Evaluation of Correlation-Based Data Aggregation Approaches in Sensor Networks: Effectiveness and Challenges | Chapter 8 | Research Updates in Mathematics and Computer Science Vol. 4

Data aggregation represents a fundamental process within wireless sensor networks, facilitating the transmission of environmental data to end-users via base stations. Despite its critical role, data aggregation often receives less attention compared to routing and energy optimization challenges. This work presents a comprehensive review of existing data aggregation schemes, with a specific emphasis on correlational-based approaches. Our analysis reveals a significant gap in research dedicated to correlational-based data aggregation techniques. Furthermore, existing methods tend to overlook crucial factors such as data quality, computational complexity, and appropriate benchmarking. Addressing these unresolved issues is essential for enhancing the reliability and quality of data aggregation processes in wireless sensor networks. This chapter outlines the key challenges and opportunities for future investigations in this domain.

Secure Automated In-home Patient Monitoring | Chapter 14 | Highlights on Medicine and Medical Research Vol. 12

 Early detection and prevention of diseases rely heavily on in-home patient monitoring. The construction of a wireless sensor network to monitor a patient in his or her home is presented in this study. Various body sensors are attached to the patient's body in order to collect data such as temperature, blood pressure, ECG, and pulse rate. Most monitoring systems currently employ a personal computer (PC) as a local database to store patient body parameters prior to transferring them to the hospital. In this case, a cell phone replaces the requirement for a computer. The body parameters recorded by sensors are kept private and sent to the hospital in a secure manner. To accomplish security, a variant of Ciphertext Policy Attribute-Based Encryption (CP-ABE) with a double encryption approach is utilised. Because the patient always has his or her phone with them when they leave the house, outside monitoring is also enabled by the mobile phone. As a result, the mobile phone serves as a local database, obviating the need for a computer and allowing for outdoor surveillance. Finally, a temperature sensor is used to implement real-time monitoring. A temperature sensor, an analogue to digital converter (ADC), a microcontroller, an LCD, and a Bluetooth device make up the sensing circuit.
