认知无线传感器网络中基于GSC的协作传输机制
Cooperative transmission scheme based on GSC for cognitive wireless sensor network
摘要
Abstract
In response to the features that the sensor nodes are energy-limited and power-constrained in wireless sensor network, a cooperative transmission scheme based on general selection combine(GSC) algorithm was proposed when the channel state information (CSI) was known to the transmitter. The number of cooperative nodes was depended on the GSC algorithm subject to a power constraint at the transmitter, and these selected nodes were scheduled according to the channel sate and individual residual energy. The analysis and simulation results show that the proposed scheme can effec-tively prolong the network lifetime.关键词
