Cross-layer Localized Mobility Management Based on SIP and HMIPv6 in Next Generation Networks

—Next Generation Networks (NGNs) are aiming to integrate different access technologies for the accessibility of heterogeneous platform under the control of IP protocol. In such a complex environment, the availability of high data rates, high bandwidth, security, and end-to-end QoS are major challenges. In this paper cross-layer localized mobility management based on Session Initiation Protocol (SIP) and Hierarchical MIPv6 (HMIPv6) is proposed to support the providence of the end-toend QoS; network and session mobility; reduce latency; and proper bandwidth management. The proposed scheme handles the mobility locally to minimize latency. Further, QoS manager is used for proper management of bandwidth. Performance analysis and numerical results demonstrate the efficiency and feasibility of proposed scheme for real time communication in terms of latency, packet loss, and traffic load.
