Initiate
connectivity to Internet by DHCP request
|
|

Once
initial IP address has been obtained, start all

servers/demons,
etc.

Suppose
host detects movement: re-issue new
|
|
|
DHCP
request to validate current IP address
|
|
|
– |
if
okay, proceed
|
|
|
– |
if
new address needed, we have a problem
|
|
|
n |
new
IP address will not work with existing connections
|
|
|
– |
shut
down and reboot machine
|
|
|
n |
since
no other node knows new IP address, MH has to initiate
|
|
|
all
requests
|
|
|
– |
alternative:
allow DNS updates, which takes time and introduces
|
|
new
security problem
