A Comparative Study of Redundant Data Minimization and Event Coverage in Wireless Multimedia Sensor Networks (WMSNs)

In the modern era, data redundancy stands as one of the predominant problem existing in case of sensor networks. It basically takes place owing to the transmission of same data through multiple scalars lying at the superimposed zones of field of views. Such scalars report the prevailing event information multiple times to various camera sensors leading to redundancy in data transmissions. The main objective is to diminish such repeated data transmission while enhancing coverage of event region under consideration. This paper basically compares three approaches and the way they behave in presence of obstacles while diminishing redundancy and enriching the coverage of monitored zone.
