Scalable real-time gateway assignment in mobile mesh networks
The perception of future wireless mesh network (WMN) deployment and usage is rapidly evolving. WMNs are now being envisaged to provide citywide "last-mile" access for numerous mobile devices running media-rich applications with stringent quality of service (QoS) requirements. Consequently, some current-day conceptions underlying application support in WMNs need to be revisited. In particular, in a large WMN, the dynamic assignment of users to Internet gateways will become a complex traffic engineering problem that will need to consider load peaks, user mobility, and handoff penalties. We propose QMesh, a framework for user-gateway assignment that runs inside the WMN, and is oblivious to underlying routing protocols. It solves the handoff management problem in a scalable distributed manner. We evaluate QMesh through an extensive simulation (mostly of VoIP), in two settings: (1) a real campus network, with user mobility traces from the public CRAWDAD dataset, and (2) a large-s...
