In infrastructure-less sensor networks, efficient usage of energy is very critical because of the limited energy available to the sensor nodes. Among various phenomena that consume energy, radio communication is by far the most demanding one. One of the effective ways to limit unnecessary energy loss is to control the power at which the nodes transmit signals. In this paper, we apply game theory to solve the power control problem ...
This research studies the current IEEE 802.22 system architecture and investigates the limitations in creating wireless back-haul mesh networks due to its lack of knowledge about the spectrum bands to be used. In this regard, a coordinated distributed scheme for IEEE 802.22 enabled devices to is proposed establish a mesh network with reduced interference. The coordination is initiated by the base station and is followed by the iterative joining of ...
