A Localization Algorithm for Disaster Situation Using Flying Sensor Nodes

Due to many reasons wireless sensor networks are preferred to tackle disaster situation 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 humans 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 sensors.
