A Distributed Scalar Controller Selection Scheme for Redundant Data Elimination in Sensor Networks

摘要

This research presents a novel distributed strategy for actuation of reduced number of cameras motivated by scalar controller selection for eliminating the amount of redundant data transmission taking place in any geographic zone under speculation. The proposed framework is based on dividing the monitored region into a number of virtual compartments. A scalar controller is selected in each of the compartments, which is chosen in such a manner that its distance is the minimum among all the scalars from the central point of the concerned compartment. Further, all the cameras are arranged in a predetermined circular fashion. Whenever, an event takes place, the scalar controllers inform their respective cameras regarding its occurrence. The cameras collaboratively exchange information among themselves for deciding which among them are to be actuated. The least camera activation, enhanced coverage ratio, minimized redundancy ratio, reduced energy and power expenditure obtained from the experimental outcomes affirm the effectiveness of our proposed method over other approaches.
