摘要
针对功率不对称的无线传感器网络中网络寿命问题进行分析,通过数学分析与计算机辅助分析相结合的方法,分析得到了网络寿命与非对称情况的关系式。从节点的平均寿命的角度来看,网络的寿命会随着网络中节点的功率不对称的程度增加而减小。
In order to study the lifetime of wireless sensor networks, we construct a mathematic model of power asymmetric networks. Using this model together with computer, we draw the relationship between the power asymmetric condition e： the more asymmetric the power of the nodes, the shorter the expectation of the nodes＇ lifetime.
