The advent multimedia real time application demands large volume of data to execute the required quality of service (QoS). Existing centralized approach lacks support its suitability in terms of dynamic mobility, scalability, reliability, seamless connectivity, etc. This motivates host based dynamic and distributed mobility management (DMM) solution for MIPv6 protocol to execute an intelligent mobility operation at an access network level rather centralized. The presented fully DMM architecture (FDMM) is implemented for integrated WLAN and WiMAX networks, where the entire mobility functions are distributed at access level in order to achieve a fast exchange of signaling information during handover operation. In addition, IEEE 802.21 media independent handover (MIH) standard is also adopted in the proposed work to execute seamless handover procedures across a heterogeneous background. The performance analysis of MIH-FDMM is compared with existing centralized mobility management (CMM) scheme in terms of handover delay, throughput, packet loss, etc. for real time traffic classes (constant and variable bit rate (CVBR)). Simulation result proves that the combined MIH-FDMM significantly minimize the handover delay, packet loss ratio and thus accomplishes seamless service for both real time and non-real time QoS efficiency.
