Variance Based Scheduling Algorithm with Relay Selectionand Resource Allocation in Cooperative OFDMANetworks
Nowadays the radio interface of several standards is enhanced
with advanced technologies such as OFDMA and extension
technology such as relay. By using those promising transmission
technology for the next generation wireless communications,
scheduling problem becomes more crucial and challenging. In
our work, we aim to maximize the overall system capacity while
selecting the most suitable relay station under fairness constraint
among both users and relay station by proposing a Gap- based
scheduling. This one considers the channel state information and
the unbalanced rate capacity of the two hops links. Simulations
results show the effectiveness of our approach in terms of
fairness and the overall system performance.
