Abstract-Nowadays electricity is the prime source of energy around the world for domestic and industrial applications. Our lifestyle revolves around electrical appliances and devices which make it a core necessity. However there is a shortage of this very important source of energy, especially in country like Pakistan where the overall life and building pattern is highly energy inefficient. Furthermore, energy prices soar due to different reasons; more building owners and operators are turning to energy management to reduce their overall operating costs by using efficient and reliable energy management systems and techniques. Generally this is achieved by improving the energy efficiency of building systems and energy conservation. In this paper, an active node based wireless network is proposed and implemented for energy management in a typical Pakistani environment. The proposed system is primarily based on the assumptions that most of the energy is wasted unintentionally in domestic applications and industrial processes.Index Terms-Energy efficiency, energy management, wireless sensor network.
