Abstract :
The vital trend inside wireless networks is the heterogeneity of access technology. Vertical handover management is one of key challenges in such environment to ensure seamless mobility and service continuity especially in the case of network mobility. To deal with some of these challenges, numerous efforts were made in the context of standards and scientific research to perform the vertical handover process such as the IEEE 802.21 Media Independent Handover framework and the Network Mobility Basic Support Protocol. However, these optimizations stay insufficient to solve all issues. This paper proposes new mobility management framework in the case of Network Mobility handover. The proposed scheme is based on the principal concepts of IEEE 802.21 for context information gathering and optimized handover decision making. Also, a Modified P-NEMO for the handover execution phase is suggested to overcome the dependence of standardizations on the NEMO application deployment and the infrastructure network. Detailed simulations show that our proposed framework provides less complexity and better performance for enhancing vertical handover.
