| 摘 要： | 针对无线传感器网络中对通信实时性要求较高的应用环境,引入信道预约机制和反馈机制到S-MAC协议,提出了一种低时延的RF-MAC协议。该协议在有数据需要发送时先预约信道,各节点根据预约时间表进行数据传输。采用在数据传输过程中向源节点发送反馈信息的方法,实现后续数据的提前发送。通过仿真实验表明:RF-MAC协议有效地降低了数据传输的时延,同时改善了丢包率和网络吞吐量。

| Abstract: | Aiming at the high requirement of real-time communication application environment of wireless sensor networks,a low-latency reservation-feedback MAC(RF-MAC) protocol,which is based on channel reservation and feedback is proposed.In this MAC protocol,when a node is needed to send a data,a channel reservation message is firstly transmitted.Each node dispatches its data according to the reserved time list.The following data’s transmission is realized by using the method of sending feedback information to the source node during this process.Simulation results show that RF-MAC protocol has a good effect in reducing the data’s transmission latency of wireless sensor networks,and it also improves the packets’ loss ratio and the throughput of the network. |
