Abstract—In this work, we discuss how to support Video-onDemand service in multi-hop WiMax mesh networks. We are interested in the scenario that end users connect to the video se...
Pervasive computing is becoming a reality, thanks to advances in wireless networking and increased popularity of portable devices. Users of these devices will need support to deci...
In this paper, we present a Gaussian mixture model based approach to capture the spatial characteristics of any target signal in a sensor network, and further propose a temporally...
In cognitive radio (CR) networks, multi-CR cooperation typically takes place during spectrum sensing, to cope with wireless fading effects and the hidden terminal problem. The use...
—This paper considers the performance of the MAC protocols ALOHA and CSMA in wireless ad hoc networks, where the total system bandwidth may be divided into smaller subbands. In t...
