“…With the application enhancement and the increase in QoS demand required the efficient and reasonable MAC protocol. Geng et al proposed the adaptive QoS MAC protocol with the transmission license concept. According to the load conditions, the number of transmission challenges was changed that controlled the nodes participation and channel sharing.…”

During the link failure conditions in Voice over Internet Protocol applications, the backup of routing information is an important requirement to offer the reliable data delivery to the destination. But the maintenance of multiple paths is the difficult and time consuming for the dynamic environment. But the hops reduction between the source and destination and the interference occurrence causes the transmission in multiple times and that leads to minimum network lifetime. Hence, the preservation of link between the multiple hops is the necessary task to improve the performance. This paper validates the link quality with the 4 measures as received signal strength indicator, bandwidth, node mobility, and the number of connections. The link quality factor (LQF) measurement considers the signal and noise level in 5 operating conditions to allow the automatic identification of closest neighbors and their location. The integration of tabu list and the heuristic-based fitness search algorithm constructs the routing path and updates the path to identify the link failure. The LQF estimation and the dynamic update provide an efficient data delivery path with less number of iterations. The comparative analysis between the proposed hybrid tabu-heuristic-based LQF with the existing protocols such as Adhoc On-Demand Vector (AODV), Optimized Link State Routing (OLSR), and the Interference-based Topology Control algorithm for Delay-constrained (ITCD) proves the effectiveness of tabu-heuristic-based LQF regarding the throughput, energy, packet delivery ratio with the minimum delay, and rebroadcasting probabilities.

“…We can see that nodes 0-1 have the lowest throughput, and nodes 6-7 have the highest throughput. This scenario is the result of the channel being continuously occupied by nodes (2, 3), (4,5), and (6,7). These nodes occupy the channel and block traffic (0-1), leading to unfairness among nodes.…”

SUMMARY The medium access control protocol determines system throughput in wireless mobile ad hoc networks following the ieee 802.11 standard. Under this standard, asynchronous data transmissions have a defined distributed coordination function that allows stations to contend for channel usage in a distributed manner via the carrier sensing multiple access with collision avoidance protocol. In distributed coordination function, a slotted binary exponential backoff (BEB) algorithm resolves collisions of packets transmitted simultaneously by different stations. The BEB algorithm prevents packet collisions during simultaneous access by randomizing moments at stations attempting to access the wireless channels. However, this randomization does not eliminate packet collisions entirely, leading to reduced system throughput and increased packet delay and drop. In addition, the BEB algorithm results in unfair channel access among stations. In this paper, we propose an enhanced binary exponential backoff algorithm to improve channel access fairness by adjusting the manner of increasing or decreasing the contention window based on the number of the successfully sent frames. We propose several configurations and use the NS2 simulator to analyze network performance. The enhanced binary exponential backoff algorithm improves channel access fairness, significantly increases network throughput capacity, and reduces packet delay and drop.

Ad-hoc wireless networks have gained much popularity due to their easy deployment and dynamic reconfiguration. Ad-hoc networks, as any other network need to support both real time traffic and normal data traffic. Multimedia applications demand stringent guarantees on bandwidth,delay and jitter. In a best effort network, all users obtain the same level of service which depends on the network load. In other words, it cannot support the sophisticated requirements of multimedia applications. Therefore, new mechanisms have to be developed to support the desired QoS(Quality of Service) levels for the modern applications.QoS provision at the medium access level is particularly important because it has direct effect on how and when data is transmitted.A lot of works have been reported that try to render the desired QoS to the application. Some of them are based on dividing traffic into various traffic classes and assigning different back off related values for each class. Some others are based on transmitting multiple frames at a time to reduce the number of contention attempts and some others discard frames with expired deadlines. But many of these dictate strict procedures for assuring the desired QoS of the application. The proposed method is a simpler one based on the application of token rings to wireless domain. It uses election algorithm to find who should transmit data next.Unlike token ring,the proposed system uses a distributed procedure for maintaining the logical structure of the ring.Experiments show that, with the proposed system, the response time of stations that need to send real time data is reduced.
