【摘要】：针对基于煤矿安全监测的Zig Bee网络中数据传输的特点,对Zig Bee原有路由算法进行改进,提出了一种多路径路由协议。在协议中,重点考虑煤矿发生突发事件时大量紧急数据的传输问题,在事发节点与协调器节点之间建立多条路径并发地传输数据,提高数据的传输速率和可靠性,并且在寻找多条路径时,只将RREQ分组转发给父节点或者满足能量和广播半径要求的网络深度更低的邻居节点。仿真结果显示,改进后的路由协议在数据量大、发包速率更快的情况下表现出更优的性能,满足煤矿安全监测的要求。
[Abstract]:According to the characteristics of data transmission in Zig Bee network based on coal mine safety monitoring, the original routing algorithm of Zig Bee is improved, and a multipath routing protocol is proposed.In the protocol, the transmission of a large number of emergency data in coal mine emergencies is considered, and multiple paths are established between the accident node and the coordinator node to transmit the data concurrently, so as to improve the transmission rate and reliability of the data.When searching for multiple paths, only the RREQ packets are forwarded to the parent nodes or neighbor nodes with lower network depth that meet the requirements of energy and broadcast radius.The simulation results show that the improved routing protocol has better performance and meets the requirements of coal mine safety monitoring under the condition of large amount of data and faster outputting rate.
