In this tutorial, we are going to learn about the Carrier Sense Multiple Access (CSMA) – which is a better version that Aloha discussed earlier.

In subject area: Computer Science Frequency Division Multiple Access (FDMA) is a scheme used to provide multiple access in which different users are separated by assigning them different carrier frequencies. In FDMA, signals from various users are assigned different frequencies, allowing for isolation ...
The protocol is based on Time Division Multiple Access, in which the communication channel is divided into time frames, which are further subdivided into time slots. Each network node (ship) is assigned a particular slot, with exactly one slot for each node. With HAMA each node is allowed ...
The ALOHA System Research project began in September 1968, with the purpose of defining [ 2 ] "those situations where radio communications are preferable to conventional wire communications." The properties of the wireless medium led to the use of a new form of random access channel architecture,...
Code Division Multiple Access (CDMA) is a method that allows multiple sources of data to be transmitted over a single RF carrier by using unique pseudo-random noise (PRN) codes for each source, ensuring mutual orthogonality and excellent performance in the presence of interference and reflections....
During the last decades, multiple access technique has been widely used in mobile communications and provided increasable capability and various services, i.e., from traditional voice to multimedia communications, as shown in Fig.1. It plays a fundamental and important role in cellular networks. ...
