The most challenging issues in the multi-channel MAC of the IEEE 1609.4 standard is how to handle the dynamic vehicular traffic condition with a high mobility, dynamic topology, and a trajectory change. Therefore, dynamic channel coordination schemes between CCH and SCH are required to provide the proper bandwidth for CCH/SCH intervals and to improve the quality of service (QoS). In this paper, we use a Markov model to optimize the interval based on the dynamic vehicular traffic condition with high mobility nodes in the multi-channel MAC of the IEEE 1609.4 standard. We evaluate the performance of the three-dimensional Markov chain based on the Poisson distribution for the node distribution and velocity. We also evaluate the additive white Gaussian noise (AWGN) effect for the multi-channel MAC coordination scheme of the IEEE 1609.4 standard. The result of simulation proves that the performance of the dynamic channel coordination scheme is affected by the high node mobility and the AWGN. In this research, we evaluate the model analytically for the average delay on CCHs and SCHs and also the saturated throughput on SCHs.

“…The authors assumed a non-ideal transmission channel, and considered the immediate freezing of backoff time, when the channel is busy. In [5], the authors produced a 3D-MCM, to estimate the transmission rate in the optional reservation mechanism, under conditions of a non-ideal transmission channel, and considered the effect of Bit Error Rate (BER > 10 −5 ) on different types of frames. The model [5] is based on two main counters: station minimum attempt number for the RTS/CTS and station maximum attempt number for DATA/ACK frames.…”

“…The proposed protocol improves the ST, effectively reduces the average time to access the channel, and in order to derive an optimal CW. The work [12] proposed a new 2D-MCM, to analyze the ST of the IEEE 802.11 DCF protocol in the presence of hidden nodes, and in an ideal transmission In the models described in [2], [5], [6], [7], [9], [13], [15], when a station wants to transmit data, decrements the selected backoff successively, without taking into account that the transmission channel is occupied by another station (the transition probability that the channel is occupied p busy = 0). When backoff time becomes zero, the station starts transmitting the packet, with success or failure.…”

In this paper, we focus on the study of the Distributed Coordination Function (DCF) protocol, which is based on the basic CSMA/CA multiple access scheme, provided with a second RTS/CTS mechanism to avoid collision effects. However, the major problem that causes the loss of frames is the internal or external signals' influences, which disturb the transmitted signal, and thus noise errors occur. This leads us to suggest a new analysis of the Saturation Throughput (ST) for IEEE 802.11b DCF protocol. We consider the Packet Fragmentation Mechanism (PFM), Data Fragment Retransmission, without Renewing the Channel Reservation Mechanism (DFR/RCRM) and the distinction between control frames lost due to noise and control frames lost due to collisions. This work provides an analytical model of 3D Markov chain. It is closer to the real IEEE 802.11b DCF protocol's functioning and calculates the ST in a very precise manner. We determined the appropriate ST for both cases where the DFR/RCRM was and was not employed. The results indicate that a wireless network installed in a noisy environment utilizing DFR/RCRM performs better than one using a simple IEEE 802.11b DCF.

To improve the performance of RTS/CTS scheme in error-prone WLAN channel, this paper proposes an enhanced scheme utilizing Back-to-back DATA Retransmission and packet loss differentiation. With this new scheme, the packet which encounters transmission error can be retransmitted continuously without additional backoff time and RTS/CTS handshake. The system performance of this enhanced scheme is evaluated by a three dimensional Markov chain model. The numerical results show that this new scheme can improve the saturation throughout and reduce packet delay in error-prone channel.
