A distributed splitting algorithm for exploiting multiuser diversity

Multiuser diversity refers to the inherent diversity present across the user population in a wireless network. However, this requires a centralized scheduler with knowledge of each user's channel gain. Such an approach may not scale well for large network, and the delays involved in gathering the required knowledge may also limit the performance. This paper focuses on decentralized approaches for exploiting multiuser diversity, where each user only has knowledge of its own fading level, but no knowledge of the fading levels of the other users in the cell.
