The specifications of the protocols supporting mobility - MIPv6, NEMO - centralize their key functionalities on the Home Agent, which represents a single point of failure. In the context of the French research project REMORA, we have developed a solution to make Home Agent-based mobility protocols more reliable against the Home Agent failures. This paper presents the design, the implementation and the performance evaluation of a solution for Home Agent redundancy, which is based on a set of synchronized Home Agents running a protocol for failure detection and recovery. First, the protocol has been specified and designed, based on ongoing IETF drafts. Second, a fully operational prototype has been implemented and its performances have been validated and assessed on a large-scale test bed as proof-of-concept.
