Disaster situations require a prompt emergency response. The failure of the legacy (wired) emergency response systems to efficiently cope in such time-critical environments has led to a great interest in wireless-based emergency response systems. In this regard, a number of wireless technologies and systems - each with its peculiar characteristics and pros and cons - have been proposed for use in various emergency response situations. This paper presents, to the best of our knowledge, the first comprehensive survey of the research on this practically important topic. We motivate the use of wireless technology for emergency response and present a comparative analysis of the available wireless technologies. After outlining the scope and requirements of emergency response systems, we provide an overview of the architectures and features of wireless-based emergency response systems and then compare …
