Dynamic Resource Matching for Socially Cooperative Caching in IoT Networking

This work investigates content sharing among smart objects (devices) via device-to-device (D2D) communications in the social Internet of Things (IoT) by exploiting distributed content coding schemes. Aiming at minimizing the overall transmission cost, the resource matching between content transmitters and content receivers is optimized by applying matching theory. Particularly, the dynamic distributed Roth and Vande Vate algorithm is employed to optimize the matching problem, achieving a lower computational complexity and a higher system stability. In addition, social characteristics among mobile users are also exploited in the optimization problem to further increase system reliability and robustness. Numerical results demonstrate the effectiveness of the proposed scheme.
