Today’s world is increasingly relying on computer networks. The increase in the use of network resources is followed by a rising volume of security problems. New threats and vulnerabilities are discovered every day and affect users and companies at critical levels, from privacy issues to financial losses. Monitoring network activity is a mandatory step for ...

Ad hoc low-power wireless networks are an exciting research direction in sensing and pervasive computing. Prior security work in this area has focused primarily on denial of communication at the routing or medium access control levels. This paper explores resource depletion attacks at the routing protocol layer, which permanently disable networks by quickly draining node’s ...

The cloud data base service is a boon to the global technology which support various internet based application. But the serious issue behind this approach is the data confidentiality which threats the user’s dealing with the sensitive data’s. In order to overcome this problem, the authors propose a novel approach of adaptive encryption of cloud ...

The new trend is to consider node mobility to consist as a major achievement to transfer data forwarding is opportunistic Mobile Ad hoc NETworks (MANETs). This is a special class of growing and disconnected MANETs where data communication exploits at irregular interval, contact opportunities among nodes. Nodes exchange data if they are at a distance ...
