A Study on Construction of Ad-Hoc Network with BLE Advertisement
Kai Takahashi, Atsushi Ito · 2019
In Japan, there is a high chance of getting damage from earthquakes, tsunamis, and typhoons so we need to quickly get information about where to evacuate. Under such a situation, the deaf people are hard to get information because a lot of emergency information is delivered by sound. For them, information by vision is more suitable. We developed information delivery system with Bluetooth Low Energy. In this paper, we analyzed packet reaching rate with three nodes hopped and checked the behavior of routing function and discuss the performance of an ad-hoc network with BLE Advertisement. The performance includes the reachability of transmitted packets, the routability of the routing protocol we developed and the power consumption of BLE. The reachability is important because emergency information must reach at high rate. The routability is also important because nodes move and routes of one node to another node should quickly updated. The low power consumption of BLE is further important because nodes like smartphones have limited battery. From these three points of view, we had investigated whether.
