Abstract

The requirement for a secure emergency communication system has become imperative in tandem with the industrial revolution. Additionally, the development of technology has led to increasingly robust penetration techniques that pose a threat to communication system security, leaving data vulnerable to unwanted third parties. This paper introduces a novel, powerful security approach that ensures a secure emergency communication system. Moreover, this research focuses on several cryptographic techniques among various symmetric and asymmetric ciphers, including advanced encryption standards, substitution, and transposition. The article presents an affordable and secure communication system that can transmit data over long distances with low power consumption using long-range technology. This system features a unique function that transmits updated locations, directing rescuers to the designated location.

Abstract

In this paper, a novel optimal two-way amplify and forward (AF) differential beamforming method for wireless sensor network is proposed. The proposed method is an advanced signal processing technique used to enhance the performance and reliability of the communication link by exploiting the diversity provided by multiple antennas. Unlike current state-of-the-art methods which require the knowledge of channel state information (CSI) at both transmitting and receiving antennas or at least at the receiving antennas, the suggested method does not need CSI at any transmitting or receiving antenna. Moreover, the proposed method enjoys high error performance with high diversity and coding gain and has a very low encoding and decoding complexity. Through our simulations, the proposed method is proved to outperform the best known non-coherent multi-antenna methods.

Abstract

Neglecting one's health is a major contributor to the decline in overall well-being, often resulting in the onset of various diseases and health issues. The avoidance of such complications becomes feasible with the introduction of a device capable of monitoring heart pulses at regular intervals, ideally every 60 seconds. The main goal of this article is to design a healthcare system that ensures continuous monitoring of heart activity and temperature, functioning as a proactive tool to keep individuals informed about their physiological parameters. This involves the incorporation of a heart rate sensor and temperature sensor in a wearable device, essentially serving as a first aid tool. The heart rate is measured by detecting pulses and calculating beats per minute, utilizing an appropriate heart monitoring sensor tailored to the specific needs of the individual. The main concept revolves around designing a wearable device that harnesses the capabilities of the digital age, making use of features such as wireless sensors and rapid data transfer through the internet of things, accessible on various smart devices. The device focuses on detecting and monitoring heart rate and temperature, with the sent data being relayed to the healthcare provider. The doctor can then monitor the patient's status through the displayed data on thing-speak.

Abstract

This study focuses on developing an efficient and cost-effective approach for compressing Phonocardiogram (PCG) signals without compromising their quality. The method utilizes two data compression techniques, capturing heart sounds and transforming them into the frequency domain to extract essential features such as frequency, phase, and amplitude peaks. The compressed signals are subsequently reconstructed to faithfully replicate the original heart sounds. The findings contribute to advancements in biomedical signal processing and compression methodologies, with potential applications in telemedicine and remote sustainable healthcare systems. Compressed PCG signals enable real-time remote consultations and continuous cardiac health monitoring, particularly in underserved regions with limited medical resources. This research holds significant potential for improving access to cardiovascular healthcare and promoting overall health and well-being.
