MADF: Mobile-Assisted Data Forwarding for Wireless Data Networks

Overview In a cellular network, if there are too many data users in a cell, data may suffer long delay, and system's Quality-of-Service (QoS) will degrade. Some traditional schemes such as Dynamic Channel-Allocation scheme (DCA) will assign more channels to hot (or overloaded) cells through a Central Control system (CC), and the throughput increase will be upper bounded by the number of new channels assigned to the cell. In Mobile-Assisted Data Forwarding (MADF), the paper adds an ad-hoc overlay to the fixed cellular infrastructure and special channels-called forwarding channels - are used to connect mobile units in a hot cell and its surrounding cold cells without going through the hot cell's base station.
