Communications in emergency and crisis situations

In emergency and crisis situations (ECS) like earthquakes, tsunamis, terrorist attacks, it is very important that communication facilities are operative to provide services both to rescue teams and civilians. In ECS it is very common that communication premises are often unable to provide services, either due to physical damages or traffic overload. In such a case there is the need for rapid reestablishment of communication services. In this paper the communication services that can be exploited for ECS mitigation are discussed. The usage scenarios of such services are studied. Following that and looking from a network perspective view an ECS communication network architecture is presented. This architecture aims to provide seamless interoperability of varies communication technologies often present in ECS to provide an ECS communication solution. © 2014 Springer International Publishing Switzerland

A pattern-based approach for designing reliable cyber-physical systems

Cyber-Physical Systems (CPS) appear to be of paramount importance due to their increasing use on critical infrastructure. New challenges have occurred because of the nature and the complexity of such systems in supporting heterogeneous physical and cyber components simultaneously. Failures or attacks on system components decrease system reliability creating severe consequences to CPS and the attached applications. The construction of complex CPS with respect to security and dependability (SandD) properties is necessary to avoid system vulnerabilities at design level. Design patterns are solutions for reusable designs and interactions of objects. In this work we present a pattern-based language for designing CPS able to guarantee SandD properties. The first set of SandD patterns includes the Reliability Component Composition (RCC) Patterns for designing reliable CPS. RCC patterns are encoded in Drools, which is a rule-based reasoning system. To evaluate our approach, we use RCC patterns as a methodology for designing a reliable wireless sensor network attached to a physical architecture to send monitored data to a central controller through relay nodes and paths

Blockchain-based Electronic Patient Records for Regulated Circular Healthcare Jurisdictions

Circular, data-driven healthcare is increasingly being considered as an effective model to provide efficient, cost-effective and sustainable healthcare services in the future. Central to this model is the service-dominant “building-block”-type provision of care services to patients, paired with the collaboration of healthcare providers through a common infrastructure. This combination enables the forming of a decentralized, holistic care cycle. Sharing of patient medical information is pivotal towards reaching this goal; however, preserving medical record integrity and privacy, while at the same time allowing provider interoperability are often conflicting requirements. Blockchains and Smart Contracts can provide the underlying technology to support the decentralized care cycle by addressing patient privacy and medical record integrity, while simultaneously offering efficient interoperability between providers. To demonstrate how this could be achieved, a conceptual medical record access and sharing mechanism is presented which is suitable for a system operating within a regulated healthcare jurisdiction

A Rapid Emergency Deployment mobile communication node

In an Emergency and/or Crisis Situations (ECS) like earthquakes, floods, tsunamis, fires, terrorist attacks etc. the adequate operation of communication services is of extreme importance. History has shown that poor communication in such cases resulted in several casualties. In ECS fixed communication infrastructure might be unserviceable due to sustained damages. Evermore, the communication demand is highly increased in such cases resulting in poor quality of service as both civilians and authorities are trying to establish communications. In this paper, a Rapid Emergency Deployment mobile Communication (REDComm) node is presented. REDComm nodes include wireless communication technologies, to provide various telecommunication services in ECS and interoperability between them. It incorporates an 802.11a mesh cognitive radio technology that operates in the television broadcasting frequency bands to provide a backbone networking with increased range and flexibility. REDComm is constructed upon a trailer chassis able to minimize setup time, which is valuable in ECS. The presented platform is powered by a hybrid power source that combines thermal, solar and wind energy and eliminates the need for external power supply

VirtuWind: Virtual and Programmable Industrial Network Prototype Deployed in Operational Wind Park

With anticipated exponential growth of connected devices, future industrial networks require an open solutions architecture facilitated by standards and a strong ecosystem.VirtuWind aims to develop and demonstrate an SDN and NFV ecosystem, based on an open, modular and secure framework.A prototype of the framework for intra-domain and inter-domain scenarios will be showcased in real wind parks,as a representative use case of industrial networks. Validate the economic viability of the demonstrated solution is paramount for VirtuWind. This paper details this vision and explains steps forward
