Hi Zach, The issue with NEMO is that if nodes move from one router to another (meaning the routers doing the nemo signaling), their address change. NEMO is made to handle mobility of the whole network behind the router, not individual nodes moving from this network to another.
What you are probably looking for is Proxy Mobile IPv6 (http://www.ietf.org/rfc/rfc5213.txt) and in general the work behing done by the netlmm working group (http://www.ietf.org/html.charters/netlmm-charter.html) and the netext working group (http://www.ietf.org/html.charters/netext-charter.html).

I have been studying different ways of dealing with mobility of 6LoWPAN nodes and networks. Extended LoWPANs provide some mobility support for micro-mobility, which is good. Properly designed applications can also deal with IP addresses changing. But what if you would want to have a stable IP address for a 6LoWPAN node or a stable prefix for a whole LoWPAN? MIPv6 have several problems to be used directly by LoWPAN nodes, e.g.: - IP-in-IP encapsulation with the home agent - Security for binding management messages - Potentially large amounts of binding messages Is anyone aware of work on MIPv6 proxy mechanisms which would allow e.g. an Edge Router to proxy MIPv6 operations on behalf of a LoWPAN node? Maybe revive the Foreign Agent for IPv6? ;-) NEMO is much more clearly applicable to 6LoWPAN network mobility. The basic NEMO protocol is a perfect match, allowing an Edge Router or other router in the visited network to act as a Mobile Router and perform MIPv6 on behalf of the network. Thus maintaining constant prefixes for all LoWPANs under the router. I don't see route optimization to be necessary for NEMO used with 6LoWPAN, the performance of traffic going through the home agent should be fine.
