This paper presents an intelligent mobility management scheme for Mobile Wi
reless InterNet - MWIN. MWIN is a wireless service networks wherein its cor
e network consisting of Internet routers and its access network can be buil
t from any Internet-capable radio network. Two major standards are currentl
y available for MWIN, i.e., the mobile IP and wireless LAN. Mobile IP solve
s address mobility problem with the Internet protocol while wireless LAN pr
ovides a wireless Internet access in the local area. However, both schemes
solve problems independently at different layers, thereby some additional p
roblems occur, e.g., delayed handoff, packet loss, and inefficient routing.
This paper identifies these new problems and performs analyses and some re
al measurements on the handoff within MWIN. Then, a new handoff architectur
e that extends the features of both mobile IP and wireless LAN handoff mech
anism was proposed. This new architecture consists of mobile IP extensions
and a modified wireless LAN handoff algorithm. The effect of this enhanceme
nt provides a linkage between different layers for preventing packet loss a
nd reducing handoff latency. Finally, some optimization issues regarding ne
twork planning and routing are addressed.
