A study on designing ad hoc network protocol using Bluetooth low energy

In this paper, we propose a new protocol to construct ad hoc network using Bluetooth Low Energy (BLE). Especially, we are focusing on using advertising packet of BLE to construct ad hoc network, since the reach of advertising packet of BLE is longer than ordinary Bluetooth. We would like to use this kind of ad hoc network to develop support tool for disaster victims or group management tool to keep safety during school trip. We designed a protocol that allows us to construct ad hoc network efficiently using advertising packet of BLE. As our experiment using iPhones, the latency of one hop in our ad hoc network was 0.3 second and feasible to send information for our purpose.
