We consider the problem of identifying the insider-based attacks in the form of jammers in multi-channel wireless networks, where jammers have the inside knowledge of frequency hopping patterns and any protocols used in ...

Applications like Twitter which use chat-like short messaging systems (SMS) have been widely used in public, political, military, emergency, humanitarian and other fields. Such applications usually involve servers ...

Existing literature shows that Peer-to-Peer (P2P) content sharing can result in significant scalability gains in addition to assisting content distribution networks (CDNs). However, currently proposed CDN and P2P hybrid ...

This is just a short abstract describing a simple extension of our previous work on efficient distributed file system (EDFS) for cloud computing. The extension, GreenEDFS, aims at making EDFS more energy efficient. The ...

With the fast growth of (online) content and the need for high quality content services, cloud data centers are increas- ingly becoming the preferred places to store data and re- trieve it from. With a highly variable ...

Policy engineering for access-control security has traditionally focused on specification and verification of safety properties (``nothing bad happens''). In most real systems however, resources and access mechanisms are ...

With the fast growth of (online) content and the need for high quality content services, cloud data centers are increasingly becoming the preferred places to store data and retrieve it from. With a highly variable network ...

Data center energy costs are increasing rapidly and cooling energy costs form a substantial part of the overall energy costs. Existing research on reducing cooling costs focuses on thermal-aware task placement and ...
