Abstract:
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.
