社会感知的转发:内容感知还是遗忘?

Social-aware Forwarding in Opportunistic Wireless Networks: Content Awareness or Obliviousness?

Waldir Moreira, Paulo Mendes

摘要:

在当前基于主机的Internet架构中,网络在动态场景中面临限制,主要是由于主机移动性。ICN范例通过释放在数据传输的生命周期期间建立端到端传输会话的需要来减轻这样的问题。此外,ICN的概念解决了互联网架构和用户使用互联网的方式之间的不匹配:目前,当用户只想获取数据时,他/她需要知道参与通信的主机的拓扑位置,而不考虑其位置。大多数研究工作的目标是在固定网络中提出一个稳定的ICN架构,在ad-hoc和车载网络中的例子很少。然而,互联网正变得越来越普遍,具有强大的个人移动设备,其允许用户形成动态网络,在动态网络中,可以始终以低成本交换内容。这样的普及无线网络遭受不同程度的中断,考虑到用户移动性、物理障碍、缺乏合作、间歇性连接等。本文讨论了内容知识(例如,类型和利益相关方)和机会网络中的社会意识,以推动在破坏性网络场景中部署ICN解决方案。考虑到这一目标,我们去了几个例子的社会意识的基于内容的机会主义网络的建议,考虑社会意识,让内容传播独立的网络中断的水平。要显示多少内容的知识可以提高基于社会的解决方案,我们说明了通过模拟一些内容不经意/面向的建议,在场景中的合成移动模式和真实的人类痕迹的基础上。

英文摘要:

With the current host-based Internet architecture, networking faces limitations in dynamic scenarios, due mostly to host mobility. The ICN paradigm mitigates such problems by releasing the need to have an end-to-end transport session established during the life time of the data transfer. Moreover, the ICN concept solves the mismatch between the Internet architecture and the way users would like to use it: currently a user needs to know the topological location of the hosts involved in the communication when he/she just wants to get the data, independently of its location. Most of the research efforts aim to come up with a stable ICN architecture in fixed networks, with few examples in ad-hoc and vehicular networks. However, the Internet is becoming more pervasive with powerful personal mobile devices that allow users to form dynamic networks in which content may be exchanged at all times and with low cost. Such pervasive wireless networks suffer with different levels of disruption given user mobility, physical obstacles, lack of cooperation, intermittent connectivity, among others. This paper discusses the combination of content knowledge (e.g., type and interested parties) and social awareness within opportunistic networking as to drive the deployment of ICN solutions in disruptive networking scenarios. With this goal in mind, we go over few examples of social-aware content-based opportunistic networking proposals that consider social awareness to allow content dissemination independently of the level of network disruption. To show how much content knowledge can improve social-based solutions, we illustrate by means of simulation some content-oblivious/oriented proposals in scenarios based on synthetic mobility patterns and real human traces.
