Aiming at different service quality requirements under different circumstances of wireless sensor network (WSN), harmony search (HS) algorithm is used to solve the lowdelay and low-energy double-objective optimization problem in wireless sensor networks.First, analyze the low-delay and low-energy model, and establish the objective function.Then, use the priority-based path encoding algorithm to update harmony memory iteratively while searching the optimal path.Finally, simulation of 100-node network is carried out by using Matlab.The results show that sensor network data transmission path can be controlled according to the users' needs of delay and power.
