Fair Randomized Antenna Allocation in Asynchronous MIMO Multi-Hop Networks
Abstract—Previous work has shown that CSMA-based protocols such as the IEEE 802.11 can yield flow starvation in multihop wireless networks. While prior protocol designs alleviat...

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...
