Mobility Management
Mobile node changes its physical location (address) at a much smaller timescale-
network, the networking infrastructure has to ensure that
(1) m’s location [e.g., its access point (AP) in wireless local area networks (WLANs) and base
stations in cellular networks] can be determined so that a route can be established between
m and n,
(2) when m moves out of the range of the current AP [henceforth, we use the two terms,
access point and base station, interchangeably], it establishes a connection with another AP,
and
(3) the connection/data packets are rerouted correctly to the new AP.
