Methods for node localisation in sensor networks usually rely upon the measurement of received strength, time-of-arrival, and/or angle-of-arrival of an incoming signal. In this pap...
Recent theoretical results show that it is optimal to allow interfering sources to transmit simultaneously as long as they are outside a well-defined exclusion region around a de...
The paper addresses the relay node placement problem in two-tiered wireless sensor networks. Given a set of sensor nodes in Euclidean plane, our objective is to place minimum numbe...
WiMAX has attracted a lot of attention recently in the telecommunication community including researchers, product developers and service providers. Numerous papers have been publis...
