The bluetooth technology provides a point-to-point communication interface to mobile phones and other electronic devices, which can be used to form a self-organized ad hoc mesh network consists of mobile phones. In such a self-organized mesh network, the data packets are not transferred by traditional telecommunication backbone network but through bluetooth-based hop-by-hop routing among mesh nodes in the network. Such an ad hoc mesh network may find a wide span of application scenarios where access to backbone network infrastructure is not available, yet it needs an efficient routing protocol to provide a timely transmission mechanism for data packets to reach their destination even under situations when network topology is in constant changes due to mobile node’s movement. In the bluetooth-based device-to-device routing protocol (BDRP) presented in this paper, we propose several key designs as processed data table, node exclusion by packet and source control routing to provide an end-to-end packet transmission solution in a dynamically changing topology with constraints on network bandwidth, battery power, and storage space on a mobile device. The processed data table and node exclusion by packet mechanisms contribute to eliminating a great number of non-useful duplicate packets in routing path, and the source control routing algorithm implemented with a cross-layer packet retransmission process provides a fast and low-overhead routing policy and an assurance to packet reaching destination. In the simulation experiment conducted BDRP demonstrates its effectiveness and efficiency in eliminating undesirable duplicate packets and adaptability to constant topological changes. The performance comparison experiment indicates that the BDRP outperforms the optimized link state routing (OLSR) protocol in packet arrival rate, particularly under situations when mobile nodes are in fast moving mode, yet manages to maintain the same level of transmission delay as OLSR’s even with the packet retransmission process. The work presented in this paper provides a key technology for the applications of Bluetooth mobile phone mesh network in a larger geographic area and a broader application domain.

蓝牙技术为移动电话和其他电子设备提供了点对点通信接口，可用于形成由移动电话组成的自组织自组织网状网络。在这种自组织的网状网络中，数据分组不是通过传统的电信骨干网传输的，而是通过网络中网状节点之间基于蓝牙的逐跳路由来传输的。这样的自组织网状网络可能会发现无法访问骨干网络基础结构的广泛应用场景，但是它需要有效的路由协议为数据包提供及时的传输机制，以便数据包即使在网络拓扑结构下也能到达目的地。由于移动节点的移动而不断变化。在本文提出的基于蓝牙的设备到设备路由协议（BDRP）中，我们提出了一些关键设计，例如处理后的数据表，按包进行节点排除和源控制路由，以提供端到端的包传输解决方案。动态变化的拓扑，对移动设备的网络带宽，电池电量和存储空间有限制。数据包机制处理的数据表和节点排除机制有助于消除路由路径中的大量无用重复数据包，并且使用跨层数据包重传过程实现的源代码控制路由算法提供了一种快速且开销低的路由策略并保证包到达目的地。在进行的模拟实验中，BDRP证明了其消除不必要的重复数据包以及对不断变化的拓扑结构的适应性的有效性和效率。性能比较实验表明，BDRP在数据包到达率方面胜过优化的链路状态路由（OLSR）协议，尤其是在移动节点处于快速移动模式但仍设法保持与OLSR相同水平的传输延迟的情况下。分组重传过程。本文提出的工作为蓝牙手机网状网络在更大的地理区域和更广阔的应用领域中的应用提供了一项关键技术。性能比较实验表明，BDRP在数据包到达率方面胜过优化的链路状态路由（OLSR）协议，尤其是在移动节点处于快速移动模式但仍设法保持与OLSR相同水平的传输延迟的情况下。分组重传过程。本文介绍的工作为蓝牙手机网状网络在更大的地理区域和更广阔的应用领域中的应用提供了关键技术。性能比较实验表明，BDRP在数据包到达率方面优于优化的链路状态路由（OLSR）协议，特别是在移动节点处于快速移动模式但仍设法保持与OLSR相同级别的传输延迟的情况下。分组重传过程。本文介绍的工作为蓝牙手机网状网络在更大的地理区域和更广阔的应用领域中的应用提供了关键技术。
