论文摘要
探索移动设备用户之间的社交连通性的临时社交网络（ASNET）正在成为当今互联网中最重要的形式之一。在这种情况下，资源稀缺环境中中间节点的最大带宽利用是具有挑战性的任务之一。传统运输控制协议（TCP）使用往返时间机制来共享用户之间的带宽资源。但是，它不会探索节点之间具有社会意识的属性，并且无法有效地区分无线网络中各种类型的数据包丢失。在本文中，提出了一种具有社会意识的避免交通拥堵方案，即利用中间节点之间的相似性与社会特性相匹配的胫骨，以提高ASNET的资源效率。胫骨对TCP进行有效的数据传输。在带宽资源分配过程中，它为ASNET链接上不同TCP连接之间最大匹配的兴趣相似性提供了高优先级。胫骨不需要在下层或接收器节点上进行任何修改。实验结果表明，与现有协议相比，胫骨的性能更好，从链接利用，不必要的减少拥塞窗口，吞吐量和重传比。
Ad-hoc Social Network (ASNET), which explores social connectivity between users of mobile devices, is becoming one of the most important forms of today's internet. In this context, maximum bandwidth utilization of intermediate nodes in resource scarce environments is one of the challenging tasks. Traditional Transport Control Protocol (TCP) uses the round trip time mechanism for sharing bandwidth resources between users. However, it does not explore socially-aware properties between nodes and cannot differentiate effectively between various types of packet losses in wireless networks. In this paper, a socially-aware congestion avoidance protocol, namely TIBIAS, which takes advantage of similarity matching social properties among intermediate nodes, is proposed to improve the resource efficiency of ASNETs. TIBIAS performs efficient data transfer over TCP. During the course of bandwidth resource allocation, it gives high priority for maximally matched interest similarity between different TCP connections on ASNET links. TIBIAS does not require any modification at lower layers or on receiver nodes. Experimental results show that TIBIAS performs better as compared against existing protocols, in terms of link utilization, unnecessary reduction of the congestion window, throughput and retransmission ratio.
