Adaptive Bandwidth Allocation Via Dynamic Programming in a Shared Wireless Network

Among all related issues in shared wireless networks, the bandwidth allocation mechanism should be one of the most important ones that affect system efficiency, QoS, and the revenue of network operators. In this paper we present a model for the bandwidth resource sharing in a wireless access network among multiple mobile virtual network operators (MVNOs). Within this model, we propose an efficient scheme to adaptively allocate the bandwidth in accordance with the traffic fluctuation. Our proposed bandwidth allocation scheme adopts the technique of dynamic programming to maximize the expected total revenue across multiple stages from the perspective of the facility provider. Meanwhile, we also allow various MVNOs to compete for bandwidth resources by setting the prices. The design is then evaluated by simulation results and proved to be efficient and beneficial.
