Mobility:
Issues and Ideas
nAs mobile
devices roam, the proxy (or proxies) might have to migrate as well:
§schemes are
only efficient if proxy is on direct path between mobile and correspondent host
§however, not
every move requires a proxy migration
nWhen
to migrate: performance question
§e.g., when
are advantages of migration higher than costs?
nHow
to migrate: infrastructure question
nConsequences
of migration: mobility models, simulations
§e.g., what
happens if all cellular subscribers move into same cell (the one that covers the big shopping mall)
