Design and Assessment of a Reputation-Based Trust Framework in Wireless Testbeds Utilizing User Experience

In this paper a novel Trust and User Experience Framework (TUEF) that enables trustworthiness between users and testbeds is proposed. The proposed framework utilizes: (1) monitoring data from testbeds and (2) user experience data, stemming from users’ capability to provide feedback regarding their Quality of Experience (QoE) and service received. The applicability of the TUEF is demonstrated in a wireless testbed environment as a proof-of-concept implementation, while the performance evaluation is based on both real and simulated experiments. The results presented in this paper demonstrate that the proposed trust mechanism succeeds in delivering accurate reputation values even in the case where a large number of malicious users may provide false feedback.
