On random access scheduling for multimedia traffic in multi hop wireless networks with fading channels
1. On Random Access Scheduling for Multimedia Traffic in Multi-hop Wireless Networks with
Fading Channels
we develop distributed random access scheduling schemes that exploit the time-varying nature
of fading channels for multimedia traffic in multi-hop wireless networks. It should be noted that
while centralized scheduling solutions can achieve optimal throughput under this setting, they
incur high computational complexity and require centralized coordination requiring global
channel information. The proposed solution not only achieves provable performance
guarantees under a wide range of interference models, but also can be implemented in a
distributed fashion using local information. To the best of our knowledge, this is the first
distributed scheduling mechanism for fading channels that achieves provable performance
guarantees. We show through simulations that the proposed schemes achieve better empirical
performance than other known distributed scheduling schemes.
