In the backbone network, it is desirable to find the shortest path from the source to the destination. How do you do this in a wireless network environment, where the subscribers have finite mobility? Explain clearly.

What will be an ideal response?


In a wireless network, HA (home agent) and FA (foreign agent) can be used to
deal with the mobility. If the subscribers have finite mobility, the HA and FA are
able to cooperate with each other to locate the subscriber. When a source want to
send a message to a destination and the HA has the current location information
of the destination, then the message can be delivered to a destination subscriber
along the shortest path as in the backbone network.
