In this book, definition, development and evaluation of Autonomous Wireless Sensor Actuator Network (AWSAN) is discussed. Firstly the central and distributed systems are described. Then characteristic for autonomous system are considered. Based on the feedback model it is explained how the autonomous concept is applied in sensor actuator network. In order to develop an autonomous network a target-oriented routing algorithm is invented, called SCAR. To implement the AWSAN into automation process application, a method to find an optimal sample number for the sensor is introduced. By...
