Cooperative Application Layer Joint Video Coding in the Internet of Remote Things

Recently the problem of interconnecting Internet of Things nodes when they are dispersed over wide geographical areas has been highlighted: this is the Internet of Remote Things (IoRT). It could be able to play a key role in disaster recovery scenarios (e.g., earthquakes, flash floods, terrorist attacks, etc.), where the presence of a communication infrastructure enabling video transmissions from the emergency areas is crucial. Local communications can be provided by incident area networks, while satellite communication systems can bridge the gap toward external networks. In this context, we propose a cooperative resource allocation mechanism, which exploits feedback from links conditions and knowledge of the adaptive coding, allowing a higher quality and more fair experience for all nodes of the IoRT transmitting videos. We implemented each element of the mentioned scenario over an emulation platform to prove the concept and show the obtained benefits.
