ABSTRACT
Traditionally building automation systems are realized through wired communications. However, wired automation systems require expensive communication cables to be installed and regularly maintained and thus are not suitable for many retro fit applications of sensor technologies [1, 2]. For example, the installation cost of a light switch in a
In particular, the use of wireless technologies offers distinctive advantages in the field of home and building automation [3-5] as installation costs are significantly reduced since no cabling is necessary, and neither conduits nor cable trays are required. Wireless technology also allows the placement of sensors where cabling is not appropriate for aesthetic, conservation or reasons of safety [4, 5].
