The vast majority of sky survey image content is due to well understood phenomena, and only 0.001% of data is of interest for astronomers to study. Computer network intrusion detection exhibits vast amounts of normal user traffic, and a very few examples of malicious attacks. In computer vision based security surveillance of public spaces, observed […]
Data collection delay in providing real-time data acquisition for the mobile user
A great success of Wireless Sensor Networks (WSNs). Recent advances in Wireless Sensor Network technologies provide people the ability to better understand the physical world. With the data collected from the entire network, the sensor network supports a variety of applications, including security surveillance, localization, information enquiry, and transmission. The ubiquitous data collection by mobile […]
Policy management is protect sensitive information
THE method of policy based management is widely used to manage complex and large scale network systems. The traditional framework of policy based management consists of four core components: PDP (Policy Decision Point), PEP (Policy Enforcement Point), PAP (Policy Administration Point) and PR (Policy Repository). A well-trained policy administrator or group will specify, verify policies […]
Privacy Preservation in distributed social network using clustering technique
Networks are structures that describe a set of entities and the relations between them. A social network, for example, provides information on individuals in some population and the links between them, which may describe relations of friendship, collaboration, correspondence and so forth. An information network, as another example, may describe scientific publications and their citation […]
QoS- Chord4S achieves higher data availability Web based services
SERVICE-ORIENTED Computing (SOC) is emerging as a new aradigm for developing distributed applications. Service discovery, among the most fundamental elements of SOC, is critical to the success of SOC as a whole. Traditional service discovery approaches of the web services technology. Centralized service registries used by UDDI may easily suffer from problems such as performance […]
CF-based web service recommender systems and QoS space visualization
Web services are software components designed to support interoperable machine-to-machine interaction over a network. The adoption of web services as a delivery mode in business has fostered a new paradigm shift from the development of monolithic applications to the dynamic setup of business process. The number of public web services is steadily increasing. Implementing service-oriented […]
A Dynamic Load balancing distributed algorithm for a strategy in a real CDN Environment
A Content Delivery Network (CDN) represents a popular and useful solution to effectively support emerging Web applications by adopting a distributed overlay of servers. A CDN consists of an original server (called back-end server) containing new data to be diffused, together with one or more distribution servers, called surrogate servers. Periodically, the surrogate servers are […]
PAIRSE-Privacy Model for Web service Composition
A popular medium for data publishing and sharing on the Web. Modern enterprises across all spectra are moving towards a service-oriented architecture by putting their databases behind Web services, thereby providing a well-documented, platform independent and interoperable method of interacting with their data. This new type of services is known as DaaS (Data-as-a-Service) services where […]
Network Traffic Characterization Using Triangle area-based Multivariate Correlation Analysis
DENIAL-OF-SERVICE (DoS) attacks are one type of aggressive and menacing intrusive behavior to online servers. DoS attacks severely degrade the availability of a victim a host, a router, or an entire network. They impose intensive computation tasks to the victim by exploiting its system vulnerability or flooding it with huge amount of useless packets. The […]
A Online Social network in Peer-to-peer assisted Video on Demand Network
Social networks (OSNs) (e.g., Facebook, Twitter) are now among the most popular sites on the Web. An OSN provides a powerful means of establishing social connections and sharing, organizing, and finding content. OSNs are organized around users. OSN users establish friendship relations with real world friends or virtual friends, and post their profiles and content […]
