摘要
无线传感器网络对于环境数据采集和控制有着自身的优越性。在农业大棚的应用上,由于温室大棚形状狭长的特点,易引起网络节点剩余能量的不均衡,与电池的统一更换相矛盾。为了解决电池统一更换的问题,在通信协议方面运用了成簇算法与ADOVjr算法相结合的父亲树协议,通过建立中间簇头节点组织终端节点而形成数据传输网络,在簇头节点中加入了基于信任度函数的加权平均值递推的方法,实现了数据融合。在Matlab试验平台上的仿真结果表明,该设计能够有效提高网络节点剩余能耗的均衡性、消除失效节点引起的误差。该设计运用通信协议改良和新数据融合的方法,并在此基础上运用网关、服务器等最新的技术成果,使得物联网(IOT)温室大棚具有远程操作和管理的能力,提升了温室大棚的实用价值。
Wireless sensor networks have their own superiority for environmental data acquisition and control. In the application of agricultural greenhouse, due to the long but narrow layout characteristics of the greenhouse, imbalance of the residual energy of network may occur easily, which is conflict with the unified replacement of batteries. In order to solve this problem, for communication protocol, the father tree protocol based on the combination of integrated clustering algorithm and ADOVjr algorithm is adopted;and the data transmission network is formed through establishing the middle cluster head node to organize terminal nodes. In cluster head node, the method of weighted average recursion based on trust function is added, to implement data fusion. The results of simulation carried out on the Matlab experimental platform show that the network can effectively improve the residual energy balance of node and eliminate the errors caused by node failure. The design adopts the improved communication protocol and new method of data fusion;on this basis, the latest technological achievements of gateway and server are employed;this makes the IOT temperature controlled greenhouse has the capability of remote operation and management, and offer higher practical value.
