The main constraint that affects the practical design of Wireless Sensor Networks (WSNs) is the network energy as network nodes has limited resources capabilities. Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol is one of the popular clustering based algorithms that optimize energy consumption of WSN. The selection of Cluster Heads (CHs) in each round is determined depending on a...
This paper studies the performance of Discrete Cosine Transform based Single Carrier Frequency Division Multiple Access (DCT-SC-FDMA) with image transmission. Also, we propose a Continuous Phase Modulation (CPM) based DCT-SC-FDMA structure for efficient image transmission. The proposed structure combines the advantages of excellent spectral energy compaction property of DCT based SC-FDMA, in addition...
Scanner identification is the ability to discern the devices by which an image was scanned. In this paper, a new and robustness individual source scanner identification scheme is proposed. This scheme formulates a unique fingerprint for each scanner using traces of dust, dirt, and scratches over scanner platen on scanned images. A single Support Vector machine (SVM) classifier is implemented and trained...
