摘要

针对Ad Hoc网络和MIMO的有效结合

提出了适于多跳Ad Hoc网络的支持MIMO的分布式拓扑未知时分多址接入协议.该协议通过有限域无线网络设计算法在每帧给每个节点分配时隙且无需知道全网拓扑信息

这极大地减小了收集全网拓扑信息的开销.通过预约

每个节点在其分配的无干扰时隙并行发送MIMO链路的所有数据流

并在与其他节点共享的时隙发送MIMO链路的一部份数据流来解决传输冲突.同时推导出保证通过率和最佳帧长.结果显示动态分配MIMO的传输容量和抗干扰能力会极大地提高通过率.

Abstract

To effectively combine ad hoc networks with multiple input multiple output (MIMO)

distributed topology-transparent schedule for time division multiple access (TDMA) protocol with MIMO links in multihop ad hoc networks is proposed.By Galois Radio Network Design (GRAND)

the protocol assigns each node slots in each frame and need not know the whole network topology information

thus the overhead to collect topology information is greatly reduced.By reservation each node simultaneously transmits all data streams in the MIMO link in its assigned interference-free slots and utilizes its shared slots with other nodes to transmit a part of all data streams in the MIMO link to resolve collisions.The guaranteed throughput and optimal frame length are also derived.Results show that the network throughput will be improved greatly by dynamically allocating MIMO transmission capacity and its anti-interference ability.
