提出了一种无线Ad hoc网络中基于跨层设计的同步动态令牌协议(CLSDTP)。采用了一种新的快速令牌传输机制,能很好的适应网络拓扑变化。提出了一种信道接入冲突避免算法,在单信道条件下较好的解决了暴露隐藏终端问题,大大提高了空间复用度。实现了路由协议和MAC协议的信息共享,大大压缩了系统开销,解决了使用表驱动路由的开销问题和路由信息交互的时效性问题,使得路由机制能更好的响应系统拓扑变化。
This paper proposes a synchronous dynamic token protocol (CLSDTP) based on cross-layer design in wireless Ad hoc networks. Adopts a new fast token transfer mechanism, which can well adapt to changes in the network topology. A channel access collision avoidance algorithm is proposed, which solves the problem of exposing hidden terminals under single-channel conditions and greatly improves the space reuse. It realizes the information sharing of routing protocol and MAC protocol, greatly reduces the system overhead, solves the problem of using table-driven routing overhead and timeliness of routing information exchange, and makes the routing mechanism better able to respond to system topology changes.
