Project Goals Implement & deploy of Mobile IP in CS
Network. Determining best location for home agent
and foreign agent. Study best mode of operation for mobile
node (co-located COA or FA assigned COA) to achieve smooth handoff.
Auto configuration of mobile node when network change is detected.
New Ideas Achieving smooth handoff while roaming
between different 802.11 wireless LANs operated in infrastructure point mode using mobile IP.
Algorithm to determine change of network–Guessing the network change based on three
missed beacon (registration request).–Guessing network change based on signal
strength–Based on users input
Mobile IP service for ACES and TAY
Results/Lesson Learned Experimental Mobile IP is operational in
CS Network Our Algorithm helped to achieve semi-
smooth handoff while moving between ACES and TAY wireless network (30 sec approx).
Lesson learned:–802.11 does not have good support for mobile
IP smooth handoff in infrastructure mode.–No easy heuristics to determine network
change (layer2) in 802.11 access point mode.
