This paper proposes a new identifier scheme for Internet Indirection Infrastructure (i3). i3 is an overlay network on top of IP, and realizes rendezvous-based communications. It provides a general solution to deal with communication primitives such as host mobility, multicast and anycast. Although i3 provides flexible communication mechanisms, it is not optimized for mobile and wireless communications. Thus, three key problems still remain to be addressed: header overhead, multiple trigger updates and detection of a close i3 server after handover. The proposed identifier scheme, called local ID, significantly reduces the overhead without sacrificing the flexibility of i3. In a typical case, the local ID makes the total header size nearly half that of the original protocol. This paper also discusses how to adapt the local ID to various types of i3 primitives, so that a mobile host can receive all the benefits of i3 communications.
