Autonomous predictive resource reservation for handoff in multimedia wireless networks

This paper presents a new method for predicting resource requirements of and resenting resources for future handoff calls in multimedia wireless networks. It allows handoff calls to (1) follow non-Poisson and/or non-stationary arrival processes, (2) have arbitrary resource demands, and (3) have arbitrarily distributed call and channel holding times in any cell. A statistical model, based on Wiener prediction theory, that uses only local information is developed. Our simulations show that it performs well under the above conditions as designed. Furthermore, for Poisson handoff call arrivals, identical per-call bandwidth demands and exponential call and channel holding times, it generates comparable performance with an existing method optimized only for these conditions
