In the evolution of mobile networks, edge computing is a key technology, which provides services with proximity to users and enables various services to be operated in a virtualized platform for mobile users. Particularly, services commonly used by multiple mobile users can be simultaneously operated at multiple edge nodes, which allows users to use the service of the closest node to their access point. However, to provide session continuity for a service when the user moves, a method for optimizing the service path along with the mobility management of the user is required. In this paper, we propose an enhanced control system using the locator/identifier separation protocol to provide service path optimization with mobility management. This was achieved by integrating the location information of the service and the session information between the service and the users. The operating cost and handoff latency were analyzed. The analysis results show that the proposed system can provide an optimal service path to mobile users through fewer message exchanges and less delay than existing approaches.

In the conventional centralized mobility management schemes, it can lead to single points of failure, occurrence of a bottleneck, since all data and control are concentrated on the mobility anchor which is located in home network. In the current research of distributed mobility management, it is doing research into distributed mobility management which is supported by distributed mobility anchors. Such schemes do not consider a failure of the mobility anchor. However, it could be an issue under tactical environment since it occur non-service problem due to anchor movement, maintenance, failure, etc. In this paper, we proposed new DMM scheme named T-DMM(Tactical-Distributed Mobility Management) which can support handover even if mobility anchor breaks down. From the numerical analysis, we evaluate signaling cost and handover latency.※ 본 연구는 숭실대학교 지원으로 수행되었음.
