A MANET protocol for information gathering from disaster victims

Abstract

In this paper, we propose and evaluate a MANET system to pursue the location and personal information of victims in disaster occurrence where we do not assume any fixed network infrastructures. Our proposing method gathers the information from victims' terminals with GPS receivers using ad-hoc communication through victims' terminals and vehicles. In our system, the disaster area is divided into grids and the data will be cooperatively held by the mobile terminals in each area. If the capacity to hold the data in an area is not enough, apart of the data will be relocated to neighbor areas. We have simulated our system in focus of information gathering rates and information keeping rates. Our experimental results show that the proposed system works effectively
