Abstract
In real-time communication such as multimedia and videoconferencing, there is delay in transmitted messages The Objective of the thesis is to study and execute the protocol Virtual-Time Carrier Sensed Multiple Access (VTCSMA) which is used to minimize the missing transmitted messages. In this thesis we study Multimedia operating system, Real-Time Operating System, Communications in Real –time and we use (C++) program to execute the code that is established to the VTCSMA algorithm and then we study the rate of the real time clock to the virtual time clock and observe the results for the various values of the rate. We see that when the rate increase the missing messages decrease and the results are identical to the results obtained mathematically. We conclude that the protocol (VTCSMA) is minimizing the missing transmitted messages.
