Abstract

In this paper, we present an all-IP heterogeneous wireless testbed for Radio Access Technologies (RAT) selection and end-to-end (e2e) Quality of Service (QoS) evaluation. Presented testbed includes three different Radio Access Networks (RANs): UTRAN, GERAN, and WLAN; and the Core Network (CN) based on DiffServ technology and Multiprotocol Label Switching (MPLS). As an example two RAT selection algorithms implemented in the testbed, Network- Controlled Cell-Breathing (NCCB) and fittingness factor are described and analyzed in more details. The paper provides also simple case study that validates and compares both mentioned algorithms in a basic heterogeneous environment using the presented testbed.
