Incentivizing crowdsourcing for exclusion zone refinement in spectrum sharing system

In spectrum sharing system, an exclusion zone is defined to protect both primary and secondary users from interference. Reducing the size of exclusion zone is critical for efficiently utilizing the fallow spectrum. In this paper, we propose a novel crowdsourcing augmented exclusion zone refinement framework. In our framework, a barter-like exchange model using spectrum access right is employed to incentivize the secondary users (SUs) to participate in the crowdsourcing. We further design a truthful auction mechanism to select the SUs and determine their access time in a computationally efficient way. We perform simulations to validate the proposed mechanism, and compare it with two baseline schemes.
