- Abstract
The firework algorithm is easy to fall into a local optimum in the application of node coverage for wireless sensor networks. In order to solve the problems of uneven distribution of nodes and slow convergence, a novel hybrid firework-virtual force algorithm based on the µ-law is proposed. Firstly, redefine the explosion operator with the aid of µ-law so that the number and amplitude of fireworks explosions will be dynamically adjusted by resizing the value of µ in different iterations, which means that fireworks are more diverse. Secondly, the virtual force is introduced to adjust the position information of sensor nodes in the stagnant fireworks, which can accelerate the evolution of the fireworks population. Through the above approaches, the improved algorithm can jump from the local optimal solution and accelerate convergence. Accordingly, the algorithm can avoid an uneven distribution of nodes in the application of node coverage. Simulation experiments demonstrate that the algorithm can significantly reduce the overlapping areas and monitoring blind areas of the network, and meanwhile, the algorithm effectively increases the node coverage and compresses the node moving distance.
