Abstract
In a previous work, we build an M2M overlay network over the Internet in order to ensure private communication between M2M devices, M2M gateway and M2M applications. We propose in this paper to add the autonomic man- agement of this overlay network. We add the self-healing and self-optimization capabilities to the M2M gateway. The M2M gateway is able to detect failures in the overlay path and recover from them. It is also able to dynamically monitor the overlay path and select the best available path in term of RTT. These two features are provided by the reachabil- ity protocol (REAP) at the gateway level. We implement our solution on the OMNeT++ network simulator. Results highlight the novel gateway capabilities: it recovers from failures and always select the best available path.
