Wireless Sensor Networks (WSNs) are critical for applications like Structural Health Monitoring (SHM) and military surveillance. However, energy depletion in sensor nodes, especially in harsh environments where batteries cannot be easily replaced, remains a primary challenge. This work focuses on two optimization fronts: location optimization to reduce the number of sensors while maintaining high information quality, and energy optimization through efficient routing. A new algorithm, Higher Information Oriented Genetic Algorithm (HIOGA), is proposed to optimize sensor placement based on the Fisher Information Matrix (FIM).
