| 摘 要： | 针对分簇无线传感器网络WSN(wireless sensor networks)中现有的协同传输方案以牺牲频谱利用率来换取能效增益的不足,提出了一种基于叠加编码的簇间协同传输方案.该方案在保证系统的频谱利用率条件下,通过相邻簇的簇头节点相互协作来完成数据的传输.在频谱利用率相同的条件下,对现有的簇内协同传输方案和提出的...

| Abstract: | In the existing cooperative transmission scheme,the spectrum efficiency is dropped for higher energy efficiency.A cooperative inter-cluster scheme based on code superposition was proposed to improve the energy efficiency without decreasing the spectrum efficiency.The total energy consumption of the inter-cluster cooperative scheme and that of the proposed scheme with the same spectrum efficiency were analyzed.Theoretical analysis and simutation results show that the proposed scheme can obtain higher energy ... |
