How do I emulate CORE node connecting to a wireless access point?

[shanv82]

I need to emulate the following: There are three network subnets, and each subnet has a wireless access point cum dhcp server. A node with a wireless interface moves across to each of these subnets, gets in proximity with the wireless access point cum dhcp server, and obtains an IP with that network. When it moves to another subnet, the node gets in proximity with the wireless access point of that network, and obtains an IP.

Straightforward way of achieving this, is for the mobile node to have three different wireless interfaces (connect the node to each WLAN/wireless connection that the subnet represents), but this is not how we do it in the real world.

1. Can this be achieved directly in CORE as of today ? 2. Is this achievable through a tweak in code ? 3. Can this not be achieved ?

Kindly advise.
