Tunnel-Free Distributed Mobility Management (DMM) Support Protocol for Future Mobile Networks

Abstract

The number of wireless services and devices have remarkably increased, especially since the introduction of smart phones. The population of mobile nodes (MNs) is now exceeding the traditional non-mobile nodes. Mobility is a key factor in mobile core networks as it is responsible for providing continuous communication when a MN is on the move. Currently, a centralized mobile core network architecture is implemented, which has certain limitations. Distributed mobility management (DMM) is often seen as a solution to the problems associated with centralized mobility management (CMM). Address and tunneling management are big challenges for current DMM-based mobility protocols. Keeping in mind the current advancement of mobile network architecture, this paper proposes a novel tunnel-free distributed mobility management support protocol intended for such an evolution. In addition, the performance of the existing DMM IPv6 mobility management protocols in the context of handover latency, handover blocking probability, and data packet loss is analyzed and compared to the proposed framework. The performance analyses show that the proposed tunnel-free method can reduce about 12% of handover latency, 71% of handover blocking probability, and 82% of data packet loss.

A study of routing-based distributed mobility management in supporting seamless data transmission in smart cities

“…vii) Security: the centralized anchors can be the focal point for attacks. With the routing-based DMM approach, aside from the use of standard IP security (IPSec) [25], [26], mutual authentication and authorization processes are required between the MNs, and the serving ARs are required to prevent potential attacks. viii) Wasted resources: tunneling methods in CMM and in both client-based and network-based DMM approaches require network resources (e.g., tunnel maintenance, increased packet sizes for encapsulation, increased processing time for tunnel setup, increased processing time for encapsulation and decapsulation processes).…”

Mobility Management Issues and Solutions in 5G-and-Beyond Networks: A Comprehensive Review

“…The unique method enables the DMM requirements to distribute the anchor point and efficiently guide the best packet transmission route in the mobile computing structure. Likewise, a tunnel-free DMM support protocol framework was analyzed and the performance in terms of packet loss, latency in HO, and HO blocking probability by IPv6 protocols was compared [124]. The derived framework successfully reduced HO latency by about 12%, HO blocking probability by 71%, and data packet loss by 82%.…”
