TCP - Asymetric links (DSL), Satellite, ..

Recall that TCP makes assumptions regarding the forward and reverse paths. For networks such as Cable, DSL, satellite broadband networks, such assumptions do not hold. We investigate how such changes affect TCP performance.

TCP - Wireless

Recall that TCP makes assumptions regarding the forward and reverse paths. We investigate how the characteristics of wireless networks affect TCP performance.

Wireless Ad Hoc Networks - Routing

Wireless ad hoc networks promise flexible deployment without the need for deployed infrastructure (wireless base stations). In this lecture, we will survey some of the popular wireless ad hoc routing protocols for the IEEE 802.11 standard wireless LAN networks.

Wireless Networks - Energy considerations

Next we look at energy consumption issues with wireless networks.

Security - Viruses/Worms/DOS/DDOS/..

Continuing with our discussion on wireless network security, we look at security and denial of service issues in the larger Internet.
