Course Significance and Rationale Mobile networks are gaining importance Different type of mobile networks deployed Will be oriented more toward IP connectivity and data transport

Widespread use of mobile devices and networks, diffused in our daily life, is a reality Its beneficial to understand it

Its fun to play with protocols (software) Designing architecture to fulfill mobility req.

Course Objectives Explain the design and performance of wireless networks, protocols, and applications Along with the constraints of wireless technologies

Explain the operation of wireless LAN/MAN/PAN Explain routing schemes for mobile host connectivity Explain application-level features needed for mobility Develop (or use) simulation software using mobility at IP layer Understand the impact of hardware on protocols

Course Objectives At the end of this course, you should be able to: Identify the problems that arise in mobile networked environment Explain advantages/disadvantages of existing solutions to the problems in different mobile networking scenarios Evaluate novel approaches to these problems Identify and describe the purpose of each component of a mobile networking protocol Understand the implications of a given solution for performance in mobile networking environments

Pre Requisites Required: Thorough understanding of computer networks Good knowledge of TCP/IP protocol suite It will be required!

Good knowledge of C language

Recommended: C Programming experience in Linux environment
