A Camera Node Wake-Up Algorithm for Wireless Sensor Networks

In wireless sensor networks, aiming at the problem that camera nodes consume more energy, a multi-node cooperative camera node wake-up algorithm based on image quality is proposed. A three-tier cooperative wireless sensor network structure model is adopted. Camera nodes are taken as a single layer. After common nodes monitor the event, the residual energy of camera nodes is taken as the main reference standard. Combined with the image quality, the multi-node fusion algorithm is used to determine the wake-up camera nodes. The simulation results show that, compared with the current wake-up algorithm of camera nodes, this algorithm prolongs the lifetime of camera nodes on the basis of guaranteeing image quality.
