An Efficient Feedback-Based Trust Model for Pervasive Computing
In pervasive computing environments, pervasive devices should collaborate effectively such that the vision of pervasive computing will come true. However, without trust, pervasive devices cannot collaborate effectively. Distributed Trust Systems (DTS) may support trust and thus foster collaboration in hostile pervasive computing environments. The challenge for DTS is how to aggregate the local trust values without a centralized storage and management facility. Another challenge is that such systems should have minimal overhead in terms of computation, infrastructure, storage, and message complexity, especially in real-time embedded systems and wireless networks.
