Telemetrie Body Area Network (TBAN) system is one of the useful methods to realize improving user's body behavior and monitoring health condition. Not only showing physical parameters, by feedback of vital information to user, TBAN system is extended to the autonomous system closed to user. Getting such information, user is able to improve his body behavior consciously. Moreover, telemetric function...
In most water distribution systems, an appreciable volume of water is lost through leaking pipes, resulting in financial loss and environmental pollution among others. Thus, water loss constitutes a major challenge to utilities around the world. As water pressure is one of the causes of pipe burst resulting into leakages, pressure control could reduce the possibilities of pipe bursts. Thus, water...
Wireless Sensors Networks (WSNs) have been gaining significant attention in both the industries and the academia in recent years. However, WSN are vulnerable to growing security threats and attacks which are inept for the current traditional security mechanisms to cope with or mitigate such security challenges. As a solution, Software Defined Network (SDN) has emerged and been merged with WSN to form...
RF Voltage transformers operating in one of the ISM frequency bands have recently been demanded in emerging low-power applications, such as wake-up radios in wireless networks, remotely triggered switches, stand-by units in home electronics, etc. S0 Lamb wave resonant (LWR) transformers have been first proposed. Later, SAW transformers designed as “degenerated” CRF have been proposed. Here we demonstrate...
In last few decades, as a result of the advances in microelectromechanical systems, Wireless Sensor Networks (WSNs) have gained a considerable attention due to their low-cost, low-power and small-scale sensor nodes which are used to integrate sensing, processing, communicating capabilities to solve many different real world problems. The placement of sensor nodes is a very important step to cover...
VANET and cognitive radio network (CRN) are both new emerging technologies in wireless networking. The application of CR concept in wireless communication systems for intelligent vehicles has been envisioned as a promising idea towards solving the problem of scarce spectrum. This paper discusses CR technologies for VANETs aimed at opportunistic spectrum access (OSA) for improved vehicular communication...
Our daily life is characterized by countless human relationships. Every day we go to work, do shopping, partake in leisure time. At the base, there are some choices that lead us to make a series of activities; In which we interact and relate with many people. What influences the choices we make? Answering this question can be a very daunting task. However, it can help us to identify the main key elements...
The advances in wireless low-power sensors and the increasing demand for portable healthcare monitoring systems have inspired the realization of Wireless Body Sensor Networks (WBSNs). IEEE Std. 802.15.6 defines the communication protocol for WBSN applications in terms of physical and medium access layers. The high generality and flexibility of standard requirements poses the question of how WBSN parameters,...
Climate change and resultant scarcity of water are becoming major challenges for countries around the world. With the advent of Wireless Sensor Networks (WSN) in the last decade and a relatively new concept of Internet of Things (IoT), embedded systems developers are now working on designing control and automation systems that are lower in cost and more sustainable than the existing telemetry systems...
