Global climate change is increasing the occurrence of extreme climate phenomenon with increasing severity, both in terms of human casualty as well as economic losses. Authorities need to be better equipped to face these global truths. This paper reviewed a technological solution for search and rescue operations using wireless sensor networks (WSN). WSN is able to provide more efficient search and rescue operations and lessening the risk faced by rescuers. In this paper the design issues and existing WSN for search and rescue projects are reviewed.
