【摘要】 该文提出适合多跳Ad hoc网络的支持MIM0的拓扑未知预约时分多址接入协议。通过预约,每个节点在其分配的无冲突时隙并行发送最大数据流,并以一定概率利用其分配时隙巾的冲突时隙和未分配时隙巾的卒闲时隙而发送一部分数据流。该协议不需知道全网拓扑结构,便于实现和分布式应用。通过理论分析推导出最小通过率及最佳帧长。结果表明该协议具有对网络拓扑的稳定性。更多还原

【Abstract】 A topology-transparent Time Division Multiple Access (TDMA) with reservation for MIMO link is proposed for multi-hop Ad hoc networks in this paper. By reservation each node transmits simultaneously all data streams in its assigned collision-free slots and utilizes free slots among other non-assigned slots and its assigned collision slots by probability to transmit a part of all data streams. The protocol is suitable for distributed application since it need not know the whole network topology information. Through theoretical analysis, the minimum throughput and optimal frame length are derived. The results show that the protocol is robust to topology change.更多还原
