Ontologies are useful tool for data integration across heterogeneous data sets and the importance of ontologies is already widespread, yet ontology building is comparatively a less absorbed concept. Ontology specifies a set of vocabulary for a particular problem domain emphasizing on the meaning of terms. The motive of employing ontologies in semantic web(More)
The work proposes a routing algorithm that detects congestion and hence DDoS attack using age, energy and reliability as parameters. Although researchers have proposed number of mechanisms for preventing congestion and attacks in WSN but very few of them have thought of deploying ants as intelligent entities. Moreover, the previous works had been focusing(More)
Security and Privacy are two important parameters that need to be considered when dealing with Wireless Sensor Networks as WSN operate in an unattended environment and carry sensitive information critical to the application. However, applying security techniques that consume minimum resources is still a challenge and this paper makes an attempt to address(More)
— Semantic web, also known as next generation web, aims to provide context based information and services to the user. Although, ontologies play key role in implementation and exploitation of semantic web, however these fail to handle imprecision and uncertainty involved in user requests. Fuzzy logic provides a means to overcome the mentioned shortcoming(More)
This paper presents the detailed comparison of various evolutionary algorithms developed for query optimization on web servers. It is very much a known fact now that information on the web has been growing exponentially and the need of efficient extraction of information was felt long back. Therefore, researchers have been putting their time and efforts for(More)
— Our previous works have proposed the deployment of mobile agents to assist vertical handover decisions in 4G. Adding a mobile agent in the 4G could lead to many advantages such as reduced consumption of network bandwidth, delay in network latency and reduction in the time taken to complete a particular task. However, this deployment demands that the(More)
