Abstract:

Two-dimensional target coverage is a key issue in wireless sensor networks. A good coverage algorithm can effectively improve the monitoring effect of wireless sensor networks. Aiming at the two-dimensional target coverage problem, a new quantum annealing algorithm is proposed, and the corresponding system model is designed. The objective function of coverage optimization is also given. Aiming at the problem of running stagnation in the past heuristic algorithms, a new solution set generation method, quantum revolving gate, qubit measurement method and qubit state update method are designed for the quantum annealing algorithm, which accelerates the convergence speed of the algorithm. The method based on the quantum annealing algorithm is compared with particle swarm optimization and ant colony optimization. Simulation results show that compared with the particle swarm optimization algorithm and the ant colony optimization, the proposed algorithm can effectively improve the quality of the solution, with the number of detected targets greatly improved.

Key words: wireless sensor networks, quantum simulated annealing algorithm, target coverage, particle swarm optimization, ant colony optimization
