Current literature has identified several issues with centralized mobility management in 5G-based Intelligent Transportation Systems (ITS), where 5G-enabled vehicles are expected to exhibit varying mobility patterns. So, distributed mobility management (DMM), where control plane mobility anchors work in a distributed fashion, is of keen interest to current researchers. Although existing DMM solutions, such as distributed mobile IPv6 (DMIPv6), distributed proxy MIPv6 (DPMIPv6), distributed mobility management software defined networking (SDN-DMM), distributed routing (D-Routing), and their derivatives appear to work fine in evolving 5G-based ITS, they cannot be applied directly. Further, to gauge their adaptability to different ITS scenarios, a thorough investigation of their performances is very much needed. Our key contributions in this paper include investigating DMM issues in 5G-based ITS scenarios, porting DMM schemes in 5G ITS, and developing a Markov model to evaluate handoff performance. The results show that DMIPv6 and DPMIPv6 outperform SDN-DMM and D-Routing in terms of end-to-end delay and signaling cost, with the latter increasing delay by 6-23% and signaling cost by 135% and 78%, respectively. However, SDN-DMM and D-Routing excel in packet loss ratio (15-20% lower), throughput (20-25% higher), and packet delivery cost (40% lower). In edge cloud flow mobility, SDN-DMM and D-Routing show better packet loss ratio as packet loss is caused by servers’ sensitive application delays rather than handoffs.

Abstract
Current literature has identified several issues with centralized mobility management in 5G-based Intelligent Transportation Systems (ITS), where 5G-enabled vehicles are expected to exhibit varying mobility patterns. So, distributed mobility management (DMM), where control plane mobility anchors work in a distributed fashion, is of keen interest to current researchers. Although existing DMM solutions, such as distributed mobile IPv6 (DMIPv6), distributed proxy MIPv6 (DPMIPv6), distributed mobility management software defined networking (SDN-DMM), distributed routing (D-Routing), and their derivatives appear to work fine in evolving 5G-based ITS, they cannot be applied directly. Further, to gauge their adaptability to different ITS scenarios, a thorough investigation of their performances is very much needed. Our key contributions in this paper include investigating DMM issues in 5G-based ITS scenarios, porting DMM schemes in 5G ITS, and developing a Markov model to evaluate handoff performance. The results show that DMIPv6 and DPMIPv6 outperform SDN-DMM and D-Routing in terms of end-to-end delay and signaling cost, with the latter increasing delay by 6-23% and signaling cost by 135% and 78%, respectively. However, SDN-DMM and D-Routing excel in packet loss ratio (15-20% lower), throughput (20-25% higher), and packet delivery cost (40% lower). In edge cloud flow mobility, SDN-DMM and D-Routing show better packet loss ratio as packet loss is caused by servers’ sensitive application delays rather than handoffs.File | Dimensione | Formato | |
