On the Efficiency and Complexity of Distributed Spectrum Allocation [PDF]
2007 2nd International Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2007 We study the efficiency and complexity of a distributed spectrum allocation algorithm using explicit user coordination. Users self-organize into coordination groups and adjust spectrum assignments in each local group to approximate an optimal assignment.
