Handoff management in the mobile wireless Internet
The large number ofnodes in wireless networks and the fact that mobility is an important feature of a wireless system has made it a great challenge to sustain ongoing connections during handoff events. Real-time applications (e.g., Voice-Over-IP (VoIP), Video-Ondemand, and streaming) require little …

Enabling cost aware routing with auctions in wireless ad-hoc networks
… power is a precious resource in wireless ad-hoc networks, and most routing protocols that have been proposed so far do not generate cost efficient routes. In this thesis, a novel auction-based cost-aware routing scheme, called CARA, is presented. CARA is designed as an extension of the MAC layer, …
