Abstract

This paper presents optimization of router deployment based on genetic algorithm for energy-constrained wireless sensor networks which are used for wildfire monitoring. The router positions are optimized so that the total communication distance is minimized to maximize the lifetime of the sensor network. To consider the real geographical features of the target field, the elevation differences are included in fitness evaluation. It is shown that one can reduce the total communication distance as well as the number of disconnected sensors for both flat and irregular terrains using the present optimization method.
