【摘要】：無線傳感器網絡技術應用于精細農業(yè)信息獲取與管理已成為一種趨勢和必然,針對WSN在大規(guī)模農田種植監(jiān)測領域中所面臨的監(jiān)測面積大、監(jiān)測時間長、低功耗要求、地勢復雜以及作物多樣等問題,深入研究基于DEEC的等邊三角形節(jié)點部署的負載均衡成簇協(xié)議ETLB-DEEC(Equilateral Triangle Load Balancing-DEEC),采用等邊三角形網格節(jié)點部署方式與網絡分區(qū),提出"孤兒節(jié)點"和"收容節(jié)點"的概念。在此基礎上,設計一種面向基站最短路徑簇間多跳尋優(yōu)機制,可找尋多條最短路徑協(xié)議。仿真結果表明,改進的協(xié)議具備高效節(jié)省傳感器節(jié)點數(shù)、實現(xiàn)全局網絡負載均衡,提高網絡能量利用率,延長WSN整體生命周期等功能和特點。
[Abstract]:Wireless sensor network (WSN) technology has become a trend and necessity to obtain and manage fine agricultural information. In view of the large area, long monitoring time and low power consumption of WSN in the field of large-scale farmland planting and monitoring, wireless sensor network technology has been applied to obtain and manage fine agricultural information. Based on the complex terrain and crop diversity, the load balancing protocol (ETLB-DEEC (Equilateral Triangle Load Balancing-DEEC) for the deployment of equilateral triangular nodes based on DEEC is studied, and the deployment mode of equilateral triangular nodes and the network partition are adopted. The concepts of "orphan node" and "shelter node" are put forward. On this basis, a multi-hop optimization mechanism for the shortest path cluster of base stations is designed to find multiple shortest path protocols. Simulation results show that the improved protocol can efficiently save the number of sensor nodes, achieve global network load balance, improve network energy utilization, and prolong the overall life cycle of WSN.
