Indra Sistemas S.A. have designed and developed a safety and secure solution system for the rail transportation environment based on a distributed architecture under the domain of the Industrial IoT that enables V2V, V2I, and I2I communications, allowing peer-to-peer data sharing. UPM has designed and implemented a HW-based security infrastructure for extreme edge devices in IoT. The implementation takes advantage of HW accelerator to enhance security in low resources devices with a very low overhead in cost and memory footprint. Current security solutions are problematic due to centralized control entity. The complexity of this kind of system resides in the management, in a decentralized way, of the security at each point of the distributed architecture. This chapter describes how the system secures all the infrastructure based on a distributed architecture without affecting the throughput and the high availability of the data in order to get a top-performance, in compliance with the strengthen safety and security constrains of the rail environment's regulations.

The Relationship

In recent years space-science and exploration have become more accessible due to the popularization of the concept of CubeSats. CubeSats are being used as a result of their convenient size and weight requirements, allowing for target missions to be designed, developed, and launched with a significant reduction of costs compared to traditional space missions.  Furthermore, the development of target missions has become more intricate, forcing a shift in the traditional notion of using a centralized control architecture to a distributed architecture.  A distributed architecture tackles the problem of a possible functionality loss over the control unit. This paper describes the extension of capabilities of the Multi-Agent Systems Framework for Embedded Systems (MAES). This extension provides MAES framework with the ability to perform inter-platform communication, so now the control unit architecture can be broadened allowing agents from different platforms to interact and perform cooperatively different routines designed by the developer, so it is not limited to the capabilities of just one platform. Moreover, this paper shows the results of the experimental setup showing the precision of inter-platform message exchange and the relationship between the delay of the exchange of inter-platform messages and the number of agents that are simultaneously running on each platform.

Decisions Under Uncertainty

Peer-to-Peer (P2P) and Grid systems serve whole communities of users, and are thus good examples of information systems that should realize social goals. One of the most important social goals is fairness. For that reason, P2P and Grid systems incorporate many mechanisms, algorithms and methods for providing fairness that are referred to as Fairness Management in this chapter. Information systems that serve communities of users can also apply social concepts to support users. Trust is one such concept that is often applied in P2P and Grid systems that apply Trust Management to support users in making decisions under uncertainty that is due to other users’ behavior. This chapter describes Trust Management and Fairness Management in P2P and Grid systems, showing that the two subjects are connected. Trust Management can be used to improve fairness without centralized control. The chapter includes a demonstration of fairness emergence due to trust management.

The Impact

Mobile information technologies within organizations shape the way work is conducted. Equally, working practices and organizational arrangements shape the specific technological configurations. Whereas much of the research into mobile communication emphasizes peer-to-peer voice and message communication, the organizational use of mobile communications has for much longer engaged in more complex configurations of mobile technologies. As such, the organizational experiences precede the widespread consumer use of a diversity of smartphone and tablet apps. This chapter explores, based on a review of the related literature, the broader role of mobile communications where peer-to-peer mobile voice and message connectivity is only one aspect among several. The chapter discusses in detail and exemplifies through cases the impact of mobile communication on interactional barriers, the degree of individual discretion and centralized control, and the possibilities to exercise algorithmic agency. Portfolios of data services shape the possibility for redesigned and complex collaborative patterns.
