Project-1: Designing and Implementing of TCP/IP protocol Stack

Description: Project main objective is to design and implement a high performance TCP/IP

protocol stack in C. One goal is to make design and implementation maintainable.Another goal is to make the protocol stack comparative in speed than other existing protocol stacks. The resulting protocol stack implements the IP, ARP, and UDP protocols from TCP/IP protocol suite. It also deals with SNMP, OSPF, BGP and routing techniques. To evaluate its performance we devised two ways of measurement. The first compared the round-trip time for a packet sent between two hosts and the other is to measure the time spent in the stack.

Project-2: Image compression

Description: Image compression is concerned in minimizing the number of bits required to represent an image. As digital image is an array of real numbers represented by a finite number of bits. The image is first digitized and stored as a matrix of binary digits in computer memory. The information is transformed in number of frames per sec and it is compressed as it is and the coming frame is predicted from it. The difference between actual and predicted one i.e., error is DCT transformed and then coded. Thus the error is compressed but not the entire frame.

Role and Responsibility: Programmer in developing software and also took lead in analyzing. Software Development using C. Installation, Integration, Debugging and Demonstration of the system.

Environment: C, WinXP, Jpeg standards.
