摘　　要：近年来,物联网在智能家居领域中得到了广泛的应用,无线传感器网络(wireless sensor networks, WSNs)及ZigBee协议是基于物联网的智能家居系统中的关键支撑技术。在实际的应用过程中,现有的智能家居系统中感知层组网算法具有一定的局限性。为了提高智能家居感知层组网的实用性,论文提出了一种基于按键的广播入网算法,从而对底层ZigBee协议栈的入网方式进行了有效的改进,该算法在实际应用领域中有着较好的效果;同时,针对智能家居组网过程中协调器数据丢失的现象,论文在ZigBee协议的基础之上,提出了一种改进的基于非易失性存储器(NV)的存储算法,实验结果表明论文所提出的算法具有较高的可靠性,能够有效提高通信组网中的可操作性。In recent years,internet of things(IOT)has been widely used in smart home system.Wireless sensor networks(WSNs)and ZigBee protocols are key technologies in smart home systems based on internet of things.In the actual application process,the networking algorithm of sensing layer in existing smart home systems has certain limitations.To improve the practicability of the sensing layer network,this paper proposed a key-based broadcast networking algorithm and the efficiency of network access underlying ZigBee protocol stack was improved.Meanwhile,the coordinator is always unstable for storing data in real applications.In view of this problem,this paper,based on ZigBee protocols,put forward an improved non-volatile memory(NV)storage algorithm.The research results show that the proposed algorithm has high reliability and may effectively improve the communication network operability.
