a method for deformation computation based on strain tensor elements, as an alternative to the usual way of application of gradient of displacement vector, is proposed. the method computes directly the strain tensor elements from the computed/observed changes in distances and angles between the stations of a geodetic network in two epochs of observations. displacement vector which is determined...

Smart communities of the future have features that make them susceptible to novel forms of cyber-attack and a potential loss of privacy for the citizens they serve. We view these communities as metro level wide area control systems with sensors and actuators located in residences, the workplace, in mobile vehicles and even worn on the body. In addition, this distributed system may not be subjec...

Abstract—Recently, attention is particularly focused on the research of Software defined network (SDN) for reducing network management complexity. The one of a key technology of SDN is OpenFlow. OpenFlow provide a centralized controller for network and the scalability of controller is main issue. In this paper, we propose a high-speed routing engine for improve the scalability of OpenFlow contr...

A flexible, efficient and secure networking architecture is required in order to process big data. However, existing network architectures are mostly unable to handle big data. As big data pushes network resources to the limits it results in network congestion, poor performance, and detrimental user experiences. This paper presents the current state-of-the-art research challenges and possible s...

Vulnerabilities and backdoors in NOS (Network operating system) allow malicious actors to disrupt network or hijack NOS. The current work proposes a NOS architecture called secure control plane (SCP) that enhances security through a rotation of hetergeneous and multiple NOSs.Theory analysis proves validity and availability of the SCP and its more effective security performance over traditional ...

Real-time systems (RTS) require dependable delay guarantees on delivery of network packets. Traditional approaches for providing such guarantees for mission critical applications require the use of expensive custom built hardware and software resources. We propose a novel framework that reduces the management and integration overheads of the traditional approaches by leveraging the capabilities...

The networking industry, compared to the compute industry, has been slow in evolving from a closed ecosystem with limited abstractions to a more open ecosystem with welldefined sophisticated high level abstractions. This has resulted in an ossified Internet architecture that inhibits innovation and is unnecessarily complex. Fortunately, there has been an exciting flux of rapid developments in n...
