Abstract— The problem of resource allocation (RA) in a downlink OFDMA system is examined under the realistic assumption of imperfect channel state information (CSI) at the base s...
Abstract— In this paper, a performance analysis of a dualbranch switched diversity system operating on identically distributed Nakagami-m fading channels is presented. An adaptiv...
We study the security of communication between a single transmitter and multiple receivers in a broadcast channel in the presence of an eavesdropper. Characterizing the secrecy ca...
—In energy harvesting communication systems, an exogenous recharge process supplies energy for the data transmission and arriving energy can be buffered in a battery before consu...
We propose to develop wireless Sensor Networks with Mobile Sinks (MSSN), under high sensor node density, where multiple sensor nodes need to share one single communication channel...
