Many industrial and building automation systems use motion detectors to control different functions basedon human presence, such as lighting, for achieving higher efficiency of those functions by turning them offwhen not needed. Additionally, these systems require increasing numbers of wireless sensor nodes toreduce the installation costs and the make the systems more flexible for future expansion by eliminatingwiring. However, one of the major limitations for a large wireless network is power. Because thesesystems are battery powered, the maintenance cost associated with periodic battery replacement can　...
