—Reducing the communication energy is essential to facilitate the growth of emerging mobile applications. In this paper, we introduce signal strength into location-based applications to reduce the energy consumption of mobile devices for data reception. First, we model the problem of data fetch scheduling, with the objective of minimizing the energy(More)

—The effective call admission control (CAC) scheme provides preferential treatments on call requests to achieve efficient utilization of system resources. The Markov Decision Process (MDP) is one of the optimization schemes used to derive the optimal CAC policy for predetermined goals. However, the MDP-based approaches suffer from the Curse of(More)
—Wireless Sensor Network (WSN) comprises of sensor nodes which are designed to sense the environment, transmit sensed data back to the base station via multi-hop routing to reconstruct physical phenomena. Since physical phenomena exists significant overlaps between temporal redundancy and spatial redundancy, it is necessary to use Redundancy Suppression(More)
