Approaching Optimal Centralized Scheduling with CSMA- based Random Access over Fading Channels
Författare
Summary, in English
Carrier Sense Multiple Access (CSMA) based distributed algorithms can attain the largest capacity region as
the centralized Max-Weight policy does. Despite their capability
of achieving throughput-optimality, these algorithms can either
incur large delay and have large complexity or only operate
over non-fading channels. In this letter, by assuming arbitrary
back-off time we first propose a fully distributed randomized
algorithm whose performance can be pushed to the performance
of the centralized Max-Weight policy not only in terms of
throughput but also in terms of delay for completely-connected
interference networks with fading channels. Then, inspired by the
proposed algorithm we introduce an implementable distributed
algorithm for practical networks with a reservation scheme. We
show that the proposed practical algorithm can still achieve the
performance of the centralized Max-Weight policy
