It is becoming increasingly apparent that citizens are left helpless in the face of emergencies or disasters until such time as help can arrive from first responders. Even when such emergency response units finally make it to the disaster area, it takes considerable time to plan and execute search-and-rescue operations. Gladly, information and communication technologies are increasingly playing a critical role in alleviating this situation. Unfortunately though current solutions (predominantly designed upon infrastructure-based networks) lack flexibility and robustness needed to withstand outages commonly observed in emergency scenarios. On the other hand, ad-hoc solutions formed by opportunistic networking between casual devices (including handsets, tables, PDAs and the like) promise to deliver a far more effective solution. This presentation advocates for the latter approach, examines necessary design requirements and identifies current system limitations. Subsequently, the HelpNet networking architecture is introduced as a novel approach to address those issues that arise from a plausible ad-hoc emergency response networking paradigm. The presentation concludes with a review of enabling technologies that can be used to build HelpNet.
