摘要:: 针对车载社交网络(VSN)是动态变化的原因,导致车与车之间的连通性不稳定、互相通信延迟太大,提出了一种异构网络框架中的连接管理技术(connection management techniques in hetero-geneous Network frameworks,CMTHNF)。它遵循异构无线社交网络,由在线社交网络(online social networks,OSN)和 VSN 组成,OSN 和 VSN 可以同时存在,用于在属于不同网络节点之间进? 行数据交换,在预期的连接丢失以及网络性能下降的情况下,允许网络连接进行切换(即由 VSN切换到 OSN 或由 OSN 切换到 VSN),防止连接漏洞或流量过载,将消息从一个网络重定向到另一个? 网络。与传统的客户端-服务器(CS)和点到点(P2P)架构模式相比,CMTHNF 框架的性能远远优于单独的 VSN 网络,解决了目前研究的切换不仅不能提高性能,而且会达到一个上限,不必要的切换还会造成通信延迟和资源浪费的问题。因此,在连接性和延迟方面,CMTHNF 解决了 VSN 连接切换时性能下降和数据传播问题。

Abstract:: Aiming at the dynamic change of vehicle-mounted social network (VSN),which leads to unstable connectivity between vehicles and too large communication delay, we propose a connection management technology in a heterogeneous network framework(CMTHNF),which follows heterogeneous wireless social networks and consists of online social networks (OSN) and VSN.An OSNand a VSN can exist at the same time for data exchange between nodes belonging to different networks. In the case of expected connection loss and network performance deterioration, the OSN and VSN can be used for data exchange between nodes belonging to differentnetworks. Allows network connections to be switched (that is,from A VSN to an OSN or from an OSN to a VSN),preventing connection vulnerabilities or traffic overloads and redirecting messages from one network to another. Compared with traditional client-server(CS) and point-to-point (P2P) architectures,the performance of CMTHNF framework is much better than that of the single VSN network,which solves the problem that the current research on switching not only can not improve the performance,but also reaches an upper limit,and unnecessary switching will cause communication delay and resource waste. Therefore,in terms of connectivity and latency,the proposed framework CMTHNF addresses the performance degradation and data propagation issues of VSN connection switches.
