摘要 介质访问控制(MAC)协议是无线传感器网络研究领域的基础协议和支撑技术.因此,一种能量高效的MAC协议是提高整个无线传感器网络能量效率的基础.针对无线网络中能量储备有限的特点,在分析了现有无线传感器网络节能协议的基础上,提出了一种能量高效的MAC协议.通过动态调整占空比和消除边界节点等方式,提高了无线传感器网络的能量效率,延长了网络的生命周期. Medium access control (MAC) protocol is the basic protocol and technique in wireless sensor networks (WSN).So an energy efficiency MAC protocol is the base of an energy efficiency wireless sensor network. Energy limited is the main characteristicness of WSNs. By refering to the classcal energy efficiency MACs, an improved scheme is putted forward. Using methods of dynamically adjust the Duty Cycle and avoid the boundary node, the new scheme can increase the energy efficiency of WSN.
