In order to improve the management intelligent level and the level of information sharing for higher law college instructors, and improve the efficiency of management of higher law college counselors work, and promote the sharing of college counselors and educational resources and scheduling information, Higher Law College Counselors work management system is developed and designed. The system adopts...
Efficient network communications are essential to enable network-centric warfare. However, tactical edge networks present an extremely challenging and heterogeneous networking environment due to heterogeneous architectures, dynamic topologies, unwanted adversarial behavior, interference, and other wireless channel conditions. In order to support end-user applications and guarantee system performance...
Quality of service and quality of experience are of increasingly interest for successful communication network applications, particularly for decentralized networks, such as peer-to-peer (p2p) networks. They need sophisticated monitoring mechanisms to be able to adapt the system's parameters to maintain a certain level of quality of service. In the literature, several well-studied approaches, classified...
Internet-of-Things (IoT) is no longer just a research hype, but rather a reality in which ICT plays a fundamental role. Programming the behavior of Smart Environments not only enables designers to create innovative interactive experiences for intelligent spaces, but also empowers their inhabitants to tailor the intelligent facilities according to their preferences. To that end, this paper presents...
The reliability and safety of industrial machines depends on their timely maintenance. The integration of Cyber Physical Systems within the maintenance process enables both continuous machine monitoring and the application of advanced techniques for predictive and proactive machine maintenance. The building blocks for this revolution — embedded sensors, efficient preprocessing capabilities, ubiquitous...
Communication systems in today's world are no longer traditional in nature. Platforms required for Industry 4.0 that fall under Control and Monitoring systems, are datagathering units which gather data from remote devices and monitor them. Such platforms have various components which communicate with each other for data handling and monitoring. In the traditional peer-to-peer model, every module communicates...
Tactical Edge Networks provide one of the most challenging communication environments. In order to cope with node mobility, constrained resources, and link unreliability, communication solutions designed for Tactical Edge Networks typically present highly configurable interfaces to be adaptable for various networking conditions. However, the extreme dynamicity and heterogeneity of tactical scenarios...
Accommodating multiple different applications on a single sensor node or within the same wireless sensor network (WSN) offers numerous benefits including reduced deployment cost and improved utilization of the physical substrate. This paper presents a new middleware for WSNs, called Motley. Motley, enables a shared infrastructure and multi-application support for WSNs by providing services for the...
Provision of instantaneous, mobile and dependable communications in military and safety-critical scenarios must overcome certain wireless network issues: lack of reliable existing infrastructure, immutability of mission-critical protocols and detrimental wireless dynamics with contributing factors including hidden transmitters and fading channels. Benchmarked approaches do not fully meet these challenges,...
With the development of the Internet of things, more and more sensors appear in our lives. However, at present these sensors are mostly working in isolation. If sensors that have similar or overlapped function can be linked to work together, we can greatly increase the scope and accuracy of perception. This article mainly focuses on the research and implementation of collaborative linkage mechanism...
The emergence of dynamic applications (whose data flows and their associated Quality of Service (QoS) requirements vary over time) poses new challenges to the underlying communication system and in particular to the communication network. The DDS (Data Distribution Service) middleware allows applications to dynamically and finely express their QoS needs. However, they do not map these changing requirements...
To realize the Internet of Things (IoT) vision, tools are needed to ease the development and deployment of practical applications. Several standard bodies, companies, and ad-hoc consortia are proposing their own solution for inter-device communication. In this context, DYnamic, Adaptive MAnagement of Networks and Devices (DYAMAND) was presented in a previous publication to solve the interoperability...
Unmanned Aerial Vehicles (UAV) have several uses in civilians and military applications, such as search and rescue missions, cartography and terrain exploration, industrial plant control, surveillance, public security, firefight, and others. Swarms of UAVs may further increase the effectiveness of these tasks, since they enable larger coverage, more accurate or redundant sensed data, fault tolerance,...
In order to properly support patient treatment, e-health systems need to dynamically integrate heterogeneous types of medical sensors and provide access to streams of sensed medical data independent of the patients location or the movement of the respective medical devices. Treatment processes usually include several steps and medical departments, which means that sensors have to be moved between...
Provision of instantaneous, mobile and dependable media communications in military and disaster scenarios must overcome certain wireless network issues: lack of reliable existing infrastructure, immutability of safety-certified protocols and layer-2 dynamics with contributing factors including hidden transmitters and fading channels. This extended abstract investigates a cross-layer methodology to...
Existing sensors and actuators, that can be used in an AAL (ambient assisting living) environment, work on heterogeneous network protocols, e.g., WiFi, Bluetooth, EIB/KNX and Zigbee. For a given sensor/actuator, the choice of its underlying communication protocol is optimized according to its bandwidth and/or energy needs. However, integrating sensors/actuators of heterogeneous network protocols into...
In recent years, radio frequency identification (RFID) systems have been increasingly used in critical domains such as medical field or real-time processing domains. Although important efforts have been made to make this technology more reliable and fault-tolerant, more research is needed to meet the increasing dependability requirements. In this article, we propose a dependability approach consisting...
Over last 10 years, there is constant demand on improvement of identification technology and executing/orchestrating business processes or activities at the edge rather than at Data Center. This has been possible because of convergence of the technology like Radio Frequency Identification (RFID) with sensor data under ubiquitous environment. This convergence is emerging very fast and today lots of...
The paper describes the overall design and implementation of the geographically distributed computing and data storage centre as built by the Nordic Data Grid Facility (NDGF) with the driving goal to serve the needs of the Large Hadron Collider research at CERN. In striving to federate heterogeneous resources in different administrative domains, NDGF chose to create an infrastructure using software...
Many industrial and medical scenarios today are building on mobile devices as their end systems. These devices are typically connected to backend systems via the mobile phone network with their corresponding data services. Today's network protocols are optimized for reliable transfer of voice traffic, however, available bandwidth and latency for data traffic may vary significantly with location and...
