Our physical world is transforming at an unprecedented rate into a complex and dynamic system of connected devices. Such dynamics are evident due to COVID-19 making the organisations rethink the way they work and operate. Working digitally and virtually across locations along with partner organisations is the need of the hour. Internet of Things makes such communication possible. The increasing importance of capturing real-time data and acting upon the insights is the driving focus of Internet of Things (IoT) – both in terms of its wider applicability and the path towards achieving scale. Defined as the interaction between the digital and physical worlds, IoT helps the digital world interact with the physical world using a plethora of sensors and actuators. The sensors take data from various devices, convert it into viable actions for human analysis. This paper brings forth Bluetooth, Zigbee, RFID, Z-Wave, Wi-Fi, ANT, 6LoRaWAN, NFC, GSM technology, and Cloud software technologies used by various IoT devices. They aid sensors which collect data from multiple devices. Comparison of these technologies is made on basis of frequency band, range, data rate and modulation type. This paper also discusses microcontrollers namely Arduino Uno, Adafruit Feather Huzzah32, SparkFun ESP8266 Thing, and Raspberry Pi which analyse, and process data based on various settings to perform tasks or provide the data required by industry. Wi-Fi technology embedded on Arduino controller is recommended, the deciding factors being security, availability, reliability, mobility, performance, scalability, interoperability, management and trust.
A low profile H slit monopole antenna with defected ground plane for WiMAX/WLAN applications has been presented in this paper. A single slit is cut initially followed by the anticlockwise rotated T slit, and finally a H-shaped slit cut in the patch provides the multiband resonance with enhanced impedance bandwidth. After the implementation of Defected Ground Structure in this low profile antenna, gain and radiation pattern is much better. The size of low profile antenna is 26× 32 × 0.8 mm3. The frequency range covered is (2.6-3.0 GHz)/2.8GHz, (3.6-4.7 GHz)/3.7 GHz and (5.4-5.9 GHz)/5.6GHz for WiMAX/WLAN applications. The impedance bandwidth of 14.28%, 29.72% and 8.92% have been achieved.
In this paper, the expressions for Average Symbol Error Rate (ASER) of Rectangular Quadrature Amplitude Modulation (RQAM) scheme have been investigated for an Arbitrary Equal Gain Combining (EGC) receiver with phase estimation error, over Nakagami-m fading channels. The response of the ASER for various levels of fading parameters m, the diversity order L of the receiver, and decision distance ratio have been observed. The phase estimation error of fading channels is considered for evaluation.
Digital signage is an emerging new communication technology. Digital signage system reduces the environmental costs associated with traditional printed signage. It is used to display the dynamic content (e.g., audio, video, announcements, webpages) using Internet of Things (IoT). It uses Raspberry pi a small credit card sized computer to store locally and process the information and also reduce the production cost. In order to update the information the content management software is developed using free open source software. The used programming technologies are WAMP server, Html Abstraction Markup Language (HAML), My structured Query Language (MySQL) database and Python. This proposed system is used to display the required information to the students in college campus and where the real time information is needed (e.g., Universities, Hospitals, Railway Station, Corporate buildings, malls, subways). Moreover the digital signage system is flexible and dynamic compared with printable signage system.
Now-a-days, secured information transfer to others require security because the data might be stolen from hackers. To avoid these type of problems, are use Cryptography Secure Algorithms. Cryptography Algorithms play important role in network security. It is an Advanced Encryption Standard (AES) Algorithm. The AES is a Symmetric encryption using private key. This encryption process consists of blocks such as Key Expansion, Pre Round Operation, Add Round Key, Sub Bytes, Shift Rows and Mix Column. The Advanced encryption standard algorithm is using cryptographic secret keys-128 bits, 192 bits, and 256 bits to encryption, and decryption input data is 128 bits. This paper represents the survey of Cryptography Secure AES algorithm.
