Abstract: In order to solve the tasks assignment of actuators in wireless sensor and actuator network (WSAN), an improved distributed auction algorithm (IDAA) is proposed. Utility of each task and cost of each actuator are taken into account to obtain the optimal assignment. The construction method of the response tree is improved, and the matching degree is introduced in the calculation of utility. Simulation results show that the energy consumption has been more balanced, and the numbers of data packets and time of tasks assignment have been reduced.

Key words: wireless sensor and actuator network, task assignment, auction algorithm, actuator-actuator coordination
