Title Tweeting 'when online is off'? Opportunistically creating mobile ad-hoc networks in response to disrupted infrastructure Type Conference Article
Year 2014 Publication ISCRAM 2014 Conference Proceedings – 11th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2014
Volume Issue Pages 662-671
Keywords Information systems; Peer to peer networks; Smartphones; Telecommunication networks; Disruptions; Infrastructure; Isolated islands; Mobile adhoc network (MANETs); Network infrastructure; Opportunistic communications; Peer-to-peer fashion; Two ways; Mobile ad hoc networks
Abstract In this paper, we present a system that enables people to post and receive tweets despite disruptions of existing network infrastructure. Our system opportunistically deploys mobile ad hoc networks (MANETs) based on Wi-Fi in which people can communicate with each other in a peer-to-peer fashion. A MANET per se constitutes an isolated island, but as people carry devices around that can join other MANETs, eventually people can transport previously collected data to the online world. Compared to other systems that aim to enable communication in crisis, our system differs in two ways: it does not rely on existing network infrastructure, and it exploits established protocols and standards allowing it to run on off-the-shelf, commercially available smartphones. We evaluated our prototype with a group of students and practitioners. Overall, we received positive feedback on the potential of our technology, but also were pointed to limitations requiring future work.

Title A geo-based application for the management of mobile actors during crisis situations Type Conference Article
Year 2008 Publication Proceedings of ISCRAM 2008 – 5th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2008
Volume Issue Pages 219-229
Keywords Civil defense; Disasters; Geographic information systems; Information systems; Mobile devices; Mobile telecommunication systems; Risk management; Web services; Crisis situations; Emergency management; Geographic information; Manet; Outdoor environment; Peer to peer; Pervasive computing applications; Transparent access; Mobile ad hoc networks
Abstract The widespread availability of network-enabled handled devices has made the development of pervasive computing applications an emerging reality particularly suitable for managing emergency/disaster situations. Moreover in emergency management scenarios, Geographic Information Systems (GIS) are gaining momentum for their capacity to capture, analyze and manage geo-referenced data. In this paper we discuss an architecture designed to support rescue teams operating in outdoor environments and equipped with mobile devices working in a P2P fashion within a Mobile Ad-hoc Network (MANET). Our system has been designed to effectively address the on-field working persons' need for geographic information that cannot be supplied by conventional paper-based maps. Our approach provides a transparent access to geo-information and to GIS functionalities, and it addresses issues specifically relevant to emergency management scenarios in open fields.

Title Cross-layer overlay synchronization in sparse MANETs Type Conference Article
Year 2008 Publication Proceedings of ISCRAM 2008 – 5th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2008
Volume Issue Pages 546-555
Keywords Information systems; Routers; Synchronization; Telecommunication networks; Cross layer optimization; Distributed events; Network partitions; Publish-subscribe; Rescue operations; Routing table; Sparse MANETs; Stable routing; Mobile ad hoc networks
Abstract Mobile Ad-Hoc Networks maintain information in the routing table about reachable nodes. In emergency and rescue operations, human groups play an important role. This is visible at the network level as independent network partitions which are for some time stable before their members change through merging or partitioning. We use the information from stable routing tables to optimize the synchronization of Mediators in a Distributed Event Notification System. In a stable partition each node has the same information, thus a single Mediator can efficiently coordinate the synchronization, while all other Mediators just receive updates. We show in our experiments that just a few seconds are needed until routing tables stabilize and all nodes have a common view of the partition. We present a heuristic to determine the proper time to synchronize. Furthermore, we show how exceptions, like disappearing coordinating Mediators and unexpected messages, can be efficiently handled.

Title Simulation of wireless, self-organizingandagent-based dynamic communication scenarios Type Conference Article
Year 2012 Publication ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2012
Volume Issue Pages
Keywords Information systems; Mobile agents; Agent-based communication; MANET routing; Mobile data; Self organizations; Simulation; Mobile ad hoc networks
Abstract The inter-disciplinary research project SpeedUp focuses on an IT framework to support communication and collaboration for mobile rescue forces. Starting with the investigation of methods, organizational structures and strategies a separation of the professional and technical (IT) layers is achieved. In most cases rescue activities are highly dynamic, so the choice of a MANET supports best the application of mobile agents and different routing strategies. Using simulation, a number of representative, location-based scenarios are analyzed and evaluated. © 2012 ISCRAM.

Title Intelligent system for exploring dynamic crisis environments Type Conference Article
Year 2006 Publication Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2006
Volume Issue Pages 288-297
Keywords Complex networks; Information systems; Intelligent systems; Mobile ad hoc networks; Multi agent systems; Crisis; Emergency; Graph matchings; Infrastructure-less; Manet; Map merging; Topological map; Merging
Abstract The routing in complex buildings is provided by information systems. But during a crisis situation, these systems may collapse due to certain incidents like an explosion, a fire or sabotage. The task of guiding people in this situation has to be handled in some way. In this paper we present a possible solution to this problem. We use a multi-agent system in a mobile ad-hoc network, without the need of any infrastructure. The main idea of the paper is that just by exploring the damaged building, the data of the changing environment becomes available and the challenge is how to fuse this data from different observers. We focused on the way of building, sharing and merging topological maps, using observations from individuals present in this infrastructure-less network. Besides a more efficient exploration of the building, the system presented in this paper can provide the rescue teams with additional services like finding the nearest exit. Some results of the tests we run with our system are also presented.
