智能楼宇中无线传感网混合接入设计

本文针对智能楼宇环境,设计并实现无线传感网络、电力线载波网络和以太网接入的混合网络。文中的混合网络中,无线传感网络在频域和空域上分割子网,并在每个子网的接入节点进行了分布式判决。电力线载波网络将各个无线传感网进行连接,并通过以太网接入节点将信息采集并发送至Internet。本设计在保留了无线传感网优点的前提下,利用了现有电力网络布线设施,并且满足远程监控要求,同时解决了无线传感网随着节点数目增多而信号连通性急剧下降的问题。使得智能楼宇环境中组建大型无线传感网络成为可能。

Mixed structure sensor network and internet access method in intelligent buildings

This paper proposes a wireless sensor network access system basically to be applied in intelligent buildings,which is a combination of the wireless sensor networks,the power line carrier networks and the Ethernet.The proposed system subdivided the wireless sensor network in both the frequency domain and spatial domain,and carried out distributed decision at every sink node.Taking advantage of wireless sensor networks,the proposed system utilizes the power line communication nodes interconnect to to meet the needs of the remote monitor,which overcome the problem the that connectivity decreases rapidly when the wireless sensor network becoming large.The proposed system makes the application of large scale wireless sensor network in intelligent buildings possible.
