A Novel Chaos-Based Cryptographic Scrambling Technique to Secure Medical Images

These days, a tremendous quantity of digital visual data is sent over many networks and stored in many different formats. This visual information is usually very confidential and financially rewarding. Maintaining safe transmission of data is crucial, as is the use of approaches to offer security features like privacy, integrity, or authentication that are tailored to certain types of data. Protecting sensitive medical images stored in electronic health records is the focus of this article, which proposes a technique of encryption and decryption. In order to safe-guard image-based programs, encryption methods are applied. Privacy, integrity, and authenticity are only few of the security elements investigated by the proposed system, which encrypts medical pictures using chaos maps. In all stages of the protocol, the suggested chaos-based data scrambling method is employed to mitigate the short-comings of traditional confusion and diffusion designs. Bifurcation charts, Lyapunov exponents, tests for mean squared error and peak-to-average signal-to-noise ratio, and histogram analysis are only some of the tools we use to investigate the suggested system's chaotic behavior.

An Automated Power Conservation System (APCS) using Particle Photon and Smartphone

Nowadays, people use electricity in all aspects of their lives so that electricity consumption increases gradually. There can be wastage of electricity due to various reasons, such as human negligence, daylighting, etc. Hence, conservation of energy is the need of the day. This paper deals with the fabrication of an "Automated Power Conservation System (APCS)" that has multiple benefits like saving on power consumption there by saving on electricity bills of the organization, eliminating human involvement and manpower which is often required to manually toggle the lights and electrical devices on/off, and last but most importantly conserve the precious natural resources by reducing electrical energy consumption. Two IR sensors are used in this project and these two sensors are used for detecting the presence of a person in the classroom. When the existence of the person is detected by the APCS it automatically turns on the fans and lights in that classroom and during the absence they will be automatically turned off, thus paving the easiest way to conserve power. This hardware is integrated with the Android app, where the user can get data on his smartphone regarding the number of fans and lights that are turned on at a particular instance of time. The user can also switch on/off the fans and lights from anywhere in the world by using the Android App.

Impact of Mobility on Power Consumption in RPL

The main theme of this paper is to implement the mobility model in Cooja simulator and to investigate the impact of the mobility on the performance of Routing Protocol over Low power Lossy networks (RPL) in the IoT environment. In the real world, mobility occurs frequently. Therefore in this paper, a frequently used mobility model -- Random Way Point (RWP) is used for analysis. RWP can be readily applied to many existing applications. By default, the Cooja simulator does not support mobility models. For this, the Bonn Motion is introduced into Cooja as a plugin. As IoT deals with the resource-constrained environment, a comparison is done between the static environment and the mobile environment in terms of power consumption. As expected, the results indicate that mobility affects the RPL in terms of Power Consumption.

Performance Evaluation of Advanced Congestion Control Mechanisms for COAP

In Internet of Things (IoT), the simple IPv6 capable electronic devices with limited hardware resources like memory and power resources are called constrained devices. Congestion is a major issue in network communications of these devices. To solve congestion in networks of constrained devices, Internet Engineering Task Force (IETF) had designed Constrained Application Protocol (CoAP). CoAP deals congestion with a basic Congestion Control (CC) mechanism called Default CoAP. Afterward, CoCoA and CoCoA+, an Internet-draft-recommendations, has been introduced as the elective CC mechanisms for CoAP. However, limited evaluations had done on these CC mechanisms of CoAP. In this paper, the performance evaluation of Default CoAP, CoCoA, and CoCoA+ Congestion control mechanisms are evaluated through Simulations in different network topologies and varied in different Link Delivery Ratios (LDR) of sensor nodes in constant traffic scenario by using Cooja Simulator. The simulation results are generated and CoCoA+ shows a better performance in constant traffic scenario comparing to Default CoAP and CoCoA.

Identification of the Most Significant Parameter for Optimizing the Performance of RPL Routing Protocol in IoT Using Taguchi Design of Experiments

Internet of Things (IoT) consists of a wide variety of devices with limited power sources. Due to the adhered reason, energy consumption is considered as one of the major challenges in the IoT environment. In this research article, an attempt is made to optimize the existing Routing Protocol (RPL) towards a green technology. It focuses on finding the most significant parameter in the RPL using Taguchi Design of Experiments. It emphasizes the effects of five input factors, such as Network Size, Mobility Speed, DIO_DOUBLING, DIO_MIN_INTERVAL, and Redundancy Constant on only one output parameter Power Consumption. The findings show that DIO_MIN_INTERVAL is the leading factor that has a significant effect on the power consumption in RPL. After determining the most significant factor that affects the power consumption, measures can be taken to optimize the performance of RPL by applying some optimization techniques. COOJA simulator is used to carry out the simulations required for this research article.
