This article proposes a hybrid algorithm for spectrum allocation in cognitive radio networks based on the algorithms Analytical Hierarchical Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to improve the performance of the spectrum mobility of secondary users in cognitive radio networks. To calculate the level of performance of the proposed algorithm...

The development of health tele monitoring through wireless body area networks (WBANs) is an evolving direction in personalized medicine and home-based mobile health care. In a health tele monitoring system, a WBAN consists of a number of lightweight miniature sensors. The sensors measure physiological parameters such as electrocardiography (ECG), electroencephalogram (EEG), body temperature, an...

Potentially large number of cryptography solutions to attain security is widely known and recognized. Looking for a stronger scheme is the aim of most researchers to hide valuable information from each other. In this information age, many encryption algorithm exist to help keep information secure and these algorithms vary in complexity and ability to resist cracking. In this paper we present a ...

Considering smartphone-based indoor localization and tracking, combination of Wi-Fi fingerprinting pedestrian dead reckoning (PDR) becomes prevalent due to wide deployment access points easily inertial measurement units (IMUs) on smartphones. Since depends the similarities between online offline received signal strengths, it suffers from fluctuation radio measurements. Meanwhile, PDR relies IMU...
