A reconfigurable antenna built on E-shaped structure with an ability to control bandwidth is discussed in this proposed work. To configure antenna automatic or manual tuning is done so that they can accustom to the varying system requirements thus can avoid those limitation and offers extra functionality. A frequency reconfigurable E-shaped patch antenna can be utilized for improving the bandwidth.The bandwidth can cover the frequency range from 1.85 GHz-2.33 GHz. The enactments of the offered antenna, in terms of reflection losses and radiation patterns, with divergent DC bias voltages is analyzed using a varactor diode. A broad research was taken over to analyze the nature of the antenna at different frequency.Keywords

Zigbee protocol is used to send the packet from source to destination. It does not have any routing table and route discovery method. Tree topology method followed by ZigBee Tree Routing (ZTR). But it will not be provided the best routing path from source to destination. Shortcut Tree Routing (STR) can be used to provide best optimal path. STR will calculate the hop count from source to destination with help of Zigbee protocol. Zigbee protocol having the hierarchical addressing format. Shortcut Tree Routing method does not have security procedure option. Because of this our technique will be protected in safe manner. Most of the sensor networks are having self centered node. Due this there is a possible to get performance degradation between source and destination. These selfish node should be identified to get make better formance for sensor networks. Main theme of our paper is to find selfish node from the networks and providing best route between source to destination. Our aim is to get efficient data delivery using Watchdog method.Keywords

Objectives: To design and produce the loop antenna in order to identify or measure the brain stroke detection between the applicable frequency range of 300 MHz to 3 GHz, during in a usual and unusual conditions. A design terminology for embedded antennas has been imitated on the malleable or flexible substrate which is based on the process of Electro Cartography (ECOG). Methods/Statistical Analysis: The brain stroke detection techniques are analyzed through the Real time network link interfaces between the human brain and automated cosmetic surgery, that can implement the illusion of many inmates anguishing or suffering from depression, anesthetic cord or spinal cord injury, stroke, and alternatively damaging neurological breast implants in order to use cosmetic surgery appendage in the equivalent manner as organic limbs. This is managed with some related appliances that transmit the formation or attention into the movement of Brain Machine Interface (BMI) systems. Findings: The loop antenna generally uses the frequency range of up to 3GHz and based on this limited frequency, only the fixed frequency is mainly applicable for this concept around 400 MHz. During normal conditions and in abnormal conditions, the frequency range is acceptable within the range of 300 MHz to 3 GHz. For a fixed value of frequency it commonly provides low directivity and coefficient based on permittivity and conductivity. Here, the antenna is usually designed for a maximal link gain networks beyond the human scalp to effectively increase the embed power. A simulation result of this loop antenna implies that enhancing the communication or transmission frequency together along with an antenna calculation can provide absolute power and voltage signal to the required embedded antennas. Application/Improvements: This is mainly applicable for cosmetic surgery limbs, where such systems desire neurological sensors for neural reporting and brain incentive, and also it provides an improvement in a path to a peripheral unit that figure out the neural link data and restricts the imitation actuators.Keywords

Portable Internet that has the gigantic prevalence, or, in other words benefits in an anchored way that, has turned into a perilous issue. Physical layer security (PHY-security) has been perceived in a successful way that way to upgrade the remote security by making utilization of remote medium qualities, e.g., commotion, blurring and impedance.
An especially entrancing PHY-security innovation is an agreeable transfer which is because of the way that it conveys dispersed assorted variety and abbreviate the entrance remove. This procedure offers an answer in the path on different multi receiving wire transferring innovations to enhance the physical layer security. These exploration results on multi-reception apparatus hand-off supported PHY-security and also a portion of the privacy execution improvement plans. Specifically, the emphasis is on the substantial scale MIMO (LS-MIMO) transferring innovation, or, in other words to tackle the different testing issues for actualizing the remote PHY-security, for example, short separation block attempt without meddler channel state data (CSI) and with defective real CSI. In addition, the future bearings are perceived for further improvement of mystery execution.

A recurrence reconfigurable space ring receiving wire exchanging among L and C groups is exhibited. Opening of a L-band space ring reception apparatus can be reconfigured to a 2x2 C-band opening ring receiving wire exhibit by changing the conditions of 16 PIN diode switches. This receiving wire works at 1.76/5.71 GHz in L/C band working states separately. The deliberate acknowledged addition and radiation effectiveness are 0.1/4.2dB. Estimated results demonstrate that the PIN diode switches make them load impacts on the receiving wire. Parametric investigation of each circuit component is likewise reenacted and given in this paper. programming utilized is HFSS for reproduction. The proposed receiving wire is intended to emanate and transmit measure up to measures of intensity. The arrival loss of the proposed reception apparatus is higher than that ideal for oneport receiving wire application at the ideal double band frequencies.Keywords

Ultrasound is the best imaging techniques for detection of abnormalities in the human body. Ultrasound is a medical imaging technique in which a transducer transmits and receives the ultrasound waves to and from the organs of the human body. Ultrasound waves are high-frequency wave ranges from 20 KHz to Giga Hertz. Ultrasound methods are non-invasive, pain-free and patient-friendly techniques. Detection of abnormalities using Ultrasound helps doctors to treat the patient. Abnormalities in liver, Breast, Kidney, Uterus, Heart, Liver, Nerves, Prostate found out using ultrasound techniques has a list of unidentifiable problems in Medical Images in traditional methods. Deep learning plays a vital role in the modern era for much problem identification in medical imaging and other domain.Keywords
