An OSPF based UMTS/WLAN Radio over Fiber Convergence Network for Enhanced Quality of Service

Wireless community these days debate frequently about convergence (next generation) network, a wireless system that is likely to appear after the successful deployment of the current third-generation (3G) systems. Towards convergence of various wireless networks, the integration of universal mobile telecommunication system (UMTS) and wireless local area network (WLAN) plays a major role. Enhancing quality of service (QoS) in an UMTS/WLAN convergence network is an important issue. This paper proposes radio over fiber (RoF) based UMTS/WLAN convergence network using open shortest path first (OSPF) protocol for enhanced QoS. In this paper, RoF based convergence network is analysed using routing information protocol (RIP), intermediate system-intermediate system (IS-IS) protocol and OSPF protocol, using optimised network engineering tool (OPNET). The simulation results show that the proposed OSPF based convergence network outperforms in QoS compared to existing, RIP and IS-IS based approach.
