Summary:

 

As wireless services and products continue to grow develop and  more and more capabilities such as multimedia, QoS, security and bandwidth. Low-power design remains one of  the most important research areas within wireless communication.

 

There has been a lot of research focusing presently on decreasing the amount of energy consumed by the wireless network interface.  Power conservation has typically been considered at the physical layer. However, most of the energy savings at the physical layer have already been achieved or we do not have a lot of room for improvement. Therefore, the key to energy conservation in wireless communications lies within the higher levels of the wireless protocol stack, like the . This paper describes research completed at the data link, network, transport, OS/middleware, and application protocol layers that have addressed energy.

Low Power design of the Entire Network Stack is needed to enhance energy efficiency. However, power conservation within the wireless protocol stack remains a very crucial research area for the viability of wireless services in the future.
