This paper presents an optimization framework to maximize the lifetime of wireless sensor networks for structural health monitoring with and without energy harvesting. We develop a mathematical model and formulate the problem as a large-scale mixed integer non-linear programming problem. We also propose a solution based on the Branch-and-Bound algorithm augmented with reducing the search space. The...
Sensor node placement optimization has a significant role in wireless sensor networks, especially in structural health monitoring. Since sensor node placement affects the routing, optimization should be Jointly done for the node placement and routing. The existing work separately optimizes the node placement and routing (by performing routing after carrying out the node placement). However, this approach...
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...
Wireless sensor networks (WSNs) have shown to be an efficient solution for physical parameters monitoring and activity detection. WSNs are usually designed using single optimization by optimizing one objective function such as energy consumption taking some constraints into consideration. In multi-objective optimization (MOPT) multiple and often conflicting objectives need to be optimized while satisfying...
