1. Title: "Design and Implementation of a Low-Power Wireless Sensor Network for Structural Health Monitoring"

Abstract: Wireless sensor networks (WSNs) have emerged as a promising tool for structural health monitoring. In this paper, we present the design and implementation of a low-power WSN for structural health monitoring. The network consists of a number of sensor nodes, which are deployed on a structure to monitor its health. The nodes are equipped with sensors to measure various parameters such as temperature, strain, and vibration. The data collected by the nodes is transmitted wirelessly to a base station, where it is processed and analyzed. The proposed WSN is designed to be low-power, which enables it to operate for extended periods of time without the need for frequent battery replacements. The effectiveness of the proposed WSN is demonstrated through a series of experiments conducted on a steel beam.

2. Title: "Performance Analysis of Visible Light Communication Systems for Indoor Applications"

Abstract: Visible light communication (VLC) has emerged as a promising technology for indoor communication. In this paper, we present a performance analysis of VLC systems for indoor applications. We consider various aspects of the system such as modulation scheme, transmission distance, and receiver sensitivity. The performance of the VLC system is evaluated in terms of bit error rate (BER) and throughput. The results show that VLC systems can achieve high data rates and low error rates for short-range communication. However, the performance degrades rapidly with increasing distance. We also discuss various techniques to improve the performance of VLC systems, such as channel equalization and error correction coding.

3. Title: "Design and Implementation of a Software-Defined Radio Platform for Cognitive Radio Applications"

Abstract: Cognitive radio (CR) has emerged as a promising technology for efficient spectrum utilization. In this paper, we present the design and implementation of a software-defined radio (SDR) platform for CR applications. The SDR platform allows for flexible and dynamic configuration of the radio parameters, which enables efficient spectrum sensing and allocation. The platform is implemented using the USRP software-defined radio platform and GNU Radio software. The effectiveness of the proposed SDR platform is demonstrated through a series of experiments conducted in a real-world environment. The results show that the proposed platform can effectively sense and allocate the available spectrum, thereby improving the spectrum utilization efficiency
