Managing resources in heterogeneous wireless networking environments

The always-increasing number of the subscribers of the mobile networks and the evolving demand for advanced services pose new requirements for the underlying networking infrastructure. On the other hand radio resources are scarce and already overexploited and the existing architectures lack the flexibility that would allow easy and efficient introduction of the emerging services. These problems led us to investigate the possibility for real-time Radio Resource Management in heterogeneous wireless networking environments. In this paper we present a methodology and an approach for designing a hierarchical system that is augmenting the functionality of wireless network architectures by enforcing smooth co-operation and is capable to react when resource shortcomings appear.
