The improvement of the level of modernization of forest fires monitoring using information and communication technologies has strategic significance for many countries where forest fires occur frequently. Compared with the traditional techniques of forest fires detection, wireless sensor networks (WSNs) technology is a very promising green technology for the future in detecting efficiently the forest fires. In this paper we propose a comparative study between two forest fires detection methods (Canadian and Korean) using a real experimental approach. The methodology adopted for this study is provided. The related hardware schemes and implemented algorithms are given in detail for both methods. Through the preliminaries results, we conclude the effectiveness of the Canadian approach in terms of energy consumption and execution speed, and its suitability to the context of our country.
