توضیحات
An increasing number of home automation systems using wireless devices compete for the
radio access in the same space and time. Lately, a stressing trend consists of aggregating home
automation systems to save energy consumption, while at the same time avoiding wireless interference. This article proposes virtualization, open software deployment, and separation of radio and higher layers as the response to the increasing expandability of home automation systems combined with the increasing number of technologies
for connecting wireless devices. A system has been developed, containing three different technologies: ZigBee, Idsecom, and 6LoWPAN simultaneously working over a virtualization platform with access to a common antenna. The evaluation tests performed on the system validate the solution and separately show the performance
capacity of virtualization platform, software(ZigBee, Idsecom and 6LoWPAN) nodes, and 802.15.4 wireless antennas
Introduction
The atomicity of the Internet of Things (IoT) has arisen to handle energy efficiency and adaptability
requirements, as well as interoperability, scalability, and extendibility challenges. In home automation systems (HASs), this atomicity has brought a high number of gateways permanently connected to the electrical current and competing for the radio access. The competition will dramatically rise with the introduction of Thread, which is an incoming technology for HAS applications based on the 6LoWPAN protocol created by outstanding technological companies coordinated by Google Inc. Thread is called to compete with ZigBee and Z-Ware (popular in the United States), but at the same time, they will coexist together in many spaces, creating cross-technology interference. The cross-technology interference in the so-called unlicensed spectrum range is an old research problem, which is only partially solved thanks to, among others, dynamic channel selection. A good survey for understanding the
problem of cohabitation of different technologies was presented by Yang, Xu, and Gidlund in
