Due to the important developments in the area of wireless networks and mobile computing, P2P networks-based 3D streaming over thin mobile devices is starting to gain the interest of many research works. Nevertheless, one of the main challenges that need to be resolved is the supplying partner selection issue that consists of selecting the source that holds the required 3D data. The selection process...
We propose three energy-optimal distributed schemes for the half-duplex relay channel with block fading to maintain a desired source rate. We consider both network energy consumption and consumption of the relay alone, assuming only local channel knowledge. Then, we combine both into a generalized distributed energy-efficient scheme. In these schemes, the source uses message splitting and allocates...
In Wireless Sensor Networks (WSNs), controlling transmission power is a commonly used technique to extend battery life. This paper describes a novel mechanism using measured RSS (Received Signal Strength) to calculate optimal transmission power. This technique works in multipath environments and with nodes with differing transmission capability. Our technique achieves automatic configuration employing...
Cognition in radio communication is a valuable means of improving spectrum utilization and can contribute to reducing energy consumption in wireless communication systems. This paper proposes a power control scheme using spectrum hole lifetime to diminish cognitive radio energy consumption. The secondary users' transmission power level will be adapted in different licensed channels subject to the...
