摘要
分析了分簇结构无线传感器网络中随机功率控制的成功通信概率,并提出由网络对成功通信概率的要求来决定簇内通信时节点发送功率的最大值和最小值。仿真数据表明,在节点密度较高的分簇结构无线传感器网络中,随机功率控制与固定功率控制相比,有更高的能量效率。
Transmission successful probability of the random power control approach for clustered wireless sensor networks is analized in this paper. The minimum and the maximum of transmission power during the intra-cluster communication can be choiced to meet the transmission successful probability requirement of networks. The simulation results show that random power control can improve the energy efficiency compared to the conventional fixed power control in clustered wireless sensor networks where sensor nodes are distributed densely.
