A Simple Grid-Based Localization Technique in Wireless Sensor Networks for Forest Fire Detection

This research aims to develop a new sensor-based localization technique which is exclusively used for forest fire detecting systems. Our algorithm addresses three key criteria of forest fire detecting systems deployed in nature, which are: low complexity, high efficiency and low power consumption, by the 2 features: estimating a grid-based output and adopting an event-triggering mechanism. The algorithm´s low complexity and high efficiency is indicated by its average-case running time of O(N_a) - where N_a is the number of anchors. Despite of being simple, our proposed technique can achieve a good performance in terms of outputted region´s area, such as: More than 60% of inputs can result in a small-enough region-based output for monitored fields with dimension up to 6 times of sensors´ transmission range.
