In this paper, a home Internet-of-Things system is analyzed by dividing it into four layers, i.e., the node layer, gateway layer, service layer, and open layer. The gateway layer, which supports a variety of wireless technologies and is the core of home wireless networks access unit, together with the node layer constitutes the home wireless network. A gateway prototype following the proposed architecture has been implemented. A testbed of an interference-aware wireless network which includes the gateway prototype has also been created for testing its user interaction performances. The experimental results show that both Wi-Fi and Bluetooth have an impact on the ZigBee communication. Considering the complex scene of home and building, ZigBee multihop communications are set to reduce the packet loss probability. In addition, an event-level-based transmission control strategy is proposed, in which the packet loss probability of wireless network is reduced by controlling the transmission priority of different levels of monitoring events, and optimizing the ZigBee wireless network channel occupancy.

用于家庭监控和性能评估的干扰感知无线网络


本文将家庭物联网系统分为节点层、网关层、服务层和开放层四层进行分析。网关层支持多种无线技术，是家庭无线网络接入单元的核心，与节点层共同构成家庭无线网络。遵循所提出的架构的网关原型已经实现。还创建了一个包含网关原型的干扰感知无线网络测试平台，用于测试其用户交互性能。实验结果表明Wi-Fi和蓝牙均对ZigBee通信产生影响。考虑到家庭、楼宇等复杂场景，设置ZigBee多跳通信，降低丢包概率。此外，提出了一种基于事件级别的传输控制策略，通过控制不同级别监控事件的传输优先级，优化ZigBee无线网络信道占用，降低无线网络丢包概率。
