The complementary characteristics of the existing active wireless networks provide the potential to meet the ever increasing demands of the interactive multimedia services through internetworking. Efficient Mobility Management protocols implemented in the interworking network, allows the mobile users to be continuously connected to the best available access network depending on their requirements. With the existing MIPV6, PMIPV6, and HMIPV6, etc., protocols having their own disadvantages of triangular routing, convergence latency, signalling overhead, scalability and reliability, a proficient solution is required to increase the efficiency of mobile users working with broadband services. In this paper, an EH-MIP (Enhanced Hybrid-Mobile IP) mobility management protocol for Ultra Mobile Broadband (UMB), World Wide Interoperability for Microwave Access (WIMAX) and Wireless Local Area Network (WLAN) interworking network is proposed. The EHMIP is obtained through modifying the functional elements of existing PMIV6, such as to reduce the delays involved in repeated binding catch messages in signaling. The interworking UMBWiMAX- WLAN-EHMIP architecture is implemented with a service based mobility management algorithm, to allow users to select the suitable channel by analyzing the service type and mobility conditions of the user. The QoS parameters in terms traffic sent- received, response times, for Email and HTTP, and packet end-to-end delay, packet delay variation for VoIP and Video applications are simulated and its performances are compared using OPNET.

Heterogeneous networks, service type, mobility, interworking, hybrid coupling, Mobility management, Quality of Service

In this paper, a Novel Enhanced Hybrid- Mobile Internet Protocol (EH-MIP) is proposed for the UMB- WiMAX WLAN interworking architecture. The EH-MIP network is implemented with a service Based mobility management algorithm to increase the capacity and QoS of the interworking network. The EH- MIP, obtained as a modification of the existing PMIPV6, can reduce the signaling overhead and latency, by reducing the messages transferred for handoff and route optimization. The service based mobility management still reduced the latency and increased the QoS of the network, by allocating users based on type of service and the speed of user.
