基于分簇的传感网虚拟MIMO协议

A Cluster-based Virtual MIMO Protocol for Wireless Sensor Networks

提出一种应用于无线传感网的新型分簇式虚拟MIMO协议。协议基于簇头轮换,避免大量重新分簇带来的拓扑维护开销,从而提高网络能量效率。在簇间路由中,提出一种新型的"跨跳"操作,以平衡网络中不同节点与簇的能耗和生命周期。仿真实验结果表明,该协议较现有的的虚拟MIMO在能耗总量和均衡上均具有更好的效果。

This paper proposes a novel cluster-based virtual MIMO protocol for wireless sensor networks. The protocol adopts cluster-head rotation to avoid massive re-clustering energy waste as well as improving energy efficiency of the entire network. In the inter-cluster routing,a new operation named ＂over-jump＂is introduced to make energy consumption and lifetime balance among different nodes. The simulation results show that the proposed protocol is more effectively in energy saving and balance,compared with traditional cluster-based virtual MIMO systems.
