摘　　要：针对无线多跳自组织网络由于结构缺陷所造成的生存周期短的问题,提出了一种延长该网络生存周期的方法。通过在圆形区域内搜索中间节点,以2跳数据转发代替原有的1跳转发过程,在降低源节点发送功率的同时减少整个转发过程的能量损耗。公式推导验证了方法的可行性,通过MATLAB仿真对整个传输过程的节能效果进行分析,并给出了方案实施的流程图。Multi-hop wireless self-organizing network has structure defect which gives rise to short lifetime. This paper puts forward lifetime prolonging methods for multi-hop wireless self-organizing network to overcome this defect. Through searching intermediate node in circular area which changes one-hop data forwarding into two hops, the sending power of originating node and the energy loss in the process of data-forwarding can be reduced. Firstly, the feasibility of methods is proven by formula derivation. Secondly, the energy-saving effect of transmitting process is analyzed by the simulation of MATLAB. Finally, the flow chart of the scheme implementation is given.
