无线令牌环协议（WTRP）是智能交通系统（ITS）无线网络中的一种介质访问控制（MAC）协议。它在有界延迟和预留带宽方面支持服务质量（QoS）。WTRP是有效的，因为它减少了由于碰撞而重新传输的次数。每个电台轮流播送，在播送一定时间后被迫放弃播送权，这是公平的。它是一种支持多种拓扑的分布式协议，因为并非所有站点都需要相互连接或连接到中心站。它可以与允许控制代理一起用于带宽或延迟预订。WTRP对单节点故障具有鲁棒性。WTRP设计用于从多个同时发生的故障中优雅地恢复。它在ITS专用短程通信（DSRC）和安全关键的车对车网络中的跨接入点协调方面有应用。
The wireless token ring protocol (WTRP) is a medium access control (MAC) protocol for wireless networks in intelligent transportation systems (ITS). It supports quality of service (QoS) in terms of bounded latency and reserved bandwidth. The WTRP is efficient in the sense that it reduces the number of re-transmissions due to collisions. It is fair in the sense that each station takes a turn to transmit and is forced to give up the right to transmit after transmitting for a specified amount of time. It is a distributed protocol that supports many topologies since not all stations need to be connected to each other or to a central station. It can be used with an admission control agent for bandwidth or latency reservations. The WTRP is robust against single node failure. The WTRP is designed to recover gracefully from multiple simultaneous faults. It has applications to inter-access-point coordination in ITS dedicated short-range communication (DSRC) and to safety-critical vehicle-to-vehicle networking.
