一种多机会确认的无线可靠广播机制
|
摘要
在无线网络中,控制命令的发布采用广播方式.为了提高广播业务的可靠性,针对传统的泛洪广播协议中没有确认机制,不能直接用于低时延、高可靠应用场景的缺陷,提出一种基于多机会确认的可靠广播机制.利用无线信道开放的广播特性和两跳邻节点路由信息,通过转发节点选择、监听转发、转发捎带及邻节点辅助确认4种方式,实现广播分组业务的可靠传输.NS2仿真结果表明,提出的多机会可靠广播机制,在降低广播业务传输开销同时,其递交率优于采用载波侦听机制的广播协议的递交率.
At the wireless network,the release of the control commands is broadcast.In order to improve the reliability of broadcast services,there was no acknowledgement mechanism in traditional flooding broadcast protocols and it could not be used directly in the shortcomings of low-delay and high-reliability application scenarios.A reliable broadcast transmission based on multiple opportunities acknowledgement was proposed.The mechanism used the broadcast characteristics of the open wireless channel and the routing information of the twohop neighbor nodes,and selected the forwarding node,forwarding monitoring,forwarding piggybacking,and neighbor node auxiliary acknowledgement opportunities.The mechanism could achieve reliable transmission of broadcast control packet services.NS2 simulation results showed that the multi-opportunity reliable broadcast mechanism proposed in this paper really reduced broadcast transmission overhead,and its reliability was better than the delivery rate of the broadcast protocol using the carrier sense mechanism.
