seminar 20120921

• Mobility management: user/server centric
• distribution: centralized, distribued, p2p

  Presi

• 3 layers: application – chord ring –

  • chord ring:
    • hashed data used for routing decision.
    • MA as a peer in p2p network. ←- MA as LMA (local mobility anchor) and MAG (mobile access gateway)??.
  • app layer:
    • whihch LMA will be anchor for MN
    • MAG has a LMA table (Dist. Hashing table).

  Presentation
• pros
• cons
  • fast sliding.
  • code presentation is not good, no one can read.

• integrate UPMT mobility and multi-homing.
• Anchor node as a SIP element.

• pros
  • use case explaination. better understanding.

• Handover magmt process
  • handover info gathering
  • decision: network selection
  • handover execution

* HO info

• Frequency handover: intrafrequency/ interfrequency (CDMA)
• No. of connections: hard handover (1 connection a time)/ soft handover (connected w. mult. cells).
• Administrative domains: intra admim. / inter admin.
• Necessity for handover: necessity for HO (obligatory, voluntary)/ Obligatory (
• Network type: horizontal HO (same networking tech.)/ vertical HO (diff. network tech.)

• dicision
• depends on HO info and type of HO.

1. Motivation:
   • cisco VNI Mobile: expansion of mobile data traffic.
   • hight data rates.
2. Future Telco paradigm: NGN paradigm.
   • Femtocell/ Macrocell.
3. Cognitive network management: automated, policy based, real time mgmt.
   • Control loop/
   • levels: operator, cluser, user.
4. Tools: codecom/ opnet simulator.
