In this paper, we develop a new framework to save the data processing energy and extend the operational lifetime of portable video communication devices. Video compression is computationally intensive and energy-consuming. However, portable video communication devices, powered by batteries, have limited energy supply for data processing. One of the central challenging issues in portable video c...

Due to the inventions in technology, Wireless sensor networks have been growing rapidly. Sensor nodes are capable of performing some processing, gathering required information and communicating with other connected nodes in the network. Sensor nodes are of limited energy which is a drawback during peak times in a network. Always energy is of primary concern in a wireless sensor networks. There ...

The demand for Wireless Sensor Networks (WSN) has motivated the researchers to obtain energy optimized solutions, because of the constraint on the limited use of energy in these networks. In WSN, apart from energy optimization there are many other areas such as, coverage of the target area and the connectivity of the network for data routing, which attract the attention of researchers for optim...

sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...

As society develops, energy needs and the warnings of global warming have become main areas of focus in many areas of human life. One such aspect, the building sector, needs to take responsibility for a significant portion of energy use. Researchers need to concentrate on applying innovative methods for controlling the growth of energy use. Apart from improving energy efficiency by reducing ene...
