摘要 针对无线传感器网络可靠性传输度量标准不够准确的问题,提出了基于包接收率模型的协作无信标可靠路由协议CBRR。CBRR充分利用无信标转发和协作通信的优势,完全避免冗余探测包的使用,并通过等待响应时间设定、协作节点概率保证以及冗余数据包发送等方式实现单跳数据传输的可靠性保证。仿真结果表明,CBRR协议不仅能够提供高可靠性支持,而且具有良好的传递成功率、传输延迟和能量效率。 Based on the packet reception model for real wireless links, a cooperative beaconless reliable routing protocol (CBRR) is proposed. CBRR provides a novel forwarding policy combining with conten- tion forwarding and cooperation forwarding, which can achieve the reliable guarantee between a single hop by the priority of waiting delay, cooperative probability guaranty and redundancy transmitting. Fur- thermore, CBRR can obtain packet reception rate through RTS-CTS handshake without using probing messages. Simulation results verify the validation of CBRR in term of its high reliability with better energy efficiency and shorter delivery delay.
