Integrating Smart Phones into Emergency Networks via Wi-Fi Tethering

13 Apr

Krishna Kant, Temple University, USA

External Presentation (External Speaker)

In this talk, I will discuss an architecture called Energy Aware Disaster Recovery Network using WiFi Tethering (E-DARWIN). The underlying idea is to seamlessly integrate mobile devices carried by the people in a disaster area into the emergency response network by exploiting the WiFi tethering capability that is ubiquitously available in nearly all smartphones already. The emergency network is assumed to consist of especially deployed Wi-Fi access points to connect to smartphone clusters and other backend infrastructure. The vision of such a network is to provide an agile, semi-automated mechanism to engage the smartphones and their sensors for collecting and transmitting data from its surroundings for rescue and disaster assistance purposes. We study the issues of application initiation, device discovery, data collection, and minimum delay data routing in such a network. We also analyze a distributed coalition formation game for distributing the data capturing task among wireless device based on data redundancy and device characteristics (capabilities, available energy, and network participation). We evaluate the performance of the proposed architecture using a prototype application implemented on Android platform and large-scale simulations. I will also talk about the future directions of the research including dynamic evolution of the network as dictated by the emergency situation.
