Recently the cloud computing paradigm has been receiving significant excitement and attention in the media and blogosphere. To some, cloud computing seems to be little more than a marketing umbrella, encompassing topics such as distributed computing, grid computing, utility computing, and software-as-a-service, that have already received significant research focus and commercial implementation. In this paper, […]

RUNTIME PERFORMANCE EVALUATION OF RELATIONAL KEYWORD SEARCH TECHNIQUE
Keyword search on semi structured data (e.g., XML) and relational data differs considerably from traditional IR. A discrepancy exists between the data’s physical storage and a logical view of the information. Relational databases are normalized to eliminate redundancy, and foreign keys identify related information. Extending the keyword search paradigm to relational data has been an […]
RELATIONAL KEYWORD SEARCH TECHNIQUES BASED ON AN EMPIRICAL PERFORMANCE EVALUATION
Keyword search (KWS) over relational databases has recently received significant attention. Many solutions and many prototypes have been developed. This task requires addressing many issues, including robustness, accuracy, reliability, and privacy. An emerging issue, however, appears to be performance related: current KWS systems have unpredictable running times. In this paper, we present the most extensive […]
Reputation-Based Trust for a Cooperative Agent-Based Backup Protection Scheme
This paper explores integrating a reputation-based trust mechanism with an agent-based backup protection system to help protect against malicious or byzantine failures. A distributed cooperative trust system has the potential to add an additional layer of protection designed to operate with greater autonomy. This trust component enables the agents in the system to make assessments […]
TAG POLLUTION ATTACK DETECTION USING TAG ENCODING SCHEME TO LINEAR NETWORK CODING
Linear network coding is a technique which can be used to improve a network’s throughput, efficiency and scalability, as well as resilience to attacks and eavesdropping.
