- Abstract:

Aiming at the delay-sensitive applications with an unbalanced property of network flow, a new protocol called the parallel two-level polling control based MAC (PTLP-MAC) is proposed in this paper. The PTLP-MAC provides priority distinction from the aspects of the polling route and service scheme assignment. By proceeding with the data transmission and request parallel, the mean waiting time of the data packet is further reduced. Furthermore, by use of the embedded Markov chain and the theory of probability generating function, the mathematical functions were established and closed form expressions were given for obtaining the mean cyclic period, as well as the mean queue length and the mean waiting time characteristics. The analytical results were also verified through extensive computer simulations.
