Dynamic resource allocation strategy for frequency-based passive optical networks
Résumé
Dynamic resource allocation presents a key issue in passsive optical networks (PONs) for efficient and fair utilization of system resources. This paper investigates the problem of power and bandwidth allocation for the maximization of the worst weighted capacity/rate in frequency-based PONs. By deriving a convex optimization problem, we propose an optimization algorithm which gives an upper bound of the weighted capacity. In addition, an allocation strategy in terms of discrete optimization is presented to improve user weighted transmission rate.
