Atlas: Adaptive Topology- and Load-Aware Scheduling
The largest strength of contention-based MAC protocols is simultaneously the largest weakness of their scheduled counterparts: the ability to adapt to changes in network conditions. For scheduling to be competitive in mobile wireless networks, continuous adaptation must be addressed. The authors propose ATLAS, an Adaptive Topology- and Load-Aware Scheduling protocol to address this problem. In ATLAS, each node computes its persistence, the fraction of time it is permitted to transmit, in a topology and load dependent manner. A distributed auction piggybacks offers and claims onto existing network traffic to compute a lexicographic max-min channel allocation.
