Lifeline: Emergency Ad Hoc Network
Lifeline is a group of systems designed for mobile phones and battery powered
wireless routers for forming emergency Ad hoc networks. Devices installed with
Lifeline program can automatically form Ad hoc networks when cellular signal is
unavailable or disrupted during natural disasters. For instance, large scale
earthquakes can cause extensive damages to land-based telecommunication
infrastructures. In such circumstances, mobile phones installed with Lifeline
program can be used to send emergency messages by the victims who are trapped
under collapsed buildings. In addition, Lifeline also provides a function for
the rescuers to estimate the positions of the victims based on network
propagation techniques. Lifeline also has the ability to recover from partial
crash of network and nodes lost
Saving lives: design and implementation of lifeline emergency ad hoc network
This paper aims to propose a system for automatically forming ad hoc networks
using mobile phones and battery-powered wireless routers for emergency
situations. The system also provides functions to send emergency messages and
identify the location of victims based on the network topology information.
Optimized link state routing protocol is used to instantly form an ad hoc
emergency network based on WiFi signals from mobile phones of the victims,
backup battery-powered wireless routers preinstalled in buildings and mobile
devices deployed by search and rescue teams. The proposed system is also
designed to recover from partial crash of network and nodes lost.
Experimental results demonstrate the effectiveness of the proposed system in
terms of battery life, transmission distance and noises.
A novel message routing schedule is proposed for conserving battery life. A
novel function to estimate the location of a mobile device which sent an
emergency message is proposed in this paper
