A cooperative scheme of 3-D localization with flying wireless sensor nodes for disaster situations

Abstract

As disaster is an unpredictable hazard that has direct influence on the lives of human beings which need to be localized and rescued immediately in such situations and due to many reasons wireless sensor networks are preferred to tackle disaster situations but it is not possible to pre-deploy sensor networks everywhere and it may not be guaranteed that disaster won't affect the functionality of pre-deployed sensor networks. In this paper it is proposed that flying wireless sensor network is a potential candidate to handle such situation and can overfly hindrances easily. This network is used to search, detect and importantly localize targets that need to be rescued. In this paper we have used trilateration in 3-D and propose that how location information can be accurately transferred from one search area to another using flying wireless sensor nodes, moreover we have compared flying wireless sensor network with mobile wireless sensor network and mobile robot network in terms of localization accuracy, network localization time and energy consumption.
