摘要: ZigBee的树形网络层结构在高可靠性和低功耗方面优于星型和网状结构,但在传输有潜在攻击的情况下,树形结构存在命令包和数据包传输无法统一的问题。为此,采用信号功率对比的方法,自动添加父子节点形成树形拓扑结构,并完成数据包传输的建模。实验结果表明,该方法可解决命令包和数据包传输可能面临冲突的问题,实现从拓扑结构的形成到数据传输的一体化。

Abstract: ZigBee’s tree topology shows better performance in reliability and power consumption than star and mesh topologies in network layer. However, the command and data packets may be inconsistent in tree structure under potential attacking situation. The proposal model which is used by signal-power-comparison method can add parent-child node automatically to form tree topology and transport data packets successfully. Simulation results show that the model can effectively solve confliction between command and data packets, and provide integrate and expandable flow from topology building to data transmitting.

Key words: Wireless Sensor Network(WSN), transmission model, parent-child node, sensor node, router node, coordinator node
