Abstract: For further reducing energy consumption and delay time and prolonging the survival time of node in wireless sensor networks,an improved Quantum-behaved Particle Swarm Optimization algorithm was proposed,which is applied to QoS multicast routing problem in wireless sensor networks.The algorithm finds the optimal routing which meets the threshold limit by using the fitness function and global best position update method in wireless sensor networks.The comparison of simulation experiment shows that this algorithm achieves good results in saving energy consumption,controlling delay time and prolonging the survival time of the network node.
