蓝牙移动自组织网络是基于蓝牙的终端之间的通信方法，并且已经进行了各种研究以在灾害中在诸如智能手机的移动的终端之间共享数据。近来，通过互补地使用低功耗蓝牙和经典蓝牙两者，已经提出了一种快速连接建立方法以减轻终端之间的连接建立定时的争用（以下称为“现有方法”）。虽然现有方法提高了两个终端之间的连接速度，但是在人口密集的区域中会出现以下问题：终端从其他终端接收太多的连接请求，并且成功连接的数量减少。结果，网络的数据分组递送率恶化。在本文中，我们提出了一种通过基于周围终端的信息控制发送连接请求的终端来更可靠地建立连接的方法（以下称为“我们提出的方法”）。我们提出的方法利用蓝牙低功耗广播收集周围终端的信息，它控制连接请求到每个终端的传输。我们已经进行了实验，使用Android终端和我们提出的方法和现有的方法之间的结果进行了比较。结果，我们已经证实，成功的连接数和数据包的交付率，我们提出的方法是优于现有的方法上级。
Bluetooth MANETs are Bluetooth-based communication methods between terminals, and various studies have been conducted for sharing data between mobile terminals such as smartphones in disasters. Recently, by using both Bluetooth Low Energy and Classic Bluetooth complementarily, a fast connection-establishment method have been pro-posed to mitigate the contention for the connection-establishment timing between terminals (hereinafter referred to as " the existing method"). Although the existing method improves the speed of connection between two terminals, the following problems occur in a densely populated area: a terminal receives too many connection requests from other terminals, and the number of successful connections decreases. As a result, the data packet delivery ratio of the network deteriorates. In this paper, we propose a method to establish a connection more reliably by controlling a terminal that sends a connection request based on the information of surrounding terminals (hereinafter referred to as “our proposed method”). Our proposed method utilizes Bluetooth Low Energy broadcast to collect information on surrounding terminals, and it controls the transmission of connection requests to each terminal. We have conducted experiments using an Android terminal and compared the results between our proposed method and the existing method. As a result, we have confirmed that the number of successful connections and the data packet delivery ratio of our proposed method are superior to those of the existing method.
