Typically, topology control is perceived as a per-node transmit power control process that achieves certain networklevel objectives. We take an alternative approach of controlling ...
—In this paper we analyze the delay performance of a single user with perfect channel state information transmitting data over a wireless fading channel. We consider a dynamic re...
— We consider a wireless multiuser network where a number of source/destination pairs communicate concurrently over the same physical channel. A set of amplify-and-forward relay ...
Recently, a cooperative paradigm for single-channel cognitive radio networks has been advocated, where primary users can leverage secondary users to relay their traffic. However, i...
— In this paper, we consider a 2-hop wireless diversity relay network. We explore transmit power allocation among the source and relays to maximize the received signal to noise r...
