| 摘 要： | 为解决无线传感器网络中节点能量受限,文中提出一种基于有限反馈的协同M ISO传输方案,此方案通过接收端反馈给簇头节点的信道增益比值来调整簇头节点和协同节点的发射功率。通过联合优化传输速率和协同节点数,使得网络总能耗最小。分析和仿真结果表明,此方案能有效降低网络的总能耗。

| Abstract: | To solve the energy-constraint problem in Wireless Sensor Networks(WSNs),a limited feedback-based cooperative MISO(Multi-Input Single-Output) transmission scheme was proposed.In this scheme,Cluster Head(CH) adjusted the transmission power of CH and Cooperative Cluster Heads(CCHs) by employing limited feedback from the receiver.Transmission rate was jointly optimized as well as the number of CCHs in order to minimize the total energy consumption in wireless sensor networks.Analysis and numerical results show... |
