A Mechanism For Qos Path Selection In A Wlan-Umts Scenario: Mobile Agent Approach

Wireless/wireline systems have entered a phase characterized by the integration of the existing platforms into heterogeneous multi-access network architectures. The differentiated requirements of applications over this multitude of access networks need a mechanism for resource negotiation and management. The aim of the paper is to present the possibility of an inter-domain end-to-end path selection based on a set of aggregate network parameters, imposed by the source application and managed by mobile agents. The parameter set could include one-way delay, jitter and throughput. The paper presents the best path selection to the destination in a hybrid access WLAN-UMTS scenario, based on mobile agent's one-way delay estimation.
