The topology of wireless sensor networks (WSNs) can be controlled through changing the transmission power of each node. We propose an adaptive energy efficient topology (AEET) algorithm where each node adaptively adjusts its transmission radius by l
Abstract—Energy efficiency is of great importance in wireless sensor networks, where each node is typically powered by battery with limited energy supply. In this case, cooperative broadcasting plays a significant role in saving transmission power c
In this paper, we study the resource allocation algorithm design for multiuser orthogonal frequency division multiplexing (OFDM) downlink systems with simultaneous wireless information and power transfer. The algorithm design is formulated as a non-

Energy-efficient communications, namely, green communication, have attracted more and more attention due to energy shortage and greenhouse effect. Therefore, motivated by this, we consider the uplink energy-efficient resource allocation in multiuser
