Kavitha. T, Poongodi. C . Modified Bubble Rap Routing for Intermittently Connected Networks. International Conference on Research Trends in Computer Technologies 2013. ICRTCT, 4 (February 2013), 35-38.
Intermittently connected mobile network (ICMN) is a delay-tolerant ad hoc network that is made up of mobile nodes. Here most of the time there does not exist a complete path from source to destination, or such a path is highly unstable and may break soon after it has been discovered. Extreme mobility may render a complete path discovery highly inefficient. In these networks, there is usually no supporting infrastructure for routing. Due to frequent network disruption and intermittent connections in ICMN, it is difficult to establish reliable end-to-end paths between mobile peers. Conventional routing schemes fail, as they try to establish complete end-to-end paths, before any data is sent. In a social network, nodes show group behaviors so that some nodes meet each other more frequently than others. Bubble Rap routing protocol is used to forward the message to the destination based on the two metrics such as Community and Centrality nodes. Global ranking and local ranking systems are calculated to forward the message thus providing higher delivery rates and shorter delivery delays in the ICMN.
