Forest fires have recently been the most critical issue faced by the world. The huge environmental, economic, and societal damages caused by wildfires are hindrances to social development. The increasing figures of such instances since the last few years make it the need of the hour to start considering it on priority and take appropriate actions. For this, intense knowledge is required about the nature of forest fires, their causes and appropriate technology to be used. Wireless sensor networks have always been a preferable technology in such kind of disaster management and environmental monitoring scenarios. However, there are yet some prominent issues that affect the overall performance of wireless sensor networks, especially in harsh terrains like forests. In this paper, information has been provided about the causes, damages and aftereffects of forest fires. Moreover, a study has been conducted on various articles highlighting the issues and challenges being faced in wireless sensor networks. The paper further provides a simple and easily understandable analysis highlighting the types and priority of challenges. This would benefit the researchers in identifying the current research gaps in the field of wireless sensor networks, especially in applications like forest fire monitoring or environmental monitoring and disaster management.
