Wireless Sensor and Actor Networks (WSANs) are distributed wireless networks of heterogeneous devices referred to as sensors and actors. In Wireless Sensor and Actor Networks (WSANs) the collaborative operation of sensors enables the distributed sensing of physical phenomenon, while actors collect and process sensor data and perform appropriate actions. Sensors are low-cost, low-power, multi functional devices that communicate in short distances. Actors are resource-rich devices equipped with high processing capabilities, high transmission power and long battery life.
