“…Figure 4 shows the saturated throughput of the IEEE 802.11 MAC protocol in the simulator, which has a similar trend to the results of (Figure 6) in [48] and in this simulation. Figure 5 shows the normalized throughput for SA-MMAC, AMMAC, BiMMAC, and IEEE 802.11 in the developed simulator to compare against (Figure 4) in [47]. As both the figures match the trend in results of the original works, we are confident this simulation produces the correct results with high precision.…”

Medium access control (MAC) protocols in ad hoc networks have evolved from single-channel independent transmission mechanisms to multi-channel concurrent mechanisms to efficiently manage the demands placed on modern networks. The primary aim of this study is to compare the performance of popular multi-channel MAC (MMAC) protocols under saturated network traffic conditions and propose improvements to the protocols under these conditions. A novel, dynamically adaptive MMAC protocol was devised to take advantage of the performance capabilities of the evaluated protocols in changing wireless ad hoc network conditions. A simulation of the familiar MAC protocols was developed based on a validated simulation of the IEEE 802.11 standard. Further, the behaviors and performances of these protocols are compared against the proposed MMAC protocols with a varying number of ad hoc stations and concurrent wireless channels in terms of throughput, Jain’s fairness index, and channel access delay. The results show that the proposed MMAC protocol, labeled E-SA-MMAC, outperforms the existing protocols in throughput by up to 11.9% under a constrained number of channels and in channel access delays by up to 18.3%. It can be asserted from these observations that the proposed approach provides performance benefits against its peers under saturated traffic conditions and other factors, such as the number of available wireless channels, and is suitable for dynamic ad hoc network deployments.

“…Devendiran et al introduced an asynchronous multichannel MAC (SA‐MMAC) protocol that enables the transmission of concurrent wireless over noninterfering channels and MAC protocols increase the network performance. Here, IEEE 802.11 MAC cannot use the features completely and support only high‐performance applications.…”

A major challenge to the mobile ad hoc network (MANET) is the ability to efficiently utilize the available capacity. The exposed terminal problem (ETP) and the hidden terminal problem (HTP) are considered as major concerns in the media access control (MAC) layers of MANET. During transmission, there is an increase in energy consumption, unnecessary delay, overhead, and the number of retransmission due to the request to send (RTS) packet collision. To eliminate these problems, we have developed an algorithm called receiver collision sensing scheme in multiple access control (RCSS‐MAC) for collisions detection by the receiver. This method uses appeal for RTS (ARTS) packet to detect unsuccessful RTS packet. Here, we use only the minimal number of ARTS to reduce unnecessary retransmission, delay, and RTS collision. The performance of this method can be improved using the contention window (CW) management scheme to reset and renovate the failed system. In RCSS‐MAC, an additional field (victory rate) in MAC frame is utilized to control the CW management to reflect the network condition in and around the receiver. Simulation is carried out under the open‐source second version of the network simulator (NS2). As a result, RCSS‐MAC algorithm achieves better performance than conventional techniques in terms of delay, throughput, and energy consumption and network lifetime.

“…Hybrid CCC improves network throughput, reduces power consumption and eliminate the collisions because of hidden terminals. For maximizing the network enforcement and authorizing the non-wired transmission simultaneously through interfering less channels, authors in [16] develop an asynchronous multi-channel MAC protocol. However, wireless fidelity (Wi-Fi) protocol does not support all features.…”

Efficient channel utilization is the utmost challenge in mobile ad hoc network (MANET). Moreover, Medium Access Control (MAC) layer in MANETs experiences hidden and exposed terminal issues. During data transmission, there occurs increased energy consumption, overhead and many retransmissions because of the collision of Request To Send (RTS) packet. In order to solve this problem, we propose an algorithm named Fore-handed Collision Avoidance MAC (FCA-MAC). This protocol mainly focuses on the collisions detected at the destination. In FCA-MAC, the failed RTS packet detection is considered with Appeal for Request To Send (ARTS) packet. To reduce the delay, RTS collision and redundant re-transfer, we consider the minimum number of ARTS packets. To regulate the Contention Window (CW), an additional field factor named triumph factor is introduced in FCA-MAC which reflects the complete network state at the destination. Implementation of FCA-MAC is done using Network Simulator (NS2). Results reveal that the proposed FCA-MAC outperforms standard techniques with regard to various performance metrics.
