— In this paper, we investigate two selective relaying schemes in cooperative OFDM systems. Selective OFDMA relaying, where the relay selection is performed in a per-subcarrier m...
During the last few years, continuous progresses in wireless communications have opened new research fields in computer networking, aimed at extending data networks connectivity ...
Abstract— In Multiple-Input Multiple-Output (MIMO) wireless systems, since different signals are transmitted by different antennas simultaneously, interference occurs between the...
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...
—Recent progress in Wireless Sensor Networks technology has enabled many complicated real-world applications. Some of the applications demand a non-trivial amount of computation;...
