A Quadrigeminal Scheme based on Event Reporting Scalar Premier Selection for Camera Actuation in Wireless Multimedia Sensor Networks

Abstract

In this article, we have proposed a novel quadrigeminal scheme for selecting event-reporting scalar premiers that inform the prevailing event information to their corresponding camera sensors while contributing maximal event area coverage along with minimal redundant data transmission. In this work, we have divided the monitored region into a number of sub-regions. Subsequently, each sub-region is further divided into smaller sub-regions. In each of the larger sub-regions, four scalar premiers are chosen in such a way that a single scalar premier exists in one smaller sub-region. Subsequently, the cameras are activated by matching their scalar premier ids with each other based on descending order of their total scalar premier count values. The efficiency of the proposed scheme has been verified by experimental investigation and comparative assessment against three well known existing algorithms. The least camera actuation, improved coverage ratio along with reduced values of event-loss ratio, redundancy ratio and energy expenditure obtained from the experimentation affirm the effectiveness of the proposed method.
