Abstract:
Multi-radio Multi-channel (MRMC) Wireless Mesh Networks (WMNs) in recent years have become a preferred choice for end users as they are reliable and extend the network connectivity on the last mile. MRMC-WMNs have already
been deployed at various places but still WMN faces link interference issues i.e Information Asymmetry (IA), Near Hidden (NH) and Far Hidden (FH) terminals. These interference issues have made the capacity of MRMC-WMNs limited. To maximize the MRMCWMN capacity in this paper we are presenting an algebraic channel assignment model that minimizes information asymmetry (IA) interference. Our proposed model optimally assigns IEEE 802.11b/g non-overlapping channels (1,6 and 11) to various links of MRMC-WMN. For extensive simulations we consider various MRMC-WMN topologies. We compare the
results of both the scenarios where our algebraic optimization model has been applied with those where the model has not been applied. Simulation results show that our proposed optimization model maximizes the capacity of MRMC-WMN up to 8%.
