Internet has become a part of our daily life. Most of the communications or the transfer of the data which is happening is over the internet. With Internet of things the devices can transmit data with each other over the internet. As there is internet involved, the security of the data also becomes important. Confidentiality is important in the healthcare sector where encryption plays an important part. There are many encryption algorithms already
present which are effective, through this work we are proposing a novel method that aims at adding the randomness to the encryption algorithm. The random number generation technique used in this paper is Web Scraping, here the data is scraped from the web page
where the data gets constantly updated which adds to the randomness. The random number generation module is added to the existing encryption algorithm and the encryption algorithm is tested on different file sizes to test the level of encryption.

Dr. N. Rakesh and Adwani, K., “Smart City Traffic Control System”, in International Conference on Intelligent Communication Technologies and Virtual Mobile Networks (ICICV 2019), Francis Xavier Engineering College, Tirunelveli, India, 2019.[Abstract]


Traffic light control systems are widely used to control the flow of the traffic. Due to rapid increase and continuous flow of the vehicles there is a lot of traffic congestion and people tend to break the traffic rules risking their life. Pedestrians are meant for the people to cross the road who are on foot but the vehicles are there on the pedestrians. At times breaking the traffic rule might lead to accidents. At night street lights are on even though the street is empty, which is a waste of energy and is a serious issue. So as to reduce the traffic congestion and make the people follow the traffic rules we propose “Smart City Traffic Control System”. It consists of a dynamic traffic light control system (based upon the density), a laptop camera (for monitoring and it will record the video in case if traffic rule has been broken, this recording will be stored and mailed to the traffic police department), a GSM module (to notify the traffic police department via SMS that a traffic rule has been broken, TSOP sensor, Arduino Mega Microcontroller, LEDs.

P., “A Novel based Decision tree for Content Based Image Retrieval: An Optimal Classification Approach”, in 7th International Conference on Communication and Signal Processing, Adhiparasakthi Engineering College Melmaruvathur,Chennai, India, 2018.[Abstract]


In this 21 st century, the development of multimedia technology is at its peak. Content based image retrieval (CBIR) is an Inventive methodology which can retrieve images based on consequently inferred highlights, for example, color, texture, features and surface of an object. The application of this technology spread's from medical science to national security including a vast variety of fields. In this system the main challenge is image indexing and similarity ranking for the proper retrieval. A solution to this problem is introducing a Firefly optimization combined Decision Tree (FF-DT) classifier to reduce the computational complexity in the classification stage of feature extraction. Precision rate and recall rate are the evaluation matrices used to evaluate the efficiency of this work. The result obtained from the experiment proves that the proposed approach is more efficient in CBIR system than the existing methods.

Developing cost-effective solutions to deliver broadband connection to undeserved or under-connected communities using fixed wireless access technology can be achieved by canopy networks. The former can be implemented using MIMO-OFDM technique. The implementations of MIMO-OFDM in systems have shown promising results in terms of system performance improvement. This paper presents high-speed FFT algorithms for wireless personal area network (WPAN) applications which uses high data rate. In WPAN, the FFT/IFFT block plays the major role. To eliminate the huge burden of the computational requirement of the FFT/IFFT process, the divide and conquer algorithm is employed here. This method not only improves the efficiency but is also easy to implement. In this work, the concept of Discrete Fourier Transform is discussed and the same is implemented using MATLAB for the MIMO-OFDM process.

The heterogeneous networks are those which can connect different devices running with different operating systems and using different protocols. The main problem with these networks is network connectivity. In order to ensure the continuous network connectivity between the nodes, the Delay Tolerant Networks (DTNs) are useful as they operate on extreme distances and depend up on the changing positions of the nodes. The Epidemic Routing Protocol (ERP) makes use of DTN concept. The previous works show the performance of Epidemic Routing Protocol in terms of packet delivery ratio, end-to-end delay, and energy consumption. In this work, the Epidemic Routing Protocol's performance for Delay Tolerant Networks will be evaluated by considering different parameters like, Average Latency, Energy Balancing Factor, and Number of Alive and Dead nodes.

With the advancement in sensing technology, applications are moving from wired to wireless region. The main challenge is the energy consumption of individual sensing nodes. When first node dies system becomes unstable and we cannot make use of the untapped node's energy. There comes the relevance of TSEP like protocols in such heterogeneous network. Heterogeneous in the sense with respect to node energy the system becomes unstable. This work analyzes the advantages of TSEP like protocols. When we are manufacturing application for predicting the environmental pollution, natural and ecological disasters, all need to be communicated at present. So energy of sensing node places a crucial factor. The primary source of a sensor node is usually a battery and is usually neglected once it is deployed, which creates routing decision problem and scalability issues. In this work, the data acquisition happens by using a temperature sensor application, the proposed work captures data and it is analyzed using stable election protocol by observing the output performance with respect to lifetime of sensing nodes.

In recent days the Worldwide Interoperability of Microwave Access (Wimax) technology has become popular and receives acceptance as a broadband wireless access (BWA) system [5]. Wimax communication, which enables transmission of voice and data wireless in urban and highway environments [5]. In this study we considered, Wimax frequency 2.6 GHz and 3.5 GHz in urban and highway for RSS terrains [2]. RSS(Receiving Signal Strength) to measure the power between base station(BS) and mobile station(MS)[8]. RSS becomes efficient coverage, when base station proximity near to mobile station [8]. RSS deteriorates, when mobile station moves far from base station. Variation in signal strength from transmitter(Tx) and receiver antenna (Rx) would be considered as path loss [8]. In our work, the analysis is done using MAT Lab simulation software. With different path loss models, considering urban and highway terrains with RSS for given WiMax frequency in SIMO (Single Input Multiple Output) channel[5]. We have proposed ECC model is better since this model supports frequency greater than 3.0 GHz [2].

Radio propagation in wireless communications varies based on the speed of frequency operation, mobile terminal and the parameters like, transmitter antenna height, mobile height, connector loss, cable loss, antenna gain, path losses and receiver sensitivity. The Path loss and the parameters of the transmitter (TX) and receiver (RX) depend on the received signal strength. The establishment of the quality of call is based on received signal strength. Signal strength varies based on different terrains. In this paper, Cost-Hata model, ECC-33 model and Ericsson models are considered for Path loss calculation [2]. The different receiver antenna heights (1.5m and 10m) of signal strength is calculated and compared with proposed propagation models for different terrains.

To fulfill the end-users demand for access to the Internet “anywhere-anytime” and ensure quality of service, is the WiMAX (Worldwide Interoperability for Microwave Access) technology standardized based on IEEE 802.16 that provides efficient packet radio interface enabling transmission of high data rates. WiMAX network became popular and receives growing acceptance as a Broadband Wireless Access (BWA) system which is the solution of “last mile” wireless broadband. WiMAX has potential success and is gaining hike all over the world for deployment of the network in its line-of-sight (LOS) and non-line-of-sight (NLOS) conditions for both fixed operation below 11GHz and Mobile operation below 6 GHz frequency range. In the first step of cell planning and deployment of wireless network, estimation of path loss is very important in turn to get better signal strength to access Internet. In this work, we have used well-structured propagation models for analysis and comparison at different terrain areas, the models are - COST231 Hata model, COST231 Walfisch-Ikegami model, ECC-33 model, Ericsson model, and SUI model for SIMO (Single-input Multiple-output) channels. Using environmental parameters and some correction factors path loss is calculated for all terrain (urban, suburban, and rural) conditions. This provides guidelines for cell planning of mobile WiMAX at cellular frequency between 2-6 GHz.

Technology keeps evolving every second. Humans receive all the essential information with just one touch. Be it the weather forecast or ordering any grocery or communicating with one's peers, everything happens so easily and efficiently. It is undoubtedly user friendly. When the same technology associates itself with the medical equipment it becomes easier to fetch and process the patient's data in real time. It also helps to make several life-saving, spontaneous decisions for the critical care. This paper talks about the patient monitoring system. The physiological parameters of the patient are continuously monitored in real time using sensors. The data that is obtained from the sensor is then sent to an Arduino Uno microcontroller where it is analyzed. If the patient's data differs from the required threshold values, an emergency message is sent to the assigned doctor's mobile. This is done using the GSM module which is interfaced with the microcontroller. Verifying the system in software is done using Proteus.
