In this paper, we investigate the optimal packet scheduling problem in a two-user multiple access communication system, where the transmitters are able to harvest energy from the nature. Under a deterministic system setting, we assume that the energy harvesting times and harvested energy amounts are known before the transmission starts. For the packet arrivals, we assume that packets have already...
Energy minimization in wireless sensor networks is a key issue, particularly in order to maximize the lifetime of nonserviceable battery powered devices in the field. In this paper, we propose a new energy consumption model that allows allocation of variable transmit power and data compression/transmission rate to each sensor node. In contrast to previous work, our model captures both the cost of...
