分布式网络中的数据分发

Data Dissemination in Opportunistic Networks

Radu Ciobanu, Ciprian Dobre

摘要:

集成无线短距离通信技术的移动设备使得自发通信、交互和协作的新应用成为可能。一种有趣的方法是在移动设备无法建立直接通信路径时使用协作来促进通信。当移动设备在用户非常接近的情况下相互通信时形成的协作网络可以帮助应用程序在这种情况下仍然交换数据。在机会网络中,路由是动态建立的,因为每个移动终端根据存储-携带-转发范例进行操作。因此,移动设备之间的联系被视为向目的地移动数据的机会。在这样的网络中,数据传播使用转发来完成,并且通常基于发布/订阅模型。数据的传播也引起了有关用户隐私和激励措施的问题。各种机会性数据传播技术以不同方式解决这些问题。在本文中,我们分析了现有的相关工作在机会网络的数据传播领域。我们提出了一个建议的分类,捕捉在这样的网络中使用的数据传播技术的能力的类别。此外,我们调查相关的数据传播技术,并使用建议的分类法进行分析。

英文摘要:

Mobile devices integrating wireless short-range communication technologies make possible new applications for spontaneous communication, interaction and collaboration. An interesting approach is to use collaboration to facilitate communication when mobile devices are not able to establish direct communication paths. Opportunistic networks, formed when mobile devices communicate with each other while users are in close proximity, can help applications still exchange data in such cases. In opportunistic networks routes are built dynamically, as each mobile device acts according to the store-carry-and-forward paradigm. Thus, contacts between mobile devices are seen as opportunities to move data towards destination. In such networks data dissemination is done using forwarding and is usually based on a publish/subscribe model. Opportunistic data dissemination also raises questions concerning user privacy and incentives. Such problems are addressed differently by various opportunistic data dissemination techniques. In this paper we analyze existing relevant work in the area of data dissemination in opportunistic networks. We present the categories of a proposed taxonomy that captures the capabilities of data dissemination techniques used in such networks. Moreover, we survey relevant data dissemination techniques and analyze them using the proposed taxonomy.
