摘要
针对无线传感网中紧急信息因网络拥塞、节点负荷过重等因素而无法被及时传输和处理的问题,提出一种可靠的传输协议。该协议将信息组装成帧,将其加入相应的队列,由队列调度模块直接调用网卡驱动接口发送数据,并引入确认重传机制。仿真结果表明,该协议降低了网络负荷、减少了资源的消耗、保证了紧急信息的可靠传输。
A reliable transmission protocol is proposed for wireless sensor networks because of the fact that the emergency information is unable to be transmitted and processed in time due to network congestion and overload of nodes. The protocol assembles the information into a frame and adds it to the corresponding queue. It sends the data directly by the queue management module, and introduces the confirmation retransmission mechanism. Simulation results show that the protocol reduces the network load, reduces the consumption of resources and ensures the reliable transmission of emergency information.
