Security remains as one of the most important aspects of smart cities. At present, due to the increased population and urbanization there is a huge demand for smart security system. But, existing CCTV and IP cameras are inefficient interms of image quality and these systems require large amount of storage space.…

Water is the main resource for Agriculture and still, most of the farmers are using traditional methods of irrigation for farming and a large amount of water is getting wasted due to these methods. These outdated techniques have to be replaced with automated techniques. In this paper, we proposed a new irrigation system, which works based on the latest IoT technology to reduce the wastage of water and it reduces manual labor to irrigate the crops.…

Surveillance is the one major thing that anyone wants and required to protect their things or monitor their places. In this paper, we proposed a movable surveillance camera using Raspberry Pi and Webcam. The movement of the proposed surveillance camera can be controlled by using the designed web browser and python scripting language. It can cover a wide area. The proposed architecture is portable and movable.…

Energy-saving techniques play a key role, as there is a huge demand for electricity in the present situation due to increased population, urbanization and industrialization. Hence, energy monitoring techniques are becoming more prominent. Therefore, a considerable amount of research work is in progress for energy conservation. By using the Internet of Things, we can save energy to a great extent..…

Existing water grid and water quality monitoring systems are manually operating and low-efficiency systems. Water leakage and contamination cannot be identified in existing systems. We proposed an Internet of Things (IoT) based Water monitoring system to monitor quality of water, leakages, contamination, and to manage pipeline networks. Generally, water flow starts from an administrator tank (Water head tank) through a pipeline…

In recent times, there have been many floods due to heavy rainfall the overflowing of water from rivers and dams was increasing concern in India. The purpose of this project is to investigate the occurrence of rain and to predict the floods in advance using an electronic node (3 ultrasonic sensors and a microcontroller) to collect the water level at regular time intervals in addition to this node, there will be a temperature and humidity sensors to collect values from surrounding nature at a catchment area.…

This paper addresses the calculation of noise power for the OFDM system using repeated nulled subcarriers. Most of the methods, which are already in use are calculated the noise power in the frequency domain by assuming perfect Carrier Frequency Offset(CFO). Hence, it leads to degradation of performance. In this paper, we proposed a time-domain periodic nulled subcarrier based method for estimating the noise power by assuming the existence of CFO..…

Traffic congestion is the most common problem in the majority of the countries around the world due to increased population and urbanization. Traffic blockage is mainly due to the increased number of vehicles, poor infrastructure, and failure of existing systems. There are several techniques to identify the congestion of traffic such as image processing, laser tracking, and inductive loop..…

As per the records of world blindness and visual impairment, globally there are millions of blind people, facing several problems in leading an independent life. The aim of the proposed model is to design and develop an intelligent voice-based guidance system using various ML and DL algorithms and to enhance their lifestyle through our smart solution. The proposed prototype consists of five (05) unique functional blocks in which each block assists the user in performing the corresponding task through voice commands from the headset.…
