For this, we need to have appropriate localization techniques that can be used in sensor nodes during these times. Scientists have developed new techniques recently that deal with the localization of remote nodes using positioning methods which involve deploying a GPS-based mobile anchor node that advances along the path and transmitting its position value regularly thus enabling its localization. Also, during localization, it is very important to keep in mind the energy consumption along the path. In this paper, we have focussed mainly on discrete amounts of energy that are consumed during different phases of localization like a start-up, motional as well as turning. Here we have proposed an algorithm combining path identifying algorithm, and location-identifying algorithm with the mobile anchor node based on tri-lateration techniqu...

Reduction of time complexity for the mathematical operations in Elliptic Curve Cryptosystems with minimum hardware resources, the methods: Addition and Subtraction, Mutual Opposite Form, and Complementary Recoding techniques proposed as fast scalar multiplication schemes. The fast-point multiplication method is always necessary for any mathematical operation on an Elliptic Curve Cryptosystem with a restricted system. This study compares the performance of fast-point multiplication algorithms in terms of computational and execution time to determine the quickest one. For any elliptic curve-related arithmetic operations, point multiplication has a vital role in reducing the idle time of hardware utilization. Rapid point multiplication is essential to minimize enhanced time complexity to determine the most suitable algorithm for mobile devices.

There is a large demand for OCR on hand written documents in Image processing. Even though, sufficient studies have performed in foreign scripts like Arabic, Chinese andJapa nese, only a very few work can be traced for handwritten character recognition mainly for the south Indian scripts. Optical Character Recognition (OCR) is technique to convert the scanned handwritten, typed or printed document into computer readable form. OCR system helps to digitize old documents, recognizing vehicle number plate and have various surveillance and forensic applications. OCR system development for Indian script has many application areas like preserving manuscripts and ancient literatures written in different Indian scripts and making digital libraries for the documents. Feature extraction and classification are essential steps of character recognition process affecting the overall accurac...

Healthcare information split across numerous silos adversely influences research activities and administrations. There were no reported cases of about half of the clinical preliminaries. The expense of medication disclosure is ever-expanding, and unsatisfactory and fake medicines are as yet an enormous issue. Blockchain has the potential to address such substantial problems. Blockchain technology is a distributed and secure database organized by various groups to store and offers a permanent online transaction record. Blockchain has numerous medicinal services applications and can improve mobile health applications, preliminary clinical information, and insurance information storage. Each of the blocks has an independent unit holding its report and a dependent link that makes regulated by participants who store and share the data without third-party intervention. The blockchai...

The social network will be a network of smart things which are clustered on the basis of a relation. in our work it is not a smart object rather a smart social object will make some difference in the improvement of the health care. The major goal of the work is to give a model of monitoring the condition of the patient and prediction of his or her health status. The approach of the work is based on various sensors. These heterogeneous sensors will give the data as a social network of things to form the social internet of things network. the sensor used here are PPG and GSR for it's ease to use and accuracy.

In Optical Character Recognition, the text lines in a document must be segmented properly before recognition. English Character Recognition (CR) has been extensively studied in the last half century and progressed to a level, sufficient to produce technology driven applications. But same is not the case for Indian languages which are complicated in terms of structure and computations. This is the motivation behind choosing OCR for Odia language. An odia handwritten paragraph is chosen for processing and recognition. The HOCR system is devised to first segment the whole document into text lines, then to words and then to individual characters. These characters are then used to extract the necessary features and recognize those characters and classify them.

As on recent studies, the handwritten character recognition (HCR) gaining more importance due to the increase in computational work. Various methods proposed for the identification of written characters. Selection of a relevant feature is probably the essential factor in achieving high recognition performance with much better accuracy in HCR system. Another critical challenge is that there was very less number of research done on Odia character. In this research work, we have used a multilayer feed-forward network with backpropagation for the recognition. Also, a few comparisons we have done on this scenario. In pre-processing, we have applied some basic algorithms for de-noising, segmentation, normalizing of characters, etc.

The present investigation focus on importance of application of Weibull distribution in reliability theory as it is frequently used based on the assumption of a special type of non-homogeneous Poisson process. Also discussed some of the important inferential statistics of Weibull process in application to reliability theory.
