A Greedy Link Scheduler for Wireless Networks With Fading Channels

Download Now Free registration required

Executive Summary

The authors consider the problem of link scheduling for wireless networks with fading channels, where the link rates are varying with time. Due to the high computational complexity of the throughput optimal scheduler, they provide a low complexity greedy link scheduler GFS, with provable performance guarantees. They show that the performance of their greedy scheduler can be analyzed using the Local Pooling Factor (LPF) of a network graph, which has been previously used to characterize the stability of the Greedy Maximal Scheduling (GMS) policy for networks with static channels. They conjecture that the performance of GFS is a lower bound on the performance of GMS for wireless networks with fading channels.
