| 摘 要： | 能耗开销是无线传感器网络(WSN)性能的瓶颈问题之一,而功率控制是解决这一问题的最有效方法。针对超宽带(UWB)WSN,该文以实现网络功耗最小化为目标,从跨层优化的角度提出了基于UWB最优功率分配策略模型;然后,给出了在lexicographic max-min(LMM)策略下的线性规划求解方法。仿真结果表明,LMM策略可较大改善节点平均功耗和链路成功接通率。

| Abstract: | Energy consumption is one of the key problems on the performance of wireless sensor networks(WSN) and power control is the most efficient way to work out this problem.This paper studies the ultra wide band(UWB) based WSNs and presents a clustered global optimization power assignment model.Aimed at minimizing the network power consumption,a solving method using LP under lexicographic max min(LMM) strategy has been developed.Simulation results show that average power consumption and the probability of activating link access can be improved by the proposed LLM strategy. |
