With the availability of inexpensive devices like storage and data sensors, collecting and storing data is now simpler than ever. Biotechnology, pharmacy, business, online marketing websites, Twitter, Facebook, and blogs are some of the sources of the data. Understanding the data is crucial today as every business activity from private to public, from hospitals to mega mart benefits from this. However, due to the explosive vo Read More

Background: There is a task of autonomous determination of the position latitude of unmoved vehicles. Also, there is another task of the initial value latitude determination as a prepared operation of gimbaled and strap-down inertial navigation systems. For both cases, it is necessary to have an inertial measurement unit (IMU) with triad gyroscopes and triad accelerometers. The output signals of micromechanical gyrosc Read More

Background: In this article, an approach to harvesting electrical energy from a mechanically excited piezoelectric element has been described. Three PMN-xPT compositions were used with x taking the values of 0.31, 0.33, and 0.35 in order to study the most important properties of piezoelectric PMN-PT in energy harvesting. Objectives: This study uses a detailed analysis of three Relaxer (1-x)PMN-xPT ceramic compo Read More

Aim: For a Wireless Sensor Network (WSN), the sensor node deployment is a critical issue since it reflects the coverage quality. It is the most fundamental issue in WSNs, and it has a great effect on the overall WSN application performance. When it is necessary to deploy randomly sensor nodes in a field of interest to form a WSN, ensuring a high coverage quality becomes difficult. In the random deployment scenario, the Read More

Background: In free space optics (FSO) communication system, turbulence in the atmosphere leads to the intensity fluctuations of the received signal at the receiver end. Due to this reason, the performance of the free space optical communication system gets affected and results in fading of the received signal. Objectives: Performance improvement of FSO system using sophisticated channel modelling and fading mitigatio Read More

Aims: This paper presents agent-based localization using the mobile sink in wireless sensor networks. This proposed scheme is less expensive than GPS. It has a longer lifetime and is more energy-efficient. The mobile sink has a large and easily replenishable energy reserve and is movable within the sensor network's deployment area. Objective: In this work, a mobile sink is proposed that traverses inside the network's boundary a Read More

Background and Objective: The core problem of wireless body area network (WBAN) nodes is their limited energy resource. Thus, an energy-efficient routing protocol is crucial to this type of network. A major drawback of current routing protocols is that they do not consider the monitoring of a large number of patients, which may be problematic in the event of disasters. In addition, most routing algorithms fail to Read More
