Abstract :
One important issue that has to be taken into account in wireless devices is the energy conservation. Every infrastructureless network must be adaptively self configured particularly in terms of energy, connectivity, and memory. Efficient utilization of battery power is important for wireless users because due to their movements their energy is fluctuating at different levels during operation mode. Traffic plays a major role for energy consumption because of the unpredictable incoming-flow nature. This paper describes an adaptive method called adaptive dynamic caching energy conservation (ADCEC), which bounds an asynchronous operation where each node evaluates dissimilar sleep-wake schedules/states based on each node´s incoming sleep-history traffic. Simulation study is carried out for the energy conservation evaluation of the proposed model taking into account a number of metrics and estimation of the effects of incrementing the sleep time duration to conserve energy.
