Abstract
Mobile data traffic is important for the remote device control in Internet of Things (IoT). Due to heterogeneous usage and subscribed data caps, mobile traffic sharing is attractive for the users. This paper mainly studies how the users share the leftover traffic efficiently. In particular, it presents a framework that allows the users to share their traffic based on WiFi. The framework can collect all the users’ bids, and then the sellers allocate their traffic according to the buyers’ bids. In such scenario, the competition between the buyers exists, so how to bid efficiently is critical for the buyers. This paper models the problem as the non-cooperative game. According to the number of sellers, it considers two different cases. The existence of the Nash Equilibrium in both cases is mathematically proved.
