摘要：

为了在多跳Ad hoc网络中提供实时业务和尽力而为业务的区分服务，提出了一种支持区分服务的媒体接入控制(MAC)机制――支持区分服务的标签交换分布式协调功能(DL-DCF). 在MAC层通过标签获取转发信息并携带在请求－应答帧(RACK)中发送，触发下游节点的清除发送帧(CTS)握手，使得数据包多跳连续转发；连续转发概率根据业务类型和节点数据包队列占用率确定，实现了区分服务，避免了节点队列溢出. 仿真结果表明, 与802.11 DCF相比，在重负载条件下DL-DCF能够显著降低端到端时延和归一化控制负载，提高网络吞吐量，实现区分服务.

Abstract:

In order to differentiate real-time traffic from best-effort traffic in multi-hop Ad hoc networks, a new differentiated medium access control (MAC) scheme, differentiated label-swiching distributed coordination function (DL-DCF) is proposed. Forwarding information is obtained by label in MAC layer and is piggybacked in Request-acknowledgement (RACK) frame. Clear to send (CTS) handshake of the downstream node was triggered by RACK that made the data frame transmit consecutively across multi-hop. The probability of performing consecutive transmission is calculated according to traffic type and occupied ratio of the higher layer data buffer in MAC layer that can realize service differentiation and avoid data buffer overload. Simulation shows that compared with 802.11 DCF , under high loads, DL-DCF can remarkably decrease the end-to-end delay and normalized control overhead, increase the throughput, and realize service differentiation.

Key words: medium access control scheme, differentiated label-swiching distributed coordination function, differentiated service, consecutive transmission, label switching
