Resource reservation is a key management function in future wireless networks, particularly to provide high-end multimedia applications to mobile users with Quality of Service (QoS) guarantees and to optimize the overall system resource utilization. In prediction based resource reservation, the radio resource is reserved from an a priori estimation of the future traffic load. In this paper, the authors have presented a scheme for proactive resource reservation in next generation wireless networks. In this scheme, the future traffic estimation is based on Normalized Least Mean Square (NLMS) adaptive filtering method. Based on the estimated characteristic of future traffic load, network congestion notification and network utility factor are evaluated.
