Software-defined networking (SDN) simplifies the forwarding devices by introducing a centralized controller. The controller calculates routing rules for the whole network and the forwarding devices cache the routing rules. This working process leads to the new-flow attack. When malicious packets with different headers arrive at the network, they are treated as new flows. These useless flows consume...
This paper presents the design of the CASPER1 middleware architecture that enables the implementation of real-time QoE-driven service management. More in detail, we thoroughly describe the new modules, methods and functionalities that need to be integrated into the network providers' infrastructure, according to CASPER. Based on this architecture, future virtualized networks can provide a closed-loop...
Many Cyber-Physical Systems (CPS) at different scales are being developed for a variety of applications that provide valuable interactions between the cyber world and the physical systems and environments. However, the development of these systems face many challenges due to the complexity of the applications. An appropriate middleware is needed to provide infrastructural support and assist the development...
Applications integrating software with a large number of physical objects and devices in a large-scale Internet of Things (IoT) networks are on the rise. Some examples of these applications are smart grids and water networks and intelligent transportation systems. As they operate in and control a large heterogeneous environment, these applications need real-time controls, powerful and scalable data...
Many servers use technologies such as virtualization or containerization to improve server utilization. These technologies pose challenges for power monitoring since it is not possible to directly measure the power use of an abstraction such as a virtual machine. Much work has been done in modeling the power use of CPUs, virtual machines and entire servers, however, there is a scarcity of work in...
This paper presents an approach for non-intrusively instrumenting standards-based event-based middle-ware. The approach has been realized in an open-source tool called Component Port Monitor (CPM). CPM uses dynamic binary instrumentation as a means to monitor events published between software components. This allows CPM to operate in contexts without any a priori knowledge of the concrete events in...
Water is an essential resource, playing a vital role in almost all human activities. Water is also a scarce resource. Population growth, industrialization, and climate change pose significant threats, necessitating on real-time monitoring of water resources. Recent developments in wireless sensor networks have made such monitoring possible, but the networks pose numerous challenges when deployed heterogenously...
To manage large crowded events is a very challenging task nowadays. People are looking for solutions in which they can easily monitor the crowd, trace individuals, study formation and deformation patterns of the crowd. Millions of Muslims from around the world gather and perform Hajj in Makkah, Saudi Arabia in the 12th month of every lunar year. To monitor the crowd during Hajj is a great challenge...
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,...
In recent years, the European Commission has enhanced strategies to promote ICT for energy efficiency in buildings and cities. In the smart city context, energy-related information coming from different data sources--both hardware and software--must be integrated into a common, smart digital archive for the city. DIMMER is a distributed software infrastructure for district information modeling and...
A large class of emerging compute-intensive applications demand real-time or near real-time processing guarantees on streaming data. Sensor processing in particular, has stringent latency requirements for carrying out its digital processing for rapidly incoming radar data streams. The consequent demands on the cluster middleware used to run such codes include (i) efficient online observation of current...
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...
The design of the embedded software for industrial systems progressively integrates more intelligent functions to ease the integration between the factory floor hardware and operator-friendly control front ends. New software development paradigms such as service oriented architecture (SOA) make it possible by embedding small footprint web servers inside small embedded devices that are connected to...
Today smart grids are an essential tool for efficient management and monitoring of electric power. Computer technologies are used to optimize the production and distribution of electrical energy in order to balance supply and demand between producers and consumers and ensure better services. In this paper we propose an ontology-based distributed architecture for supervision and control of Smart Grids...
As new technology becomes available, systems increase in complexity, which in turn, raises the expectations of users for new applications that may presumably be more complex. This spiral process requires the usage of appropriate techniques to control complexity such as decoupled design and development paradigms, and communications middleware that facilitate the development of distributed applications...
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...
The Artificial Hormone System (AHS) is a completely decentralized operation principle for a middleware which can be used to allocate tasks in a system of heterogeneous processing elements (PEs) or cores. Tasks are scheduled according to their suitability for the heterogeneous PEs, the current PE load and task relationships. The AHS also provides properties like self-configuration, self-optimization...
Managing critical infrastructures under the growing cyber-threat is becoming a matter of international urgency. The volume and frequency of cyber-related incidents on the rise yearly, and the level of sophistication is increasing. Critical infrastructures are key service providers and heavily interconnected, meaning any damaging impact would result in devastating consequences and potential cascading...
this paper proposes the solution of information service and supervision based on WEBGIS for ecotourism in China, especially around Beijing area and Yunnan Province at this stage. The platform and the technical standards of ecotourism information service and supervision are developed. The platform is consisted of the five parts, i.e. Information Infrastructure Network (IIN), Remote Sensing System (RSS),...
With the level of cyber-attacks increasing in volume and sophistication, the need for improved counter measures is growing. The repercussions of a successful attack on a critical infrastructure would result in a paralysing impact on the economy and the general population as a whole. For that reason, the framework proposed in our previous work details the use of a system for supporting security. Our...
