A Location-Based Power Conservation Scheme for MANETs
Hussein Al-Bahadili, Azmi Halasa · IGI Global eBooks · 2012
In a Mobile Ad Hoc Network (MANET), a mobile node consumes its power in message communication, message processing, and other operation missions. The amount of power a mobile node consumes for communication is the highest and the dominant as compared to what a node consumes for other tasks. The power consumed in communication is proportional to the square of the nodes’ radio transmission range (R); therefore, minimizing R contributes to a significant reduction in power consumption and consequently increases node battery-power lifetime. This chapter presents a description and performance evaluation of a new efficient power conservation scheme, namely, the Location-Based Power Conservation (LBPC) scheme. It is based on the concept of reducing R by utilizing locally available nodes’ location information to adjust R according to one of the three proposed radius adjustment criteria: farthest, average, and random. So that instead of transmitting with full power to cover up to its maximum radio transmission range (Rmax), the transmitting node adjusts R to less than Rmax, which provides a power conservation factor equivalent to (R/Rmax)2.
