Joint connection level, packet level and link layer resource allocation in mobile cellular networks with QoS constraints

Abstract

An approximate analytical formulation of the resource allocation problem for handling multiclass on/off services in a cellular system is presented. The novelty in this paper is that all quality of service requirements at the connection level, packet level and link layer are satisfied simultaneously, instead of being satisfied only at the connection level or only at the link layer. It also shows how the QoS in the different layers is intertwined across the layers. A complete sharing policy at the connection channels is used for the resource sharing a K-dimensional Markov chain. Numerical results illustrate that a higher gain in system utilization is achieved through the joint optimization of connection/packet levels and link layer.
