【摘要】 基于无线传感器网络受能量有限这一瓶颈因素的制约,为能进一步延长网络的生存周期,以节点设计为切入点,从微观方面对其能效进行了考究；从宏观角度,分析了 MAC 协议和路由协议在节能方面的设计策略,并对两者的制约机制对能效的影响进行了仿真和分析。更多还原

【Abstract】 As we know,the wireless sensor networks suffer the limitation of energy.In order to prolong further the lifecycle of the network,this paper focusing on the design of the nodes,discusses the energy-efficiency from the microcosmic aspect,and analyzes the MAC (Media Access Control) protocol and routing protocol’s design on economizing energy from the macroscopically aspect.Furthermore,analyzes and simulates the impact of the two protocols’ constraint mechanism on energy-efficiency.更多还原
