“…Future studies will explore the potential for using the proposed TMA algorithm to improve the performance of various types of network, including wireless mesh networks (WMNs) [22][23][24] and vehicular ad hoc networks (VANETs) [25][26][27]. In addition, the effect of the wireless channel error on the video transmission quality should be considered into the proposed TMA algorithm for determining the AC queue mapping [2,7,15].…”

IEEE 802.11e utilizes the Enhanced Distributed Channel Access (EDCA) protocol to provide quality of service (QoS) support over WLANs. However, under EDCA, all video data are allocated to the same access category (AC) queue, irrespective of their coding importance. Consequently, the quality of the transmitted video may be severely degraded under heavy traffic load conditions. The literature contains several queue mapping mechanisms based on the settings of the AC queues, such as contention window size, for improving the video transmission quality over IEEE 802.11e WLANs. However, these mechanisms fail to consider the effect of the dequeuing time on the video delivery performance. Accordingly, the present study proposes a new queue mapping algorithm, designated as the throughput-based mapping algorithm (TMA), for improving the video transmission quality and reducing the video delay by dynamically allocating the video data packets to different AC queues based on their length and throughput such that the probability of the dequeuing time being reduced is increased. In implementing the proposed approach, the throughputs of the AC queues are analyzed using two Markov chain models. The simulation results show that TMA outperforms previously proposed static and dynamic queue mapping schemes in terms of a reduced AC queue length, an improved PSNR (peak signal-to-noise ratio), and a shorter transmission delay.

The traditional wireless network works in a single channel, and only one transmission path is generated by routing, which not only limits the network capacity and system throughput, but also easily generates collision conflicts when the traffic is large, and cannot provide good network performance. This paper optimizes the backbone MESH network from the perspective of multi-channel and multipath, and proposes an AOMDV routing protocol MM-AOMDV (Multi channel Multi metric AOMDV) based on multi-channel and multi-metric. Simulation results show that the MM-AOMDV protocol has better end-to-end delay, throughput and delivery rate network performance than the original protocol while the node density and traffic volume increasing.

“…The multi-path routing, which uses multiple diversity paths for data forwarding concurrently, is the best solution for improving communication e ciency and reducing the communication delay in WMN. The multi-path routing technique offer advantages such as resource maintenance, load balancing, bandwidth allocation, and fault tolerance [6] [7] over single path routing. Concurrent multi-path routing to the intended gateway through disjoint wireless routers reduces the impact of a link failure on communication.…”

With the ease of appending new nodes without re-installing the whole network, the Internet of Things (IoT) builds several smart applications on Wireless Mesh Network (WMN). One of the important aspects of integrating WMN and smart IoT applications is to provide an energy-e cient and reliable routing protocol. Seeking the communication route that delivers the high-quality stream quickly over WMN is an important issue, but the maximum utilization of a single high-quality path leads to poor throughput and large communication delay, including route discovery and data forwarding delay. The broadcasting mechanism creates redundant transmissions of control packets into the network and reinitializes the blind route discovery process due to link disconnections leading to network resource constraints and high delay during the route discovery process. Moreover, the congestion in the communication route incurs data transmission latency. This paper proposes the Multiple Disjoint Path Determination (MDPD) mechanism based on-demand routing in WMN to formulate the path discovery and data transmission latency. Reducing the neighbor list into the uncommon neighbor set reduces the unnecessary latency in route discovery, and deriving high capacity multiple disjoint communication routes reduce the communication delay in the proposed work. The proposed work employs the queue dynamics in queuing delay, which mainly provides adaptability to the dynamics in network capacity and e cient diversity paths to the gateway node to infer the available bandwidth and optimize the network tra c. To fully utilize the advantage of heterogeneous routers, it disables the ooding of control packets across the stable mesh routers, excluding the initial route discovery process, because it enables the available route storage system in each mesh router. Hence, the proposed work e ciently supports wireless broadband internet access with reduced delay and control overhead. The simulation results demonstrate the fast detection of the multiple disjoint routes and data tra c optimization over the discovered disjoint routes in the proposed MDPD mechanism over WMN.
