FAST CASH: FAir and STable Channel ASsignment on Heterogeneous Wireless Mesh Network

— Nowadays wireless mesh routers are facilitating with more wireless channels than ever because of the advanced wireless communication technologies such as OFDM, SDR and CR(cognitive radio). With multi-radio and multichannel communication capability, spectrum heterogeneity are widely existing in multi-radio wireless systems, such that network performances usually suffer from channel bandwidth and transmission power discrepancy. Many seminar works having been proposed are generally focusing on throughput maximization in a given network configuration, which would suffer from highly dynamic network topology and variable spectrum conditions. In this paper, we prove that, heterogeneity in wireless network would lead to resource constrained regions, and unfair wireless resource allocation would deteriorate throughput on some links. In this paper, we propose a fair and stable scheduling algorithm on heterogeneous multichannel multi-radio wireless mesh network (MCMR WMN), balancing these tw...
