为了提高无线传感器网络的能量有效性,该文在分析基于分簇的传统方案和协作分集数据传输方案的能量效率基础上,提出了一维传感器网络分簇多用户分集数据传送方案(CMDDTS)。理论分析表明能量开销依赖于数据融合比、簇内通信的发送功率、簇间通信的接收功率以及电路消耗的功率和簇内传感器的数目,仿真结果验证了所提方案的能量效率优于传统方案和协作分集数据传送方案。
On the base of analysis about energy efficient schemes for data transmissions including cluster-based traditional scheme and cooperative diversity, a communication scheme--cluster-based multiuser diversity data transmission scheme is proposed to improve energy efficiency of the wireless sensor networks. The theory analysis shows that energy consumption depends on data aggregation ratio, transmission power of intracluster communication, reception power of intercluster communication, the cost energy of circuit and number of sensors within a cluster. The simulation result verifies that the proposed communication scheme provides the best energy efficiency.
