En la actualidad la tecnología gana un espacio cada vez más amplio en nuestra sociedad la cual se adapta al ritmo en que esta es mejorada en todos los ámbitos el desarrollo de dispositivos de hardware al igual que otras tecnologías habilitan a nuestra sociedad para encontrar formas diferentes de comunicarnos cada vez más novedosas y generan a la vez nuevos riesgos en cuanto a sus posibles aplicaciones en la industria.En este documento se revisan brevemente propuestas de implementación de Blockchain en dispositivos de IoT en años recientes y se elaboran gráficos que muestran las áreas de enfoque de las diferentes propuestas y los años de publicación de estas, finalmente se sacan algunas interpretaciones de conclusiones en base a lo investigado.

Cyber-physical systems (CPS), robotics, Internet of Things, information and communication technologies have become more and more popular over the last several years. These topics open new perspectives and scenarios that can automate processes in human life. CPS are aimed at interaction support in information space for physical entities communicated in physical space in real time. At the same time the blockchain technology that becomes popular last years allows to organize immutable distributed database that store all significant information and provide access for CPS participants. The paper proposes an approach that is based on ontology-based context management, publish/subscribe semantic interoperability support, and blockchain techniques. Utilization of these techniques provide possibilities to develop CPS that supports dynamic, distributed, and stable coalition formation of the resources. The case study presented has been implemented for the scenario of heterogeneous mobile robots' collaboration for the overcoming of obstacles. There are two types of robots and an information service participating in the scenario. Evaluation shows that the proposed approach is applicable for the presented class of scenarios.

Abstract. The creation and functioning of intelligent robots coalition is impossible without the organization of an information interaction environment between them. To solve this problem, it is proposed to use the concept of cyberphysical framework, which involves the unification of physical and cyber (virtual) environments. Intelligent robots can interact with each of the environments. The paper proposes methodology of the cyber physical smart space creation for the intelligent robots' coalition formation and functioning, based on the concept of the "blackboard" with the support of smart contracts over the blockchain technology. It provides a new approach to the distribution of sensory, computational, information-control and service tasks between intelligent robots, embedded devices, fixed service equipment, cloud computing and information resources.

Abstract. In m-tourism applications, the proactive recommendations are especially actual for two major reasons: (1) the highly dynamic nature of the problem situation (the user continuously moves, the transport situation and weather conditions change); (2) limited possibilities of mobile devices for explicit information entry and checking large amounts of alternative solutions, but rich possibilities for tacit information entry via various sensors. The paper proposes an approach and research prototype based on the technologies of smart space and proactive recommendation systems. The architecture is based on the smart space technology. The system implementing the proposed approach helps the tourists to plan their attraction attending schedule based on the context information about the current situation in the region, its foreseen development, the tourist's preferences and previous behavior, using their mobile devices.Keywords: m-tourism, infomobility, proactive recommendation system, smart space. IntroductionThe ubiquitous world in which we live is characterized by a high mobility of individuals, most of them wearing devices capable of geo-localization (smartphones or GPS-equipped cars) [1]. Mobiquitous environment is a next generation of ubiquitous environment, which supports adaptation to mobility of people and applications, and changes in devices state. In other words, mobiquitous environment has a mobile and ubiquitous nature. One of well-known technology that implements mobiquitous environment concept is the smart space. The smart space is an aggregation of devices, which can share their resources (information and services) and operate in coalitions. This nature of smart space enables of appearance of cyber conflicts between different smart space devices (or participants) which can have different goals and situation understanding but common information space for trusted cyber relationships.
