A new ant routing algorithm based on Energy*Delay model(ED ANTS) was proposed utilizing the characteristic of wireless sensor network to solve the problems of energy consumption and real-time data transmission in distributed wireless sensor network.Artificial ants exchanged data,collected neighbor node statement and network routing information in the mode of online delay,then the best routing table was constructed to minimize the time delay in transferring a fixed number of data in an energy-constrained manner in one round.The reinforcement learning(RL) algorithm was employed to train the model for the energy consumption and the transmission delay are two relative independent characteristic quantities in wireless network system.Simulation results show that the algorithm performs twelve times better than low-energy adaptive clustering hierarchy(LEACH) and three times better than power-efficient gathering in sensor information system(PEGASIS) in terms of energy cost and delay per round.
