전술 기동망의 이동성 지원을 위한 PMIP기반분산 이동성 관리 적용방안

Abstract

The tactical network has several different characteristics compared with commercial internet network such ashierarchical topology, dynamic topology changing and wireless link based connectivity. For considering IP mobilitymanagement in the tactical network, current mobility management using Mobile IP(MIP) is not suitable with somereasons such as non-optimal routing paths and single point of failure. Proxy Mobile IP(PMIP) which supportingnetwork-based mobility in hierarchical manner can provide optimal routing path in the tactical network environment,but centralized anchor is still remained a threat to the stability of the tactical network which changes its topologydynamically. In this paper, we propose PMIP-based distributed mobility management for the tactical networkenvironment. From our design, routing paths are always configured in optimized way, as well as path is recoveredquickly when the mobility anchor of user is failed. From numerical analysis, comparing to other mobility scheme,result shows that the proposed scheme can reduce packet transmission cost and latency in tactical network model.
