無線感測網路(Wireless Sensor Networks)由許多小型、分散的節點所組成,通常可運用在軍事、醫療、環境觀測等方面。 然而這些節點有著許多限制,例如:有限的電量,運算能力以及傳輸範圍等等。 這些限制往往會造成整體無線感測網路的存活時間 (lifetime) 變得非常的短,譬如當感測網路中尚存在許多距離基地台較遠的節點、擁有充足的電力操作基本的功能,卻會因為其他的近區節點已經無法運作,導致資料無法傳回基地台(sink) ,造成整體無線感測網路喪失了功能。

在DREAM[1] 以及 SELAR[2] 兩篇論文中,作者分別利用方向性的選擇以及電量的高低因素,來決定傳輸的路徑,藉以改善整體無線感測網路的存活時間。

本篇論文基於上述的概念,提出更進一步的改進方法。 基本上,我們將節點分為兩種不同的角色與功能,並採用簡單的自我推舉演算法,以使得傳輸資料的電量負擔能夠更為平均,進而延長整體無線感測網路的存活時間。
Wireless sensor networks (WSN) consist of thousands of tiny low cost nodes and are used in applications such as military, hospital, environment observation of scientific research. However, these small devices have many restrictions like limited energy, computing capability, and transmission range, etc. Most of these restrictions may result in the short lifetime of the whole sensor network, which means that even though some nodes still have powers, the whole WSN may lose the function for collecting data.

Therefore, how to enhance the lifetime of wireless sensor network has become an important issue. In DREAM [1] and SELAR[2] papers, the authors utilize the geographic and power consumption factors for choosing transmission path to improve the lifetime of wireless sensor network.

In this paper, we propose some mechanisms for further improvement. Our approach will divide the sensor nodes into two different roles & functions, and adopt a simple self-election algorithm. Through these mechanisms, the total powers for transmitting data could be shared by most nodes, and the lifetime of wireless sensor network will be enhanced much better than SELAR[2].
