  Abstract Communication and interoperability between different organizations of first responders has been a problem for a long time. There have been examples of failure in communication between different organizations at World Trade Center on 9/11, for example some of the police warnings were not heard by fire fighters that resulted in several lives lost. In most cases, network unavailability or incapability of coordination among networks causes much damage. Therefore, we present a highly reliable communication infrastructure that is suitable at ground zero where the existing communication network is damaged or unavailable. We used Hybrid Wireless Mesh Network (HWMN) as a candidate for communication infrastructure with the capability of working in a heterogeneous environment with different available backhaul technologies. In addition to the use of WMNs, we also present some special requirements for a cellular networks generated by simulation models investigating different scenarios that occur at ground zero. For example, when hurricane Katrina hit New Orleans, people outside the ground zero area could place a call, but were not able to receive phone calls. This happened because the cellular network elsewhere was not able to contact the Home Location Register (HLR), located at New Orleans. We, in this paper, propose a solution in which the important user or network information databases such as HLR and VLR (Visitor Location Register) are replicated to provide a sufficient amount of fault tolerance.

  Title A wireless mesh infrastructure deployment with application for emergency scenarios 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 484-494  
  Keywords Disasters; Equipment testing; Information systems; MESH networking; Communication infrastructure; Emergency communication; Field data; Heterogeneous environments; Infrastructure deployments; Performance evaluation; Real-world scenario; Reliable communication; Emergency services  
  Abstract When a disaster or emergency occurs, one of the most pressing needs is to establish a communication network for the first responders at the scene. Establishing and accessing a reliable communication infrastructure at a crisis site is crucial in order to have accurate and real-time exchange of information. Failure in the exchange of timely and crucial information or delay in allocating resources impedes early response efforts, potentially resulting in loss of life and additional economic impact. At a disaster site, the existing communication infrastructure may be damaged and therefore partially or totally unavailable; or, there may not have been previously existing infrastructure (as in the case of remote areas). A communication infrastructure within the context of emergency applications should be reliable, easily configurable, robust, interoperable in a heterogeneous environment with minimum interdependencies, and quickly deployable at low cost. A disaster scene is a chaotic environment which requires a systematic approach to abstract the system, study the flow of information and collaboration among different disciplines and jurisdictions to facilitate response and recovery efforts. We have deployed the wireless mesh infrastructure in several drills at the university campus and in the city as part of the California Institute for Telecommunications and Information Technology (Calit2) NSF-funded RESCUE project (Responding to Crises and Unexpected Events). To evaluate network performance and identify the source(s) of bottleneck, we have captured the network traffic. The lessons learned from test bed evaluations of the network based on real-world scenarios can be applied to future applications to enhance the network design and performance.
