Data communications over context-based WMNs: Delay performance evaluation

Wireless Mesh Networks (WMNs) have already shown high-potential to deal with the huge heterogeneity of user requirements and network resources, due to the flexibility and self-organization capabilities of their infrastructure. In this scope, we provide a novel context-based multi-virtual architecture, to be applied to wireless-friendly mesh networking, and to support user requirements on demand by the deployment of several adaptable Virtual Networks (VNs) for different context-aware purposes. In this paper, we present an analytical model for the proposed multi-VN architecture. Our envisioned goal is the provisioning, allocation and distribution of the total bandwidth of mesh links onto the available context-based VNs. We aim to provide and define the limits of our multi-VN approach, in terms of the number of VNs, attached mesh clients, and virtual nodes per VN, in order to accomplish feasible delays for different communication requirements, based on a correct provisioning of the required VN bandwidth.
