— We consider wireless multihop data networks with random multi-access mechanisms at the MAC layer. Our aim is to study the performance as perceived by users in a dynamic setting...
Utilization of Radio Frequency Identification (RFID) is often presented as improving supply chain management even though there are still few in-depth studies that support the hype...
The extent to which a wireless multi-hop network is connected is usually measured by the probability that all the nodes form a single connected component. We find this measure, c...
Abstract— In this paper, we consider the unclaimed subcarriers that no user feeds back in an opportunistic OFDMA system with a per sub-carrier power constraint. Unclaimed subcarr...
Motivated by the increasing popularity of OFDMA, this paper studies the sum-rate optimality of OFDMA as an uplink multicarrier multiple-access scheme. We address the relationship ...
