Abstract | This paper studies the optimal placement problem in structural health monitoring (SHM) using wireless sensor networks (WSN). This problem is formulated as a refined multi-objective optimization problem with various constraints of connectivity and flow conservation conditions, while minimizing the energy consumption and maximizing the information quality are the objectives. To perform the multi-objective optimization, we modify the heuristic single objective power-aware sensor placement using the effective independence model (p-SPEM) algorithm introduced in [1]. In this paper, we design and analyze a multi-objective p-SPEM (mop-SPEM) algorithm for sensor node placement. The multi-objective formulation adds more flexibility because the energy consumption and the information quality can be easily traded-off. The mop-SPEM is simulated and compared with p-SPEM for a nine-storey building. Results show that mop-SPEM is able to trade-off the energy with the information quality by adjusting the relative weights of the objective functions. |
