Methods to retrieve images involve retrieving images from the database by using features of it. They are colour, shape, and texture. These features are used to find the similarity for the query image with that of images in the database. The images are sorted in the order with this similarity. The article uses intra- and inter-texture chrominance and its intensity. Here inter-chromatic texture feature is extracted by LOCTP (local oppugnant colored texture pattern). Local binary pattern (LBP) gives the intra-texture information. Histogram of oriented gradient (HoG) is used to get the shape information from the satellite images. The performance analysis is land-cover remote sensing database, NWPU-VHR-10 dataset, and satellite optical land cover database gives better results than the previous works.

In wireless sensor networks, the data transmission provides the source of the data and the details of the forwarding data for the data packet through the based station, to save the energy and maximize the bandwidth while data transmission, the data packet is compressed at every node using the arithmetic coding technique. The encoding and decoding techniques are utilized for providing the secured data transmission. In this paper, the proposed Unique Data Identification System (UDIS) is used to generate the data communication model for user based validation technique. The proposed approach is capable of proxy interpretation for enhancing the server to get the solution for user authentication issues and processing the requests from the user. The performance evaluation is conducted using the network simulator to increase the performance in terms of user load and response time.
