In wireless sensor and actuator networks (WSANs), whenever an event occurs in the physical world, sensors gather this information and forward it to actuators which are responsible for taking prompt decisions and react accordingly. To ensure an efficient action, an anycast routing mechanism is trivial, a sensor node wishes to report event information to any actuators in the network and one of them is selected to react in the area of interest. In this paper, we propose a multi-actuators based anycast routing protocol for wireless sensor and actuator networks which guarantees a minimum communication delay and consumed energy. We perform an overall evaluation of our proposed approach through simulations. The obtained results show out performance of our approach while providing effective gain in terms of communication delay and consumed energy.
