铁路沿线线性无线传感器网络路由协议研究
Research on Routing Protocols for Linear Wireless Sensor Networks along Railway Lines
摘要
Abstract
Monitoring objects along the railway line are in large number and scattered widely.In order to transmit the data collected by the sensors to the monitoring center, a wireless sensor network consisted of sensor nodes, sideway sink nodes, sink nodes and relay nodes is designed.In this paper, a routing protocol is designed to solve the routing problem in transmitting data between sideway sink nodes and sink nodes.Due to different importance level of the monitoring data from the sensors along the railway, data packets are sorted by priorities according to their importance.In designing this routing protocol, network lifecycle and data priority are considered.The packet forwarding model and packet queuing model are established to maximize the number of packets transmitted within network lifecycle.With balanced network energy consumption, two ways are used to reduce the delay of the high priority data packets:one is to reduce the forwarding of packets with high priority and the other is to reduce the queuing of packets with high priority.Simulation results show that this routing protocol can effectively reduce the transmission delay of high priority packets, balance the network energy consumption and improve the network lifecycle.关键词
