Why are wireless networks different? • Here are a few reasons • open communication medium • radio signals spread through the environment in contrast with wired communications • user mobility – changing topology • lack of centralized control • mobile users are easily compromised • cooperative/distributed algorithms and protocols
• Protocols developed for wired networks often do not apply to wireless • • • • Page 10
Unreliable and Unpredictable Wireless Coverage - vary over time and space Open Wireless Medium – Interference, Hidden Node, Exposed Nodes, Security Mobility - poor-quality wireless links, intermittent connection, changes context Portability - Limited battery power, Limited processing, display and storage Fall 2012

Wireless Networked Systems Course • The course is roughly divided into three parts: 1. Introduction to the basic 802.11 mechanisms (medium access, rate adaptation, power save mode) covering both the legacy 802.11a/b/g MAC protocols as well as the most recent 802.11n MIMO standard. 2. State-of-the-art in Enterprise and home wireless networking discussing several challenge topics such as load balancing, channel management, node deployments, centralized networks, network management, measurements and evaluation. 3. Recent advances in wireless networking, such as cognitive radio networks, white space networking, advanced MAC protocol design, PHY-MAC cross-layer interactions, and wireless data centers.

Course Workload • Class presentations and open discussions ➤ Each student will be required to present 2-3 papers in the entire semester
• Survey/Research paper ➤ Each student prepares a survey/research paper on an interesting topic to you (suggested list will be provided by me)
• Research term-project implementation ➤ In groups of 2 (max 3).
• Maybe: 1 mid term, No Final Exam ➤ Tentative date of mid-term: Mid march after Spring break
