A novel approach using optimum camera actuation in event boundary detection method for redundant data minimization

Abstract

The necessity of having optimum camera activation is rapidly increasing in distributed environment as well as wireless sensor networks. In the current research, we have studied the event boundary detection approach for redundant data minimization by actuating less number of cameras. The study reveals that some of the cameras those are present outside the exact event boundary are activated unnecessarily being informed from the boundary scalars regarding the event occurrence. This unnecessary activation of outer cameras leads to additional energy expenditure and redundant data transmission. In this paper, we have proposed a novel approach to maintain such unnecessarily actuated cameras in turned off state. The experimental evaluation in terms of less camera activation, minimized redundancy ratio, enhanced coverage ratio and reduced energy consumption, obtained from the investigation justifies the effectiveness of the proposed approach as compared to another approach recently proposed in the literature.
