The Unmanaged Internet Architecture (UIA) provides zero-configuration connectivity among mobile devices through personal names. Users assign personal names through an ad hoc device introduction process requiring no central allocation. Once assigned, names bind securely to the global identities of their target devices independent of network location. Each user manages one namespace, shared among all the user's devices and always available on each device. Users can also name other users to share resources with trusted acquaintances. Devices with naming relationships automatically arrange connectivity when possible, both in ad hoc networks and using global infrastructure when available. A UIA prototype demonstrates these capabilities using optimistic replication for name resolution and group management and a routing algorithm exploiting the user's social network for connectivity.
