IoT Application Protocols Optimisation for Future Integrated M2M-Satellite Networks

Satellites are playing a key role in driving the vision for a truly connected world, providing ubiquitous coverage and reliability in places where no other terrestrial technology could.
While the potentials of satellites for IoT are well recognised, to allow a smooth integration of M2M and satellite networks, a lot of tweaking and optimising is still required. The M2MSAT project, funded by the European space Agency (ESA) is contributing to fill this gap, investigating optimisations for MQTT and CoAP, identified as IoT Application Protocols suitable for IoT data collection over satellite. This work outlines the efficient configuration of MQTT and CoAP in an integrated M2M-Satellite network, and presents some optimisations, designed taking into account the peculiarities of satellite links.
