering sensor nodes are an effective technique for achieving these goals. Based on this approach, we propose an energy conservation communication protocol with a time and space based cluster-head selection mechanism. It periodically selects cluster-heads. Each cluster has on cluster-head to collect the data, and transmits data to base station. Our simulation results in much efficient energy consumption and compared with the LEACH
