Building a Content Delivery Network among Tens of Nearby Devices Using MultihopWireless Communication

As mobile device technology advances, content delivery among nearby devices becomes increasingly important at such places as where people gather face-to-face for seminars or meetings. Conventional ways such as cloud-based services, ad hoc contents dissemination methods and file sharing peripheral devices are not enough to support this style of content delivery. In this paper, we propose a two-layered content delivery using multihop wireless communication built on an ad hoc network. This network supports content delivery among tens of nearby devices even though the underlying ad hoc network has limitation of the number of devices. We also show experiment results to reveal how the contents delivery proceeds in the network and how the network topology affects the delivery time. Important findings in the experiments are that 1MB data can be delivered to 16 devices in approximately 5.25 seconds using Wi-Fi based ad hoc connection on iOS devices, and that reducing the number of devices simultaneously sending the data leads to the less required time for delivery.
