基于Zigbee-WiFi的异构无线传感网实时数据融合机制研究

Real time data fusion mechanism of Zigbee-WiFi based heterogeneous wireless sensor network

研究了IEEE 802.15.4 Zigbee协议及IEEE 802.11b WiFi协议,基于Zigbee-WiFi的媒体接入控制层(MAC),设计了一种具有Zigbee与WiFi协议转换的网桥,同时引入数据重组转发的概念,实现了Zigbee无线传感网与WiFi传输通信的异构融合.仿真结果表明,融合的网络的服务质量相对于非异构网络有很大提高.

This research focuses on the IEEE 802. 15.4 Zigbee and IEEE802. llb WiFi protocol, and based on Zigbee -WiFi media access control layer （MAC） , it designs a Zigbee -WiFi protocol conversion bridge, with the introduction of the concept of forwarding data restructuring to achieve a Zigbee wireless sensor network transmission communication with WiFi heterogeneous integration. Finally, the simulation results show that the converged network quality of service with respect to non - heterogeneous networks has greatly improved.
