Optimizing transmission rate in wireless channels using adaptive probes
Abstract— We consider a wireless system with multiple channels where each channel is either on or off, and probing the state of any channel incurs a cost. We present a polynomial...

Sensing and Probing Cardinalities for Active Cognitive Radios
—In a cognitive radio network, opportunistic spectrum access (OSA) to the underutilized spectrum involves not only sensing the spectrum occupancy but also probing the channel qua...

Optimal Competitive Algorithms for Opportunistic Spectrum Access
We consider opportunistic spectrum access (OSA) strategies for a transmitter in a multichannel wireless system, where a channel may or may not be available and the transmitter must...

An Analytical Study of a Tradeoff Between Transmission Power and FEC for TCP Optimization in Wireless Networks
- It is well known that TCP has performance problems when wireless links are involved in the end-to-end connection. This is due to the high bit error rate characterizing wireless l...
