Throughput Equalization for CSMA-based Wireless Networks using Mean-Field Hard-Core Model

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we consider the problem of throughput equalization for wireless devices in CSMA-based wireless networks. We model such networks using a mean-field hard-core model which ignores geometric structures of the network. Interference in a network is represented by a conflict graph, and an edge in the graph represents the hard-core constraint, meaning that the two nodes connected by the edge interfere with each other so that they cannot be simultaneously active. Degrees of nodes vary in a conflict graph, which causes unfairness since nodes with larger degrees suffer from more interference, and have less possibility of being active. Since one can evaluate mean activities of random networks with a prescribed degree distribution via belief propagation in the large-system limit, we propose a throughput equalization strategy on the basis of it. We also extend this strategy to the case of networks of clusters of devices. For the two types of networks, we provide results of Monte-Carlo simulations to verify the effectiveness of the proposed strategies.
