摘要:

Ad-hoc社交网络(ASNET)探索移动设备用户之间的社交连接,正在成为当今互联网最重要的形式之一。在这种情况下,资源稀缺的环境中的中间结点的最大带宽利用率是具有挑战性的任务之一。传统的传输控制协议(TCP)使用往返时间机制来在用户之间共享带宽资源。然而,它没有探索节点之间的社会感知属性,并且不能有效区分无线网络中的各种类型的分组丢失。本文提出了一种社会感知的拥塞避免协议TIBIAS,利用中间结点之间的社会属性相似性匹配来提高ASNET的资源利用率。TIBIAS通过TCP执行有效的数据传输。在带宽资源分配过程中,优先考虑ASNET链路上不同TCP连接之间兴趣相似度的最大匹配。TIBIAS不需要在较低层或接收器节点上进行任何修改。实验结果表明,TIBIAS协议在链路利用率、拥塞窗口的不必要减少、吞吐量和重传率等方面均优于现有协议。

英文摘要:

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.
