Mobility Management in the HIP-based M2M Overlay Network

The HIP-Based M2M Overlay Network (HBMON) is a virtual, self-organized and secure M2M network built on the top of Internet composed of scattered mobile devices. A fundamental requirements of this overlay network is to ensure session survivability upon end-host movement. The Host Identity Protocol (HIP) provides a regular mobility support in our M2M Overlay network. However, this regular mobility strategy is not adapted for the M2M context, where the number of the devices may outnumber by several order of magnitude the number of human users. Therefore, we propose in this paper a lightweight solution to manage the mobility of M2M devices within our overlay. We analytically evaluate the signaling cost of our solution and compare it with the regular one. Then, we implement both strategies on the OMNeT++ network simulator. Finally, we evaluate the application recovery time of an M2M device experiencing a mobility episode.
