A Study on Survivability of Mobile Network Nodes
in the Network Mobility
  • Sang Young Lee, Jin Seok Yang, Dong Soo Kim and
    Tai Myoung Chung

Introduction
  • Increase network host user, then increase
    incidents

Related works
  • NEMO(Network Mobility)
  • A Mobile Network is an entire network, moving as
    a unit, which changes its point of attachment to
    the Internet. A NEMO may be composed by one or
    more IP-subnets
  • IETF NENO WG

4
Related works
  • CITRA(cooperative intrusion traceback and
    response architecture)
  • DARPA, NAI, UC Davis

5
Related works
  • Survivability
  • The capability of a system to fulfill its mission
    in a timely manner, even in the presence of
    stresses
  • Stresses include attacks, failures, accidents,
    and abnormal loads
  • DARPA
  • Survival by defense
  • Use of redundancy
  • Monitoring
  • QoS(Quality of Service)
  • Self-check
  • Application adaptation
  • BBN Technology

6
Current Issues
  • NEMO
  • Single point failure in AR, MR
  • Low process capability, Battery and Bandwidth of
    MNNs
  • QoS Performance
  • Security
  • Confidentiality
  • Authentication
  • Authorization
  • Location Privacy
  • Access Control VMN
  • Survival by Defense - Resource Monitoring
  • Guarantee QoS

Conclusions Future Works
  • Advantages
  • No corruption of service in the AR, MR
  • Guaranteed QoS, Improved Security in the NCS
    community
  • Access control, Authorization for MNNs
  • Conclusions
  • Survival by defense-enabling in AR, MR
  • Prevent some attacks
  • QoS improvement by resource management
  • Future works
  • Need consideration of Multi-homing in NEMO
  • Minimize performance decrease of MNNs
  • Formalize a method of symptoms detection
