A Novel Location Management Scheme based on DNS in Proxy Mobile IPv6

Proxy Mobile IPv6 (PMIPv6) is designed to provide a network-based localized mobility management protocol, but it does not handle the global mobility of hosts. In this paper, we propose a location management scheme based on Domain Name System (DNS) for PMIPv6 which can support global mobility by using DNS as a location manager. In addition, to support large numbers of mobile terminals and enhance network scalability a paging extension scheme is introduced to PMIPv6. To evaluate the proposed location management scheme, we establish an analytical model, formulate the location update cost and the paging cost, and analyze the influence of the different factors on the total signaling cost. The performance results show that our proposed scheme outperforms the basic PMIPv6 under various parameters in terms of reducing the signaling overhead and the proposed scheme reduces signaling overhead compared to the basic PMIPv6.

A Decision-Based Hybrid Proxy Mobile IPv6 Scheme for Better Resources Utilization

Seamless mobility is always one of the major requirements of modern-day communication.In a heterogeneous and massive IoT environment,efficient network-based mobility protocol such as proxy mobile IPv6(PMIPv6),is potentially a good candidate for efficient mobility as well as resource utilization efficiency.Several extensions are devised for performance in the research domain.However,a multi-criterion decision-based resourceefficient PMIPv6 extension is required to achieve efficiency when network resources are overloaded.In this research,a multi-criterion decision-based PMIPv6 scheme is devised that provides better performance when the Local Mobility Anchor(LMA)or Mobile Access Gateway(MAG)is overloaded.The objective is achieved by monitoring the load status of MAG or LMA and based on their status,the proposed scheme adapts itself to provide seamless mobility in addition to optimal efficiency.The proposed scheme is compared with the existing LMA and MAG-based mobility management protocol extensions.Based on the analysis of the comparison,the obtained results prove that providing a decision-based PMIPv6 scheme is better for service continuity as well as optimal performance in the context of required buffering,handover efficiency,and necessary signaling cost.

5G Smart Mobility Management Based Fuzzy Logic Controller Unit

In the paper,we propose a fuzzy logic controller system to be implemented for smart mobility management in the 5G wireless communication network.Mobility management is considered as a main issue for all-IP mobile networks future generation.As a network-based mobility management protocol,Internet Engineering Task Force developed the Proxy Mobile IPv6(PMIPv6)in order to support the mobility of IP devices,and many other results were presented to reduce latency handover and the amount of PMIPv6 signaling,but it is not enough for the application needs in realtime.The present paper describes an approach based on the IEEE 802.21 Media Independent Handover(MIH)standard and PMIPv6,so we present a new vertical handover algorithm for anticipating handover process efficiently.Our object is to propose a smart mobility management that contribute in 5G wireless communication system network operating functions.Two proposed dynamic thresholds were successfully made to guaranty process triggering,and a new primitive MIH is proposed for signaling a needed handover to be done.Simulation results demonstrate a significant reduction of the handover delay,packet loss,handover blocking probability and signaling overhead.Simulation results and tests are accomplished.
