<span>Distributed denial of service (DDoS) attacks have been identified as one the greatest threats to software-defined networking (SDN) because they are highly effective, hard detect, and easy use, take advantage vulnerabilities in which new architecture still exists. This paper describes technique for denying RYU controller's services, can cause resources be depleted if a significant nu...

The current limitation in the synthesis of distributed H2 controllers for linear interconnected systems is scalability due to non-convex or unstructured conditions. In this paper we develop convex and structured conditions existence a controller discrete-time with an interconnection structure that corresponds arbitrary graph. Neutral interconnections storage function block-diagonal are utilized...

Switched systems are a convenient formalism for modeling physical processes interacting with a digital controller. Unfortunately, the formalism does not capture the distributed nature encountered e.g. in cyber-physical systems, which are organized as networks of elements interacting with local controllers. Most current methods for control synthesis can only produce a centralized controller, whi...

A nonlinear chattering-free sliding mode control method is designed to stabilize fractional chaotic systems with model uncertainties and external disturbances. The main feature of this controller is rapid convergence to equilibrium point, minimize chattering and resistance against uncertainties. The frequency distributed model is used to prove the stability of the controlled system based on dir...

This paper presents a method for coordinating the motion of multiple manipulators that share a common workspace. The approach employs independent motion controllers for each manipulator coupled by way of common connguration space constraints | each robot is represented as a constraint in the other conngura-tion spaces. The harmonic function-based controller for each robot guarantees collision-f...

While the notion of a Distributed DBMS has been familiar to the IT industry for several decades, within telecom networks the subscriber data management based on DDBMS technology is a novel addition to a service provider's infrastructure. Service providers are used to telecom networks that are efficient, reliable and easy to maintain and operate, in part thanks to the node model used in designin...

This paper proposes a monitoring and interpretation framework inspired in the Model–View–Controller (MVC) paradigm. Indeed, the paper proposes the extension of the traditional MVC paradigm to make it more flexible in incorporating the functionalities of a monitoring and interpretation system. The proposed model is defined as a hybrid distributed system where remote nodes perform lower level pro...

In this paper we present a novel approach in the study of the predictability of real-time message transmission and its relationship with the design of network adapters for real-time distributed systems. The aim is to limit the occurrence of large priority inversions among messages, so as to achieve a better degree of predictability. We show that when the proper network adapters are used in conj...
