A FRAMEWORK TO RELIEVE WIRELESS HOT-SPOT CONGESTION BY MEANS OF AD HOC CONNECTIONS

摘要

In recent years, wireless public networks have been widely deployed to provide high-speed Internet access to mobile users. Due to the dynamic and uneven distribution of user requests, some access points (the so-called "hot-spots") may be congested by many users. In order to alleviate such congestion, we introduce an ad hoc relaying wireless LAN framework in this paper. A user can be served by a neighboring access point through an ad hoc connection in such a network. We propose a framework to establish such ad hoc connections. Using simulations, we show that the framework is efficient to reduce the service failure rate as well as to improve channel utilization in hot-spot networks.
