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.
