摘　　要：针对能量与计算能力受限的无线传感器网络因干扰引发能耗增加、网络生命期降低的问题,提出了联合功率控制与信道分配的生命期优化博弈算法——LOAPC。LOAPC探索节点功率与剩余能量对节点干扰的影响,构建干扰影响度量模型,并引入期望传输次数,建立新颖的节点生命期模型。最后,LOAPC以降低干扰与延长生命期为优化目标,以既保证网络连通又降低能耗功率作为可选功率集合,达到延长网络生命期的效果。仿真结果表明,所提算法具有低干扰、低能耗并有效延长生命期的特性。Due to the problem of shortening the network lifetime which was caused by the big energy consumption for wireless sensor network (WSN) whose energy and computing power was limit, a lifetime optimization game algorithm combined power control and channel allocation (LOAPC) was proposed. The influence of node power and residual energy on the node interference was explored to construct an interference affection measurement model. Then, expected transmission times was introduced to establish a novel node lifetime model. Finally, LOAPC aimed at reducing interference and prolonging lifetime, and the node power was limited by an optional power set which ensured the network connectivity and economized energy consumption, so as to prolong the network lifetime effectively. At the same time, the simulation results show that the algorithm has the characteristics of low interference, low energy consumption and effectively prolonging the lifetime of the network.
