摘　　要：基于TDMA的战术Ad Hoc网络,提出一种分布式的资源预约机制,其中收/发节点采用协商的方式预约时隙,邻居节点通过侦听方式获得时隙被预约的信息,然后依托该机制提出一种QoS路由协议,该协议能够在网络节点之间选择一条满足QoS要求且相对短的路径进行预约时隙,同时对于网络拓扑变化引起的链路故障也能局部修复。仿真表明该协议具有开销小和可靠性高等特点,能够提高战术Ad Hoc网络的QoS保障能力。Based on TDMA-based tactical Ad Hoc networks, a distributed resource reservation scheme is pro- posed, in which the sender node and the receiver node reserve time slots by means of handshake and neighbor nodes get the information of reserved time slots by means of interception. Then a QoS routing protocol is proposed based on the reservation scheme above,which can reserve time slots in a shorter and enough resource＇s path and locally repair the link failure caused by the topology variety. The simulation results show that the protocol has the characteristic of the low overhead and the high reliability and can improve the QoS capability of tactical Ad Hoc networks.
