Due to its ad hoc, infrastructure-less self-configuring and collaborating nature, wireless sensor networks (WSNs) are very much vulnerable to different security threats. The goal-oriented nature of many sensing applications results in collaboration. In fact, collaboration helps to improve WSNs efficiency as well as the data-centric behavior of WSNs. Collaboration along with its advantages like efficient...
We apply the notion of trust to situations of document editing, to select the successive editors of the document and avoid unnecessary readings by all collaborators after each modification. Two mechanisms using trust to improve that process are proposed, and compared to the situation without trust. Simulation results suggest that trust can improve the efficiency of the collaborative work.
Trusted Layered Sensing has evolved from an Air Force Research Laboratory (AFRL) initiative to a vision now shared across government research agencies, industry, and academia. “Trust” is viewed as the most critical issue affecting Layered Sensing architectures since it's impossible to build Situational Awareness (SA) out of inaccurate, misleading, or denied information. Sensing systems (SS) consist...
Establishing trust in a distributed computing environment is one of the most challenging and important aspects of cluster computing. Achieving optimal performance in clusters forces the migration of processes to other nodes. This is where trust comes into play. A secure trusted environment is needed in order to ascertain the credibility of the participating nodes working together to achieve a goal...
