中文摘要

本論文中建議某些重要因素,來提高無線感測器網路(wireless sensor networks,WSNs)的能源效率、增加其感測資訊的準確率和延長其使用壽命(life-time)。基本上採取感測器管理的機制,包括感測器排列的序列,感測器佈署的安排。首先,有些參數會惡化感測器節點的使用壽命表現,例如感測的距離、路徑損失因素、傳送的位元數和傳送路徑遭受干擾等。在此,改變感測器佈署(deployment)的排列方式可以促進WSNs的壽命效能。根據模擬的結果明確地表示,在本研究論文中,所提出的方式不僅可以促進提高能源效能,還可以提高感測的準確性,而感測器節點的使用壽命也得到明顯延長。
ABSTRACT

In this paper some factors of analyzing to promote the energy efficient, increase the accuracy of sensing data and prolong the lifetime of sensor nodes for WSNs (wireless sensor networks) is proposed. On the basis of adopting sensor management includes sensor movement sequence and sensor location arrangement the issue of lifetime requirement for sensor nodes which deployed surround surveillance environment and the data fusion center are addressed too. First of all, the lifetime performance of the sensor nodes defeated by some parameters around the WSNs is illustrated. Such as, the sensing range, the path loss factor, the number bits of a transmitted packet, and the interference suffered in the transmission path etc.. Furthermore, the algorithm of sensor location arrangement is modified for the purpose of improving the lifetime performance in WSNs environments. According to the simulation results which definitely show that the proposed algorithm in this paper is not only to improve the energy efficient sufficiently, but the sensing accuracy and the lifetime performance of the sensor nodes are also obtained significantly promoted.
