Operation of Mobile IP Operation of Mobile IP

  • Mobility agents (i.e., foreign agent and home

Mobility agents (i.e., foreign agent and home agent) advertise their beacons (advertisement agent) advertise their beacons (advertisement messages) messages)

  • Mobile node can detect if it is in home network or

Mobile node can detect if it is in home network or foreign network foreign network

  • If it is in a foreign network it obtains COA

If it is in a foreign network it obtains COA

  • Mobile node registers its new COA with its home

Mobile node registers its new COA with its home agent, possibly via a foreign agent agent, possibly via a foreign agent

  • Home Agent sends registration reply to the

Home Agent sends registration reply to the mobile node mobile node

  • All the packets that correspondent node wants to

All the packets that correspondent node wants to send to the mobile node, will be sent through an send to the mobile node, will be sent through an established tunnel between home agent and established tunnel between home agent and foreign agent foreign agent

  • Mobile
