Context-Aware Connectivity and Mobility in Wireless Mesh Networks (original) (raw)

Abstract

Wireless Mesh Networks (WMNs) have shown a high-potential to fulfill the requirements of the Next Generation Networks (NGNs). Although mobility management is crucial to develop large-scale WMNs, the heterogeneity of today’s Internet will imply a context-aware architecture in the future to optimize the users’ experience. Network virtualization, as a mean to share and isolate resources, can be used as an element to construct different types of virtual networks (overlays), each one optimized for a specific set of contexts: security, mobility, Quality of Service (QoS), cost, preferences. In this paper, we present a context-aware multi-overlay architecture that enables a user to connect to the WMN that best fits its requirements and approaches. We concentrate on how to build such an architecture: how a user can move maintaining its requirements through the re-configuration of overlays, and how context can be mapped, organized and distributed in the network nodes. We also discuss the entities and the complexity of this architecture.
