A Fuzzy-Based Method for Selection of Actor Nodes in Wireless Sensor and Actor Networks
Elis Kulla, Tetsuya Oda, Leonard Barolli · 2014
A group of wireless devices with the ability to sense physical events (sensors) or/and to perform relatively complicated actions (actors), is referred to as Wireless Sensor and Actor Network (WSAN). In WSANs, sensors gather information about the physical events, while actors perform appropriate actions upon the environment, based on the sensed data shared by sensors. In order to provide effective sensing and acting, a distributed local coordination mechanism is necessary among sensors and actors. In this work, we focus on actor selection problem and implement a fuzzy-based system. The system decides whether the actor will be selected for the required job or not, based on data supplied by sensors and actual actor condition. We use three input parameters: Type of Required Action (TRA), Distance to Event (DE) and Remaining Power (RP). The output parameter is Actor Selection Decision (ASD). The simulation results show that the proposed system decides the actor selection in order to have short delays, low energy consumption and proper task assignment.
