针对智能家居网络系统，对家庭内部网络进行设计。对以数据为中心的定向扩散路由算法进行改进，将节点按房间的顺序规划在不同的矩形区域，每个矩形区域设立一个源节点，用来接收网关节点发布的消息。同时，研究了短时延情况下不确定时延网络控制系统的稳定性，并利用Lyapunov函数和线性矩阵不等式( LMI)方法，给出网络控制系统渐进稳定的充分条件。仿真结果显示，改进算法可延长网络生命周期，节省能耗，提高网络能效。

For smart home network system, the interior network of home has been designed. The directed diffusion routing algorithm with data as the core is improved, the nodes are arranged in different rectangular areas according to the sequencing of the rooms;a source node is set up in each rectangular area to receive the messages released from gateway. In addition, the stability of uncertain delay network control system under short time delay is researched. The sufficient condition for network control system asymptotic stability is given by adopting Lyapunov function and linear matrix inequalities ( LMI) . The results of simulation show that the improved algorithm extends the life cycle of the network, increases energy efficiency of network, and reduces energy consumption.
