Syllabus
Chapter 1: Introduction
This chapter motivates the field of wireless networks, covers some related history, followed by
challenges that explain why wireless protocol design is difficult.
Chapter 2: Physical Layer
This chapter deals with the challenges related to converting bits to signals. It starts with various
modulation techniques, followed by antenna fundamentals. It then digs into the various channel models
that capture how signals get distorted in air and then covers solutions that help recover back bits from
distorted signals.
Chapter 3: Link Layer
This chapter covers various topics related to link layer: Framing, Error Control, Media Access Control (MAC).
Two case-studies involving current technologies 802.11 and Cellular are also covered.
Chapter 4: Network Layer
Mobility is essential to handle as part of wireless networks. The chapter covers network layer solutions to
handle mobility (specifically Mobile IP) and also ad-hoc/mesh routing protocols like DSDV, OLSR, DSR.
Chapter 5: Transport Layer
This chapter discusses the various implications of wireless media on current transport layer protocols and
then covers solutions that can improve their performance.
