Abstract :
A more realistic and robust resource allocation mechanism for wireless networks is proposed which enables wireless network systems to communicate efficiently and combat harsh wireless channels. In order for a central spectrum moderator (CSM) to efficiently allocate wireless resource to wireless stations (WSTAs), overhead information is requisite. A new iterative version of the VCG (Vickrey-Clarke-Groves)-Kelly mechanism is introduced in order to reduce the amount of overhead information by appropriate selection of the initial value of bids playing an important role in convergence performance. This new mechanism uses prediction for the initial bid value for the next service interval (SI) with information of the optimal value of bids in the current SI.
