  1. Mobile IP service for ACES and TAY • 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 • 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. • 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.
