An Efficient Data Redundancy Reduction (EDRR) scheme extending the life time of sensor nodes on wireless sensor networks has been proposed in this paper. Normally, in Wireless Sensor Networks (WSN), more energy is needed for transmitting data. In our earlier work, conjugative sleep scheduling scheme with Connected Dominating Set (CDS) for parent selection… (More)
This paper discuss proposed model for an energy efficient smart wireless multi-nodal sensor network. It is used for the collection of greenhouse related parameters at different locations inside and outside the greenhouse. The sensing nodes are the independent embedded system units which calculate sensing parameters under observation and measures them at… (More)
In this study an efficient copyright protection scheme for e-governance documents has been proposed. The proposed method uses Discrete Cosine Transform (DCT) and Principal Component Analysis (PCA) to watermark the digital content. Experimental results show that the proposed method offers high imperceptibility and also the watermark is extracted perfectly.
The important issue that is to be discussed in many applications involving Wireless Sensor Network (WSN) is the power efficiency and data aggregation. In this paper, an Efficient Data Redundancy Reduction (EDRR) scheme along with conjugative sleep scheduling algorithm has been proposed. In the existing Localized Power Efficient Data Aggregation Protocol… (More)
