Multiple Channel Design (MCD) has been adopted widely in wireless networks to increase throughput and reliability with relatively less energy consumption. Due to physical restrictions of sensor nodes, applying multiple radio channels in sensor networks poses significant challenges, particularly on energy consumption. To address such challenges, we propose an energy-aware MCD scheme called SmartChannel...
The success of current trust and reputation systems is on the premise that truthful feedbacks are obtained. However, without appropriate mechanisms, silent and lying strategies usually yield higher payoffs for peers than truthful feedback strategies. Thus, to ensure trustworthiness, incentive mechanisms are critically needed for a reputation system to encourage rational peers to provide truthful feedbacks...
With emerging Internet-scale open content and resource sharing, social networks, and complex cyber-physical systems, trust issues become prominent. In this paper, we propose a trust vector based scheme (VectorTrust) for aggregation of distributed trust scores. Leveraging a Bellman-Ford based algorithm for fast trust score aggregation, VectorTrust features localized and distributed concurrent communication...
