Haggle: a data-centric network architecture for mobile devices
Proceedings of the 2009 MobiHoc S3 workshop on MobiHoc S3(2009)
摘要
Delay-tolerant and opportunistic networks relax the traditional assumption of end-to-end connectivity. Such networks are therefore suitable for content dissemination in sparsely connected regions of the world, and for complementing existing infrastructure by operating cost-free, high bandwidth, albeit high latency, content delivery services. In this work we argue, however, that content dissemination in the above contexts requires us to revisit delay-tolerant communication at the architectural level, looking at multiple issues such as naming and addressing, congestion control and application interfaces. We propose a new architecture, called Haggle, that leverages the principles of search, as known from desktop operating systems and the Web, in order to achieve truly data-centric communication. Searching is naturally data-centric and embeds principles, such as ranking, that can be used to bind data to interested receivers and to prioritize the data to send during node encounters. We herein give an overview of the Haggle architecture and its basic design.
