DTN是一种间歇性连接的无线自组织网络，由于传统的存储-前向消息在不连接的集群上传播，造成了长时间的可变延迟。为了减少端到端延迟并提高可靠性，本工作提出了一种基于社交的广播消息传播协议，该协议将远程通信与广播相结合。为了提高可靠性，我们提出了一种重播节点选择机制来增加接收节点的数量。为了评估我们提出的方法的性能，我们进行了广泛的仿真，研究了在大型移动网络中，我们提出的方法和贪婪流行病路由方法的消息传播效率，包括渗透率和可达性。大量的仿真结果表明，该方法具有实用性、可扩展性和高性价比。
DTN is an intermittently connected wireless ad hoc network with long and variable delay caused by the traditional store-carry-forward message dissemination over disconnected clusters. To reduce the end-to-end delay and increase reliability, this work proposes a Social-Based Broadcasting message dissemination protocol which incorporates long range communication with broadcasting. To increase reliability, we propose a rebroadcast node selection mechanism to increase the number of received nodes. To evaluate the performance of our proposed method, we conduct extensive simulation to investigate message dissemination efficiency, including penetration rate and reachability, of the proposed method and the greedy epidemic routing method in a large mobile network. The extensive simulation results demonstrate that our proposed method is practical, scalable and cost-effective for message dissemination in DTNs.
