摘要
协同分集是一种新近提出的空域分集技术,它使得终端之间可以共享彼此的天线,为实现多输入多输出(MIMO)提供了有效的方式,适合用于无线Ad hoc网络和无线传感网络中,成为研究热点。在分析协同分集技术的基础上,针对无线传感网络的特点,分析了传感网络中多跳路由算法与协同分集路由算法,给出网络的等效信道模型,并由此讨论使用协同分集对网络能源消耗的影响,讨论了基于协同分集的无线传感网络的实现。分析结果表明,协同分集在无线传感网络中具有较好的应用价值。
Cooperative diversity is a new space diversity technology that enables two terminals to share antennas and provides an efficient approach to MIMO. It can be used in ad hoc networks and wireless sensor networks. Multi-hop routing and cooperative diversity routing algorithm in WSN are analyzed, and equivalent channel models and energy analysis are given. Some problems in achieving cooperative diversity in WSN are discussed, and the results show that cooperative diversity has a valuable application in WSN.
