带外多跳终端直通(D2D)网络是一种重要的移动通信平台,传统的多跳D2D网络拓扑控制方法复杂度高且可靠性差。文章以iptables工具为基础,提出了自动式多跳D2D网络拓扑控制方法 ATCBI。与传统方法不同,ATCBI中拓扑控制中心根据用户期望的网络拓扑生成控制消息,而手机终端则根据控制消息自动调用iptables工具并设置相应参数规则,实现网络拓扑控制。文章所实现的拓扑控制系统验证了ATCBI的有效性。实验结果表明,ATCBI能够有效减少多跳D2D网络拓扑控制的复杂度并提高可靠性。
Out-of-band Multi-hop Terminal Direct (D2D) network is an important mobile communication platform. The traditional multi-hop D2D network topology control method has high complexity and poor reliability. Based on the iptables tools, this paper presents ATCBI, an automatic control method for multi-hop D2D network topology. Unlike the traditional method, Topology Control Center in ATCBI generates control messages according to the user’s desired network topology, and the mobile terminal automatically invokes the iptables tools and sets the corresponding parameter rules according to the control messages to achieve network topology control. The topology control system implemented in this paper validates the validity of ATCBI. The experimental results show that ATCBI can effectively reduce the complexity of multi-hop D2D network topology control and improve reliability.
