The number of mobile phone users today is growing dramatically, which will cause network jamming and require a substantial amount of bandwidth. Cloud radio access network (C-RAN) is thus one of the interesting technology alternatives to solve this issue. C-RAN communicates with users using dispersed Remote Radio Heads (RRHs), each of which has one baseband unit (BBU). RRH performs soft relaying and is connected to the BBU via high capability, low latency front-haul lines. Due to the exchange of raw I/Q samples between the RRHs and the BBU, the C-RAN architecture places a restriction on front-haulfront-haul bandwidth. In BBU, many methods, including joint decompression and decoding (JDD) and wyner-ziv coding, are utilised to increase capacity.

We have created an electrotherapy system that will optimize the properties of tissue heating using a natural philosophy circuit that creates a high voltage at a frequency of 0.3–a pair of MHz. Applications in medicine uses these qualities. In order to improve tissue heating, a high voltage pulse signal with a peak voltage of almost 2 kV is used in this paper's investigation of a high frequency electrotherapy system. In terms of frequency and voltage, this optimum tissue heating between the inner tissue and the thermal distributions has been investigated. One conductor serves as the target tissue heater in an experiment that was specifically designed to identify the tissue heating properties. In the end, a technique to substitute electrotherapy that is appropriate for a specific tissue depth is devised.

The main goal of this project is to design and construct a low-cost wheelchair control system that uses an Android phone. Patients with diverse physical limitations have relied on wheelchairs to assist them with movement and to meet their day-to-day prerequisites. However, in other circumstances, the mobility of a wheelchair is dependent on another person. It includes people who are unable to lift their arms or push the wheels forward, such as paraplegics, quadriplegics, stroke patients, the elderly, and others. Joystick-oriented wheelchairs, which are supposed to be a solution for these people, might cause a variety of issues since they demand fundamental shoulder mobility. For the categories described above of patients, this is not always practicable. Furthermore, because it is wireless and can be worn on either hand, this solution does not have the positioning restrictions that a joystick wheelchair could have, allowing the user to sit in their preferred posture for the least amount of pain. The goal of this initiative is to enable autonomous mobility for people with disabilities. Thus, this research study provides a Bluetooth-based wheelchair prototype that maybe operated by an Android smartphone application. A transmitter and a receiver that can communicate wirelessly makeup the framework. The 433 Mhz RF Transmitter and Receiver Unit was utilized for wireless transmission since it delivers data through an antenna at speeds ranging from 1Kbps to 10Kbps and has a range of up to 100 metres, The wheelchair's receiver unit receives signals from the transmitter unit through an Arduino Uno micro-controller, which causes the wheels to turn in the desired direction. Motor drivers that convert electricity as needed by the wheels makeupmakeup the reception unit. This technology offers an alternative to commercial wheelchairs since it is more effective, less expensive, and simpler to control.

Due to the availability of technology and basic necessities, smart cities are now increasingly populated. In order to inspect, monitor, and signal the availability of parking spaces or slots in crowded regions, we presented a smart parking system that entails the deployment of an IOT module on-site. This project combines IOT with a coordinated framework for an effective and simple method of parking the auto-mobiles without having to look for open spaces. The main intention of this Smart Parking system is to comprise the IOT module which is utilized for signaling the driver of vehicle and mainly its condition of accessibility of single parking spot or place. The project also includes a perspective on the engineering of the framework from an abnormal state. At its conclusion, the project analyses the framework's operation in the form of a usage case that supports the viability of the suggested show. The Arduino Uno and Ultrasonic Range Detection Sensor are used to visually identify the vacant slots. Vehicle drivers can locate the open spot in the parking lot by measuring the distance using ultrasonic sensors. It can reduce the amount of time spent seeking and make it very easy for the driver to find the spot. As soon as a parking space in the parking lot is discovered to be unoccupied, ultrasonic sensors are used to identify it, which results in a further report. Programming the Arduino Uno, sensors, and other components enabled us to accomplish this. The main foremost inspiration of this idea is to minimize the clog of vehicles in urban areas effectively. In the daily newspapers, we have seen many articles with respect to the vehicles stopping issues and parking place issues all over India and mainly in the cities like Delhi, Mumbai, Chennai, Bangalore and numerous metropolitan urban areas. In a recent study, many researchers have found that for one year, the vehicles like cars and bikes are consuming approximately 186823. 5 liters of fuel and releasing almost 825 tons of carbon dioxide. Everyone is responsible for this so, the aimless driving should come to an end in the parking areas where this project is highly suitable to save the nature and parking problems all over the world.

Wellbeing related issues and boundaries are of most extreme critical to man and are fundamental for his reality. The correspondence between submerged and land is a profoundly difficult one. Radio transmissions that movement through air pass on quickly in water. Acoustic or sonar, sent by submerged gadgets, generally bounces off the surface while never getting through. This causes failures and different issues for an assortment of uses, for example, sea investigation and submarine-to-plane correspondence. This paper presents a framework for giving constant distant well-being checking of an individual's condition with upgrades of an SMS alert through Global System for Mobile correspondence (GSM). This task focuses on the plan and execution of a minimal expense; however, proficient and adaptable individuals observe and ready framework involving Global System for Mobile correspondence (GSM) innovation. In this venture heartbeat and temperature of the body are estimated by sensors and performs hindrance recognition utilizing IR, which conveys the messages to the Control unit and showcases on Liquid Crystal Display (LCD), and cautions through bell when he is in peril utilizing crisis switch.

The importance of Digital Signal method (DSP) algorithms has increased drastically in recent times, the two very important techniques of DSP unit the Distinct Fourier rework (DFT) and thus the fast Fourier rework (FFT). DFT is mostly utilized within the applications sort of convolution, a linear filtering etc. Another algorithmic rule to reason DFT efficiently is that the fast Fourier remodels (FFT). Fast Fourier rework processor incorporates a vital role inside the sphere of communication system like audio broadcasting and digital video etc.

Energy efficiency is a key problem in Wireless Sensor networks because of the limited energy capacity of sensor nodes. There have been several works towards reducing energy consumption during the transfer of the packet to the base station and several clustering-based protocols have been found to improve network lifetime. In this research paper, a novel technique to reduce energy consumption has been proposed. The algorithm has been implemented using MATLAB and compared to existing LEACH and SEP protocol. The results obtained in terms of the number of dead nodes, several alive nodes, and throughput and packets transferred show the efficiency of the proposed protocol over the other two protocols.
