MADF: Mobile-assisted data forwarding for wireless data networks

Xiaoxin Wu, Shueng-Han Gary Chan, Biswanath Mukherjee, Bharat Bhargava
2004 Journal of Communications and Networks  
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.  ...  We find that, in a system using MADF, under a certain delay requirement, the throughput in a certain cell or for the whole network can be greatly improved.  ...  Compared to the network with one-hop MADF, networks with multi-hop MADF have larger average delay.  ...
