Abstract
In this work we introduce a novel approach, NFC+ , to share media content on mobile device. It leverages NFC (Near Field Communication) low friction setup property to quickly exchange network settings then programmatically setups wireless technologies such as Wi-Fi, Bluetooth, and NFC to establish a secure connection and media transfer. To ensure a representative analysis, we conducted controlled
experiments for comparing the performance of NFC+ and other 8 commonly used media sharing methods for both picture and video along 2 key metrics, network setup time and the actual transmission time. The evaluation includes 4 categories: 1. Remote Storage (e.g. Facebook, Flickr), 2. Store & Forward (e.g. email, MMS), 3. Direct Transfer (e.g. Bluetooth, Wi-Fi, Hotspot), and 4. NFC+ Direct Transfer. In particular NFC+Hotspot, NFC is used for bootstrap and secure Wi-Fi Hotspot for transmission, outperforms others in both configuration and transmission phases. It shows an
improvement ranging from 1.2x – 2.1x for 1.0MB photo and 0.9x – 5.7x for 1 minute HD video compared to other methods in the categories 3. In terms of transfer time, it
shows an improvement of 23.9x – 254.5x for photo and 16.8x – 88.1x for video compared to methods in categories 1 and 2.
