基于改进ZigBee路由算法的智能家居控制系统

The Control System of Smart Home Based on Improved Zig Bee Algorithm

为实现智能家居远程控制,指令将经路由器转发至Zig Bee协调节点,并通过Zig Bee网络实现设备的控制。因Cluster-tree算法传输时延长,损耗大,对树型拓扑发现和地址分配机制进行了优化,通过定义组别,选择合适节点作为中继节点。若目的节点为源节点的邻节点,则将数据传送至目的节点,否则创建目的节点的组别,选择合适的中继节点。仿真表明,当节点数越多时,改进的算法可减少30%的能耗,并随时间的增长,死亡节点数将降低10%,有效地均衡了网络负载。

To realize the remote control of the smart home,the order will be forward to the ZigBee coordinator node, then the ZigBee network will control terminal equipment. As cluster-tree algorithm easily leads to increased transmission delay,and the route loss is too large,therefore,the original algorithm is improved：a tree network topology discovery and address allocation mechanisms have been optimized. Through defining a group of nodes,we will select the appropriate node as a relay node from those nodes. If the destination node belongs to an adjacent node of the source node,then the data can be directly transfered to the destination node,otherwise you must first create the relevant constituencies of the destination node,then select the appropriate relay nodes,The Simulation results show that when the more number of nodes increasing,the improved algorithm can reduce 30%energy consumption,along with the time,the number of death nodes will effectively reduce 10%,then it will balance the network load effectively.
