Networking and Mobile Computing

Various internetworking concepts including the Internet, Wireless LAN, Mobile ad hoc and sensor networks, distributed and high performance cluster computing, and peer to peer networks. We study how the layers of the protocol stack and the different functional aspects of a network system are affected by mobility.
