In this paper, a seamless virtual emotion system is introduced toward appropriate emotion-based services in advanced IoT-enabled smart cities. The proposed system is supported by virtual emotion barrier with replaceable detection and hole-free property, which recognizes human emotion using wireless signal. Also, we formally define a problem with ILP formulation whose goal is to maximize the lowest detection accuracy with weak hole in replaceable barrier in order to construct seamless replaceable hole-free virtual emotion barrier ultimately. Then, a novel scheme is proposed to solve the problem. Moreover, we perform the proposed approach through extensive simulations with various scenarios and its performance is evaluated with detailed discussion.
