Therefore, it will suffer from some problems and challenges in wireless sensor network, especially the limited energy resource. This is because the nodes in sensor network often have no fixed power supply, and they maintain their power by batteries. If several sensors exhaust their energy, it leads to degradation of network life time. Thus, to develop energy-efficient communication infrastructure is a very important key technology of wireless sensor network. This research plan develops network topology-control technology to archive this objective. Our simulation results also show that it can efficiently lower the rate of energy consumption and increase the network life time by network topology control.application/pdf285445 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所無線感測網路拓撲控制技術能源消耗網路生命週期wireless sensor networktopology controlenergy consumptionand network lifetimereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/8045/1/932213E002122.pdf
