The scope of this document is to combine the most promising IPv6 mobility mechanisms, such as Proxy Mobile IPv6 (PMIPv6) micro-mobility scheme, with an ad hoc mobility solution that can easily interconnect ad hoc heterogeneous access networks with the Internet and provide at the same time an efficient macro-mobility scheme. For this purpose, the Host Identity Protocol (HIP) has been selected.

HIP enhances the original Internet architecture by adding a new layer between the IP and the transport layers. This new layer introduces a new name space consisting of cryptographic identifiers, thereby implementing the so-called identifier/locator split. In the new architecture, the new identifiers are used for naming application level end-points, thereby taking the prior identification role of IP addresses in applications, sockets, TCP connections, and UDP send and receive system calls. IPv6 addresses are still used, but only as names for topological locations in the network.

The combination of PMIPv6 and HIP provides a macro and micro-mobility solution for a heterogeneous ad hoc mesh network deployed at the disaster site and communicating to Internet and the headquarters via satellite. The proposed combination provides an efficient mechanism for intra and inter-technology handover between Public Safety users at the disaster field and it also benefits of secure end-to-end communications inside and outside the disaster area.
