Ambient Networks concentrates on the co-operation of heterogeneous networks over multiple domains and accesses. One of the main goals of the project is the integration of developed concepts for validation purposes. This paper presents a performance analysis on the integration of mobility triggering and Host Identity Protocol (HIP) based mobility on the Ambient Networks/FreeBSD platform. The scalability of triggering and handover latency has been focused on in terms of different mobility triggers and access technologies. The results enable identification of the largest delay components, which have been analyzed. © 2008 IEEE.
