Due to the increase of video-on-demand and streaming services, the amount of data traffic in both wired and wireless networks is increasing exponentially. In order to deal with the surge of data traffic, the wired network already utilizes caches in efficient ways. In recent years, there has been ongoing research in wireless networks to add caches to devices to reduce the burden of the radio resource. While many devices can support only small-sized caches and limited-sized batteries, some devices such as cars and buses may be able to include large caches and can provide contents to other devices via device-to-device (D2D) communications. In this paper, we discuss D2D offloading using caches on mobile devices by exploiting the mobility of the devices.
