Congestion Control in 4G Wireless Networks Using Coalition Game

S. V. Saboji, C. B. Akki
2012 International Journal of Computer Network and Information Security  
It aims at maximizing the utilization of the resources available and meeting QoS requirement of users as much as possible. This will reduce congestion level with vertical handoff initiation.  ...  Its main objective is to decide target networks for handoff with minimum congestion level. Our mechanism is based on the coalition game formation.  ...  Hence u({WiFi})= u({WiMAX })= u({UMTS}) =0. Any 2-players coalition reduces two thirds of the congestion and hence, u({WiFi, WiMAX })= u({WiFi, UMTS })= u({WiMAX, UMTS})=2/3.  ...
