| 摘 要： | 为了较好地提高控制信息的利用效率,提出基于时分多址(TDMA)的令牌时隙媒介访问控制(MAC)协议. 该协议采用控制信道与数据信道分离的方法,在控制信道按照网络节点的标号(ID)顺序,动态拥有令牌时隙,及时交换节点信息参数及数据传输请求;在数据传输信道采用预约分配的时隙进行高速数据传输,避免了节点间的传输干扰. 同时采用空分复用TDMA模式,极大地提高了有限信道资源的利用率. 仿真结果表明,设计的MAC协议能够有效地提高网络的吞吐量,满足不同服务质量(QoS)和传输时延的要求.

| Abstract: | The medium access control(MAC) protocol is also important for airborne Ad hoc network in order to reduce time division multiple access(TDMA) overhead, increasing TDMA throughput, and decrease end-to-end delay. Our proposed token slot scheduling described in this paper allow the exchange of control information in an efficient and contention free manner such that each participating node can, in real time, converge to a consistent TDMA schedule. The dynamic resource needs of participating nodes can be rapidly accommodated for quality of service (QoS) guarantees. The scheduling algorithms are topology independent and require the nodes states to assignment right slot to each node in order to adapt to changing wireless network topologies dynamically. |
