A Blockchain For The Collision Avoidance And The Recovery of Crashed UAVs
Michele Scarlato,Cristian Perra,Mohamed Yaseen Jabarulla,Giljun Jung,Heung No Lee 대한전자공학회 2019 대한전자공학회 학술대회 Vol.2019 No.6
The Unmanned Aerial Vehicles (UAVs) are a specific type of drones that have a large use nowadays, but which is subject to strict rules country specific. The sensors that equip the UAVs permit to perform several tasks, ranging from geolocalization to identification of objects or measurement of temperature. In several specific cases the UAVs are employed for the patrol of zones difficult or dangerous to reach, or simply far from where a human being is able to rescue a crashed one in case of an accident. It must be pointed out the possibility of crashes, due to several causes. In our work we are proposing the design of a blockchain for the collision avoidance and the recovery of crashed UAVs.
A Permissioned ISPs Blockchain For The End to End Quality of Service Enhancement
Michele Scarlato,Cristian Perra,Heung No Lee 대한전자공학회 2019 대한전자공학회 학술대회 Vol.2019 No.6
In this work we designed a permissioned ISP blcokchain for the end to end(e2e) quality of service (QoS) enhancement that shall be framed in an Internet Service Provider (ISP) cooperative scenario. The designed blockchain is able to store users’ connection data, in those connections where a lack of Quality of Service is experienced. Those data will be retrieved from the Networks Management System(MMS), and in some specific cases can be retrieved from the Software Defined Networks (SDN) controllers, of the ISPs chaining scenario that we recently proposed. We designed the blockchain and we defined the smart contract by using Hyperledger Fabric.
JPEG Pleno: Providing representation interoperability for holographic applications and devices

Guaranteeing interoperability between devices and applications is the core role of standards organizations. Since its first JPEG standard in 1992, the Joint Photographic Experts Group (JPEG) has published several image coding standards that have been successful in a plethora of imaging markets. Recently, these markets have become subject to potentially disruptive innovations owing to the rise of new imaging modalities such as light fields, point clouds, and holography. These so‐called plenoptic modalities hold the promise of facilitating a more efficient and complete representation of 3D scenes when compared to classic 2D modalities. However, due to the heterogeneity of plenoptic products that will hit the market, serious interoperability concerns have arisen. In this paper, we particularly focus on the holographic modality and outline how the JPEG committee has addressed these tremendous challenges. We discuss the main use cases and provide a preliminary list of requirements. In addition, based on the discussion of real‐valued and complex data representations, we elaborate on potential coding technologies that range from approaches utilizing classical 2D coding technologies to holographic content‐aware coding solutions. Finally, we address the problem of visual quality assessment of holographic data covering both visual quality metrics and subjective assessment methodologies.
