Data communication techniques

Smart car deals with the smart collision avoidance between the vehicles using visible light communication. The basic concept behind this technique is that the data can be transferred through LED light by varying light intensities faster than the human eyes can perceive.

Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

Used to communicate IP status and error messages between hosts and routers Uses IP to route its messages between hosts Must be implemented with IP remember, IP is just a packet delivery system transmits and routes datagrams from sources to destinations through a series of interconnected networks it has a checksum in the IP header to detect lost bits no error detection on the datagram payload though but has no native mechanism for source host notification This is where ICMP comes in its used to report IP errors to the source host ICMP data is carried as the payload of an IP datagram specifie...

Frame Relay For datatransfer, X.25-based packet switching has established itself worldwide as a standard and very reliable means. However, X.25 is not a technique suited to the higher quality and speeds of so by modern data communications networks, and it is beginning to be supplanted new techniques, among them ‘frame relay’. In this chapter we start by discussing the shortcomings of X.25-based packet switching in carrying highspeed bitrates and explain how frame relay was designed to overcome these problems....
