Anti-Jamming Using Frequency Hopping

Abstract

This project report presents a MATLAB-based simulation that examines the impact of WLAN interference on Bluetooth communication and evaluates the effectiveness of Adaptive Frequency Hopping (AFH) as an anti-jamming technique. Bluetooth, a popular wireless technology for device connectivity, faces challenges due to interference from WLAN networks, which can affect its performance and user experience. To address this issue, AFH selectively avoids channels prone to WLAN interference. The simulation focuses on analyzing the performance of the Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) Physical Layer (PHY) when exposed to WLAN interference, comparing scenarios with and without AFH implementation. By assessing real-world scenarios involving WLAN interference, the simulation aims to demonstrate how AFH dynamically allocates Bluetooth packet transmission and reception to channels with lower interference. This dynamic allocation enhances the reliability and quality of Bluetooth communication, mitigating the effects of WLAN interference. The project report highlights the efficacy of AFH in improving Bluetooth communication under WLAN interference conditions, offering insights into its potential application in practical anti-jamming scenarios. Through the MATLAB simulation, the report provides a comprehensive analysis of AFH's impact on Bluetooth performance, emphasizing its role in enhancing the reliability and quality of wireless communication.
