【摘要】：針對基于煤礦安全監(jiān)測的Zig Bee網絡中數(shù)據(jù)傳輸?shù)奶攸c,對Zig Bee原有路由算法進行改進,提出了一種多路徑路由協(xié)議。在協(xié)議中,重點考慮煤礦發(fā)生突發(fā)事件時大量緊急數(shù)據(jù)的傳輸問題,在事發(fā)節(jié)點與協(xié)調器節(jié)點之間建立多條路徑并發(fā)地傳輸數(shù)據(jù),提高數(shù)據(jù)的傳輸速率和可靠性,并且在尋找多條路徑時,只將RREQ分組轉發(fā)給父節(jié)點或者滿足能量和廣播半徑要求的網絡深度更低的鄰居節(jié)點。仿真結果顯示,改進后的路由協(xié)議在數(shù)據(jù)量大、發(fā)包速率更快的情況下表現(xiàn)出更優(yōu)的性能,滿足煤礦安全監(jiān)測的要求。
[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.
