FSDA: Framework for Secure Data Aggregation in Wireless Sensor Network for Enhancing Key Management

An effective key management plays a crucial role in imposing a resilient security technique in Wireless Sensor Network (WSN). After reviewing the existing approaches of key management, it is confirmed that existing approachs does not offer good coverage on all potential security breaches in WSN. With WSN being essential part of Internet-of-Things (IoT), the existing approaches of key management can definitely not address such security breaches. Therefore, this paper introduces a Framework for Secure Data Aggregation (FSDA) that hybridizes the public key encryption mechanism in order to obtain a novel key management system. The proposed system does not target any specific attacks but is widely applicable for both internal and external attacks in WSN owing to its design principle. The study outcome exhibits that proposed FSDA offers highly reduced computational burden, minimal delay, less energy consumption, and higher data transmission perforance in contrast to frequency used encryption schemes in WSN

Economic Feasibility of Wireless Sensor Network-Based Service Provision in a Duopoly Setting with a Monopolist Operator

[EN] We analyze the feasibility of providing Wireless Sensor Network-data-based services in an Internet of Things scenario from an economical point of view. The scenario has two competing service providers with their own private sensor networks, a network operator and final users. The scenario is analyzed as two games using game theory. In the first game, sensors decide to subscribe or not to the network operator to upload the collected sensing-data, based on a utility function related to the mean service time and the price charged by the operator. In the second game, users decide to subscribe or not to the sensor-data-based service of the service providers based on a Logit discrete choice model related to the quality of the data collected and the subscription price. The sinks and users subscription stages are analyzed using population games and discrete choice models, while network operator and service providers pricing stages are analyzed using optimization and Nash equilibrium concepts respectively. The model is shown feasible from an economic point of view for all the actors if there are enough interested final users and opens the possibility of developing more efficient models with different types of services.This work was supported by the Spanish Ministry of Economy and Competitiveness through projects TIN2013-47272-C2-1-R and (co-supported by the European Social Fund) BES-2014-068998.Sanchis-Cano, Á.; Romero-Chavarro, JC.; Sacoto-Cabrera, E.; Guijarro, L.

The benefits of Industry 4.0 for companies' management

The incorporation of new technologies on manufacturing was called Industry 4.0. These technologies direct the industry to a new production paradigm where there are fewer human interferences and the system is intelligent and interconnected. This connection between the system components generates the interaction of technologies with various areas of knowledge, such as digital and physical. Industry 4.0 focuses on: the intelligent production of products, methods and processes. Technologies such as RFID, sensors, processing in the cloud, are part of the many components that can be found in a system oriented by Industry 4.0. The application of these technologies has the opportunity to transform how the Operations Management is carried out in companies. This article aims to verify the contribution of the application cases of Industry 4.0 in Operations Management. From a survey of 38 success cases resulting from technological implementations related to manufacturing 4.0, it will be identified the benefits of these applications for Operations Management. The results indicate that Industry 4.0's contributions are more concentrated in the areas like Technology Management and Justin-Time Manufacturing. In addition, the maturity level of the analyzed cases is still incipient indicating a potential of increased productivity after the application of these technologies in the productive sector
