Connectivity in Multi-radio Multi-channel Wireless Mesh Networks

Wireless mesh networks are emerging as a favorable technology for last-mile Internet access. Nodes in WMNs can be equipped with multiple radios which work in different channels to increase the available bandwidth. In this work, we present an analytical model for almost surely k-connectivity of WMNs with multi-radio multi-channel in two-dimensional case through a random uniform distribution and the analysis of the minimum node degree. Based on our model, the numerical results show the factors - the density of nodes, the minimum degree of neighbors, the probability of selection of channels and the different transmission ranges can impact the connectivity probability significantly by their variable values.
