-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)
Dual-Tree Complex Wavelet Transform is relatively a recent improvement of the Discrete Wavelet Transform (DWT) with important additional properties like shift invariant and directionality. In this paper, we propose a blind watermarking scheme based on Complex Double Haar Wavelet Transform (CDHWT). Single level CDHWT is applied on host image, it decompose(More)
Wireless Sensor Networks (WSN) constitute a special class of wireless data communication networks. In wireless sensor networks, sensor nodes are randomly deployed. Since the sensor nodes are required to operate under remote conditions without fresh supply of power to replenish itself, energy conservation becomes the major constraint. This necessitates the(More)
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)
