教学目的、要求
Wireless networks have gone through an unprecedented growth in the past few years, and will continue to play an indispensable role in future data communication. In the first part of the course, you will learn fundamentals in wireless networks ranging from physical layer to application layer. In the second part of the course, we will discuss research challenges and state-of-art approaches in Peer-to-Peer systems, service discovery in Wireless sensor/mesh networks. This class is a reading and project-based class examining and developing techniques for effective networking in the face of numerous challenges: high packet loss, frequent interruptions, mobility, high latency, and unpredictable conditions. Through class lectures, paper reading, and presentation, you will gain a broad understanding of the current technology and research efforts in wireless networking, as well as further developing skill for oral presentation and writing research critiques. In addition, students are expected to accomplish a well-defined research project in a group obtain experience in designing and evaluating protocols and/or techniques for wireless networks. This is a graduate course. So I expect you to be motivated, eager to learn, and willing to work hard to make up for any deficiencies you may have. After attending this course, I expect you to be able to: • Understand the main ideas behind some of the current innovations in networking including multimedia, p2p system and Wireless sensor/mesh networks • Become familiar with the current research topics in modern communication techniques.
