چکیده
Energy efficiency plays an important role in wireless sensor networks. All nodes in sensor networks are energy constrained. Clustering is one kind of energy efficient algorithm. To organize the nodes in better way a virtual backbone can be used. There is no physical backbone infrastructure, but a virtual backbone can be formed by constructing a Connected Dominating Set (CDS). CDS has a significant impact on an energy efficient design of routing algorithms in WSN. CDS should first and foremost be small. It should have robustness to node failures. In this paper, we present a general classification of CDS construction algorithms. This survey gives different CDS formation algorithms for WSNs.

Abstract— The last decade has witnessed a growing demand for wireless radio spectrum due to the rapid deployment of new wireless devices and applications. Spectrum is a precious resource and thus underutilization of a large part of allocated spectrum is not acceptable. Cognitive Radio(CR) is proposed as a promising solution for increasing spectrum utilization. We conduct simulations to validate...

Image compression is the reduction or elimination of redundancy in data representation in order to achieve reduction in storage and communication cost. For this we use the simple computational method, 2D-DCT, using two 1D-DCT performed on matrix of (8X8). The DCT is a technique that converts a signal from spatial domain to frequency domain. Here we first convert the image into minimum code unit...
