Wireless Networking Concepts: WMAN, WiMAX, and IoT Analysis

This homework assignment provides a detailed exploration of wireless networking concepts. It begins by defining frequency reuse and channel reuse, explaining their significance in wireless local area networks (WLANs) and how they help mitigate interference. The assignment then delves into Wireless Metropolitan Area Networks (WMANs) and WiMAX technology, discussing their functionalities and the challenges associated with WiMAX, such as security threats like man-in-the-middle attacks and denial-of-service (DoS) attacks, as well as issues in the physical layer like scrambling and jamming. Furthermore, the assignment analyzes the Internet of Things (IoT) and ZigBee technology, examining key issues like connectivity, security, and energy management within the IoT context. It also discusses the design and simulation of ZigBee transmitters, including the MAC and physical layers, and the use of Direct Sequence Spread Spectrum (DSSS) to avoid interference. The assignment concludes with a comprehensive list of references.
