The objective of this talk is to shed some light on our efforts in addressing the challenges to Resource Management (RM) in Heterogeneous Wireless Networks (HWNs). Our understanding is that establishing a comprehensive RM framework for such networks requires the consideration of elements in two dimensions – the access level and the end-to-end level. It is also crucial to accommodate the unique characteristics of HWNs. In the talk we, will detail our efforts in three main directions. The first comprises establishing a framework overlooking the interactions of network levels (network, path, link and access) in end-to-end service delivery. We describe practical mechanisms for multi-metric routing, in addition to inter-level mapping of end-to-end QoS requirements. We also describe generalized access scheduling techniques with economic considerations. The second direction entails the introduction of novel and non-traditional RM mechanisms that exploit characteristics specific to HWNs. We show how technologies within a HWN can be enhanced through joint functionalities. The third direction shows how vertical handoffs, despite their challenges, can be used to the benefit of the service provider; and how the use of wireless multihop communication can be utilized in a structurally-hybrid environment to maintain a robust network operation.
