Executive Summary

In this paper, the authors study the distributed spectrum allocation for autonomous users transmitting delay-sensitive information over a wireless multi-carrier network. Because there is no central moderator in the network, they propose a distributed information exchange protocol for users to exchange information, which considers their heterogeneous traffic and priorities. Based on this information exchange, they propose different prediction models that enable users to dynamically select the optimal channels for transmission. They consider two types of users - myopic and foresighted users.
