Application of Distributed Wireless Sensor Network on Humanitarian Search and Rescue Systems

Abstract

Humanitarian search and rescue operations can be found in most large-scale emergency operations. Search and rescue technology to-date still rely on old technologies such as search dogs, camera mounted probes, and technology that has been in service for decades. Intelligent robots equipped with advanced sensors are attracting more and more attentions from researchers and rescuers.This paper presents the design and application of a distributed wireless sensor network prototyping system for tracking mobile search and rescue robots. The robotic system can navigate autonomously into rubbles and to search for living human body heat using its thermal array sensor. The wireless sensor network helps to track the location of the robot by analyzing signal strength. Design and development of the network and the physical robot prototype are described in this paper.
