A Sensor-Actor Coordination protocol for Variable Rate Irrigation

In mobile automated Wireless Sensor and Actuator Network (WSAN), resource rich actors are responsible for data collection, decision making, and implementing control actions. Information collection from entire event region is the prerequisite for generation of control actions. However, random stopping locations and predefined time for data collection at stop point(s) can result in partial information collection of a region that in turn hampers the decision. In existing research works stopping time and location are either predefined or random that can be crucial to decision making process for the event region. To this end, this paper proposes an energy efficient sensor-actor coordination mechanism that ensures data collection from event region taking decision making aspects into account. Proposed algorithm takes challenges of Variable Rate Irrigation (VRI) under consideration. It calculates event region dependent stop locations and time for mobile actors that ensures data collection from entire event region.
