The building automation systems (BAS) include the monitoring and control of building services and networks. Since different manufacturers usually deal with one aspect of building automation such as heating ventilation and air conditioning, lighting control, different kinds of alarms, etc, the Final building automation system has different subsystems which are finally taken to an integrated building management system. The development of a prototype to be used in a wireless sensor network (WSN) which also integrates Digital addressable lighting interface (DALI) protocol can provide a solution for centralization of building automation services. Since DALI is a well-established standard and it has been adopted by major electronic ballasts’ suppliers it is very easy to find DALI compliant devices. Despite it is designed for lighting control, DALI has also been adapted to other applications, such as motor or fan controllers, proximity alarms, etc. Adapting the standard to a WSN allows integrating DALI devices as a part of the WSN, expanding the traditional DALI bus and removing wires, which results in a reduction of installation costs. For more efficient energy utilization of wireless sensor network, the IEEE 802.15.4 standard is modified to a deployable energy efficient 802.15.4 MAC protocol (DEEP).
