— We address the problem of radio resource allocation in the Downlink (DL) of relay–aided cellular system, based on OFDMA transmission technology. There has been little work on...
— Dual-failure scenarios are a real possibility in today’s optical networks and it is becoming more and more important for carriers and network operators to consider them when ...
— In this paper1 we analyze the capacity of MIMOOFDM systems that utilize pilot symbols to acquire estimation of the radio channel at the receiver. An analytical framework is dev...
— Colluding malicious insider nodes with no special hardware capability can use packet encapsulation and tunnelling to create bogus short-cuts (in-band wormholes) in routing path...
– The IEEE 802.11e is the extension to enhance the wireless Medium Access Control (MAC) Quality of Service (QoS) for applications requiring real time services. The IEEE 802.11b i...
Abstract— In this paper, we investigate the problem of minimizing the average transmission power of users while guaranteeing the average delay constraints in time-varying uplink ...
Abstract—Most research on differential MIMO is based on spacetime block codes, aiming to achieve maximum transmit diversity and thus make the transmission more robust by the aid ...
