基于蓝牙散射网的无线传感器网络研究

为适应网络拓扑高度变化的无线传感网络,结合国内外蓝牙技术在无线传感器网络中的应用,提出并实现一个新型的基于蓝牙散射网的体系结构模型。蓝牙层使用改进的TPSF算法,通过限制桥节点度数减轻通信负载,并引入新的时间分配机制构建网络。新的体系结构模型不仅能满足传感器网络放置灵活、移动性强、自组织性和可扩展性高的要求,还大大减少了网络通信负载和时延,既能节省成本,又给用户提供方便的操作接口,具有很大的灵活性、可控性和可靠性。

Research on Wireless Sensor Network Based on Bluetooth Scatternet

In order to suit a high dynamic topologic wireless sensor network(WSN),summarize the using of bluetooth in WSN at home and abroad,presented and implemented a new WSN model based on bluetooth scatternet.On the base of revised TPSF algorithm,reduced the traffic load by limiting the degree of bridge node of net,and introduced the time slot scheduling mechanism.This new architecture not only accommodates the WSN's requirements of deposit flexible,better mobility,self-organization and expansibility,but also alleviates traffic load and net work delay.It has flexibility,controllability and reliability,saves cost and provides convenient operating interface.
