IP Multimedia Subsystem (IMS) provide interworking networks with a common set of control and routing functions, to converge heterogeneous protocols, functional entities and applications. In this paper, a Dynamic Application Centric Resources Provisioning Algorithm (DAC-RP) for a Ultra Mobile Broadband (UMB)-Worldwide Interoperability for Microwave Access (WiMAX)–Wireless Local Area Network (WLAN)hybrid interworking network, over a novel Intelligent Internet Protocol (IIP) architecture is proposed. The proposed IIP is a unified architecture, obtained by merging IMS Call Session Control Functions (CSCFs), Application services, enhanced IMS emergency and centralized services, under a common layer. It provides the users with the access to common applications across the divergent interworking network and reduces the signalling overheads through a fused level of interaction. With the added features of the IIP, the proposed DAC-RP scheme provides a dedicated set of channels for real-time and non-real-time applications. The performance metric for the RT and NRT applications are simulated for IIP based UMB-WiMAX-WLAN hybrid interworking network developed using OPNET 14.5 and compared with the scenario using existing IMS to prove the competence of the proposed IIP.
