蓝牙作为构建由个人设备组成的即时自组织网络的一种手段被认为很有吸引力。然而，由于扩频和非对称通信模型等技术特性，基于蓝牙的自组织网络引发了一些问题。在本文中，我们提出了一种考虑蓝牙技术特征的网络形成模型。所提出的模型确定了蓝牙系统必须实现以形成自组织网络的三个基本阶段，即（1）邻居发现、（2）邻居分组和（3）角色分配。每个阶段都会引入一些设计权衡，产生一个包含先前提出的设计和新设计的设计空间。基于这一观察，我们提出了一种新的自组织网络形成协议，称为 Bluestars。所提出的协议具有良好的特性，例如节点之间的平均距离较短、节点之间的可达性较高以及与添加新节点相关的开销较低，但它足够简单，可以在小型系统中实现。
Bluetooth is considered attractive as a means of building an instantaneous ad hoc network consisting of personal devices. However, Bluetooth-based ad hoc networking raises several issues due to the characteristics of the technology such as spread spectrum and the asymmetric communication model. In this paper, we propose a network formation model that considers the technical characteristics of Bluetooth. The proposed model identifies three essential phases that a Bluetooth system must implement to form an ad hoc network, namely, (1) neighbor discovery, (2) neighbor grouping, and (3) role assignment. Each of these phases introduces several design trade-offs, producing a design space that encompasses previously proposed designs as well as new designs. Based on this observation, we propose a new ad hoc network formation protocol called Bluestars. The proposed protocol has nice properties such as shorter average distance between nodes, higher reachability between nodes, and lower overheads associated with an addition of new nodes, yet it is simple enough to be implemented in a small system.
