  1. Event Source Destination IRT – Internet Real-Time Lab • Affiliated with the Computer Science Department at Columbia University conducts research in the areas of Internet and multimedia services • Internet telephony, wireless and mobile networks, streaming, quality of service, resource reservation, dynamic pricing for the Internet, network measurement and reliability, service location, network security, media on demand, content distribution networks, multicast networks and ubiquitous and context-aware computing and communication. 7DS Project Objectives • In this project, we address both theoretical problems in data dissemination and practical implementation on Linux platform. • 7DS System Design • 7DS system is an architecture consisting of a set of protocols that enables resource sharing among peers that are not necessarily connected to the Internet. This system also enables mobile nodes to gather and relay messages all around the network. • 7DS Components • Proxy Server • Cache manager & Search engine • Multicast Query Server • SMTP Server & MTA Motivation 7DS is a peer-to-peer data sharing network that exploits node mobility for data dissemination. Any two nodes communicate when they are in proximity. Under this transmission constraint, any pair of nodes is intermittently connected as mobility shuffle node locations. Internet Real-Time LaboratoryArezu Moghadam and Suman SrinivasanColumbia University in the city of New York 7DS Overview 7DS is a disconnected wireless system with no global network connection. 7DS is an unattended network with dynamically changing topology with the goal of maximizing information dissemination and resource sharing among devices in the network. • 7DS Applications in the Real World • Mobile Sensing Application: • Data Sharing in Ad-Hoc Networks • Automated 3-D Site Modeling • Intelligent Mapping of Network Topology • Distributed Mobile and Wearable Augmented Reality Systems 7DS System 7DS System Architecture • Proxy Server listens to incoming HTTP Requests • Query Multicast is sent through a Query Listener & Scheduler • SMTP Server listens to the incoming messages and dumps them up to the MTA For More detailed information about this project please contact arezu@cs.columbia.edu.
