Abstract

Due to a low installation cost of communication infrastructure, Low Power Wireless Area Networks (low PAN) presents an efficient solution for home and building automation. The low PANs operate in a microwave radio band that is often shared by several home appliances. Laptops, wireless routers, cordless phones and microwave ovens occupy the 2.4 GHz band without any channel allocation and thus interoperability with the low PAN systems presents a significant challenge. Therefore, we have performed several laboratory experiments to study the coexistence of low PAN devices with WiFi equipped laptop, WiFi router and microwave oven. The performance evaluation was based on a measurement of Packet Delivery Ratio (PDR) metric. Results shows that presence of the home appliances in the low PAN environment significantly affects the low PAN communication efficiency. Furthermore, we have deployed Zigbee based wireless network in the home environment to study the communication performance in area perturbed by common home radio interferences and obstacles. The lessons learned from network deployment are also presented within the paper.

家用微波器具在实验室和家庭环境下的低pan网络共存测量

由于通信基础设施的安装成本低，低功耗无线局域网(low PAN)为家庭和楼宇自动化提供了一种有效的解决方案。低pan工作在一个微波无线电波段，通常由几个家用电器共享。笔记本电脑、无线路由器、无绳电话和微波炉占用2.4 GHz频段，没有任何信道分配，因此与低PAN系统的互操作性提出了重大挑战。因此，我们进行了多次实验室实验，研究低PAN设备与配备WiFi的笔记本电脑、WiFi路由器和微波炉共存的问题。性能评估是基于数据包传输率(Packet Delivery Ratio, PDR)度量。结果表明，低PAN环境中存在的家用电器对低PAN通信效率有显著影响。此外，我们还在家庭环境中部署了基于Zigbee的无线网络，以研究受常见家庭无线电干扰和障碍物干扰区域的通信性能。本文还介绍了从网络部署中获得的经验教训。
