The Software-Defined Networking (SDN) paradigm can allow network management solutions to automatically and frequently reconfigure network resources. When developing SDN-based management architectures, it is of paramount importance to design a monitoring system that can provide frequent and consistent updates to heterogeneous management applications. For the monitoring functionality to scale according...
In this paper, we present an architecture and implementation for self-managing cloud application using overlay networks and software defined networking (SDN). Through real world experiments on Amazon EC2 and Smart Applications on Virtual Infrastructure (SAVI) cloud, we demonstrate how our management mechanism autonomously maintains SLAs of application scenarios without provisioning extra resources.
In this paper, we propose a mid-range wireless power transfer system with CCL type resonant topology on source side for monitoring equipment power supply on electricity pylons. In consideration of low coupling coefficient caused by long transmission distance, a relatively high current level should be kept when using the traditional serial-serial topology(referred to as S-S topology), which increases...
With a growing number of infrastructure cloud services becoming available there are many benefits to interconnecting several cloud services. However, seamless cloud interoperability is the complex issue, especially when different cloud platforms are interconnected. One of the major aspects of federating clouds resources is network federation. Federated networks must deal not only with heterogeneous...
Software Defined Network (SDN) is a proposal to networking world for global administration and management of network services. It also provides an abstraction of networking elements. Most of the security innovations in SDN are bound to an OpenFlow security framework which creates and implement security policies while detecting malicious traffic, that too in a flexible way. Existing methodologies convert...
Demand Response (DR) refers to the scenarios in which the energy consumer reduce its own consume for some financial purpose, or even during critical energy periods. It is notorious that DR devices are indispensable in Smart Grid operations. DR allows a smart load management, and, when added to the Smart Grid operation, makes possible the optimization of Distributed Generation, Energy Storage and still...
State Grid of China plans to put a ± 500kV/3000MW four-terminal voltage source converter based high voltage direct current (VSC-HVDC) transmission system into operation by 2020. In compare to existing VSC-HVDC transmission systems, this system has higher voltage level and transmission capacity. Accordingly, grid devices and topology would be significantly different. This paper introduces configuration...
The NoC Architecture plays crucial role while designing communication systems for System on Chip (SoC). The NoC architecture is improved over conventional bus, shared bus design and cross bar interconnection architecture for on chip networks. In order to improve the Quality of Service, Congestion, Throughput and latency in NoC, Hexagonal node based architecture is proposed in our previous paper[14]...
The mobile ad-hoc networks (MANETs) represent a broad area of study and market interest. They provide a wide set of applications in multiple domains. In that context, the functional and non-functional monitoring of these networks is crucial. For that purpose, monitoring techniques have been deeply studied in wired networks using gossip-based or hierarchical-based approaches. However, when applied...
Software Defined Networking (SDN) is a new approach in network architecture which decouples the control plane from data plane. The SDN controller has the global view of the underlying network, enabling enormous research works in the area of traffic engineering (TE). Existing congestion control solutions for SDN TE are either reactive or proactive in nature. In reactive schemes when congestion event...
Network Intrusion Detection Systems (NIDS) are an integral part of modern data centres to ensure high availability and compliance with Service Level Agreements (SLAs). Currently, NIDS are deployed on high-performance, high-cost middleboxes that are responsible for monitoring a limited section of the network. The fast increasing size and aggregate throughput of modern data centre networks have come...
Software-Defined Networking (SDN) allows scalable and flexible network management without requiring expensive hardware changes. However, this technology is relatively new and creates novel security risks. In this paper, we investigate the vulnerability of link discovery service in SDN controller, which is a critical service provided by the control layer for the proper functioning of applications and...
In Data center network, with the rapid development of network applications, how to balance the network load has become the focus of everyone's attention.

In this paper, we propose a dynamic load balancing routing mechanism based on disturbance under SDN. The proposed scheme...
Wireless Sensor Network (WSN) is an integration of simple sensing, processing, storage and communication technology into cheap miniature sized devices. Distributed WSN is used for ambient intelligence, where tiny senor nodes sense, process and communicate signals to the base station (BS) for smart decision making. Nodes are deployed randomly in any unattended area for monitoring any physical attribute...
In recent past, researchers have shown a lot of interest in Under Water Sensor Networks (UWSNs) because of its application in wide range of domains. UWSN, actually a sub body of Wireless Sensor Networks (WSN), facilitate with radio communication with high-precision of information to a sink node from any of the source node. The Role of any-casting is of significant importance in the context of routing...
In the network environment with limited network resources, the overall bandwidth is usually competitively shared among various application users. The traffic engineering techniques presented for resolving the bandwidth sharing, e.g. limited traffic rate and traffic blocking, may not be able to satisfy the requirement for all types of services. In this paper, we propose an effective routing mechanism...
Opportunistic networks (OppNet) enable users to connect each other via wireless communication without connecting to the Internet. These networks have fragile structures and the topology of the network is changed frequently, so it is impossible to have a Trust Third Party as a certificate authority. There are many different attacks against these networks and one of them is Sybil Attack. In this paper,...
In nigh application, it is indispensable to discover or supervise the behavior of the surrounding situation at a fine resolution over large spatial-temporal scales therefore WSN (Wireless Sensor Network) is well-advised. Because of smaller size and low power requirement of sensor device use of WSN for watching the surrounding action is increased time to time. Numeral of sensor inside WSN is proportionate...
Distributed stream processing platforms is a new class of real-time monitoring systems that analyze and extracts knowledge from large continuous streams of data.
