Interconnecting standard M2M platforms to delay tolerant networks

In some use cases, a persistent end-to-end connection between a given data source and a destination may never be present. Consequently, traditional routing protocols cannot be directly applied for delivering data. One example are Wireless Sensor Networks (WSN), due to the limited capabilities of the connected nodes and the lack of a reliable connection between them. Such networking paradigms are known as Delay-Tolerant Networking (DTN) as they can tolerate a relatively higher delay. The implementation of Smart Cities is based on connecting the ubiquitous existent nodes and sensors via Machine-to-Machine (M2M) platforms, however this is challenged by the unreliable or non-persistent end-to-end connections in some scenarios. This paper proposes an architecture to interconnect Standard ETSI/oneM2M M2M platforms to DTNs that apply a wake-up system for resource-constrained sensors.
