Abstract

Achieving seamless wireless access in a heterogeneous environment is the next milestone in wireless network engineering. In this poster we present steps in developing SmartA, an advanced access architecture for efficient service delivery in heterogeneous wireless networks. This architecture makes use of “cognitive” methods to achieve its function. First, we address the problem of representing QoS knowledge for translating application requirements to network requirements and identify a suitable technology to achieve this. Then, we present an evaluation of the Assignment Engine. The Assignment Engine is a component of SmartA which is responsible for optimally assigning services to radio access interfaces to be delivered. The engine uses multiobjective optimization to determine feasible assignments.
