“…Many efficient multicast routing algorithms have been proposed in the MCMR WMNs related literature: [9][10][11][12][13][14][15][16][17][18][19][20][21], to name a few. Most of these algorithms assume that the multicast group is static, while in reality, the group is highly dynamic and its size can greatly change over time as members are allowed to join or leave the group at any time.…”

“…There are significant proposals for CA protocols and their metrics are mainly classified as interference-aware, traffic-aware, congestion-aware, and delay, etc. [ 35 ]. Another viewpoint is from the operating layer: MAC layer alone, coordinated MAC and upper layers (i.e., cross layer), and their integrated approach (defined as common layer) [ 36 ].…”

Round Robin based Intermittent Periodic Transmit (RR-IPT) has been proposed which achieves highly efficient multi-hop relays in multi-hop wireless backhaul networks (MWBN) where relay nodes are 2-dimensionally deployed. This paper newly investigates multi-channel packet scheduling and forwarding scheme for RR-IPT. Downlink traffic is forwarded by RR-IPT via one of the channels, while uplink traffic and part of downlink are accommodated in the other channel. By comparing IPT and carrier sense multiple access with collision avoidance (CSMA/CA) for uplink/downlink packet forwarding channel, IPT is more effective in reducing packet loss rate whereas CSMA/CA is better in terms of system throughput and packet delay improvement.

“…The channel assignment approaches in MR-WMNs are surveyed in many works in the literature such as [24][25][26][27][28] and the joint approaches of channel assignment and routing are surveyed in [29][30][31]. The joint configuration of channels and routes in MR-MC WMNs in the literature such as [6,13] are mainly based on centralized load-aware solutions where configuration of routes and channels are obtained for a given distribution of traffic load demands across the network.…”

Joint channel assignment and routing is a well-known problem in multi-radio wireless mesh networks for which optimal configurations is required to optimize the overall throughput and fairness. However, other objectives need to be considered in order to provide a high quality service to network users when it deployed with high traffic dynamic. In this paper, we propose a re-configuration optimization model that optimizes the network throughput in addition to reducing the disruption to the mesh clients' traffic due to the re-configuration process. In this multi-objective optimization model, four objective functions are proposed to be minimized namely maximum link-channel utilization, network average contention, channel re-assignment cost, and rerouting cost. The latter two objectives focus on reducing the re-configuration overhead. This is to reduce the amount of disrupted traffic due to the channel switching and path rerouting resulted from applying the new configuration. In order to adapt to traffic dynamics in the network which might be caused by many factors i.e. users' mobility, a centralized heuristic re-configuration algorithm called State-Aware Joint Routing and Channel Assignment (SA-JRCA) is proposed in this research based on our re-configuration model. The proposed algorithm reassigns channels to radios and re-configures flows' routes with aim of achieving a tradeoff between maximizing the network throughput and minimizing the re-configuration overhead. The ns-2 simulator is used as simulation tool and various metrics are evaluated. These metrics include channel-link utilization, channel re-assignment cost, rerouting cost, throughput, and delay. Simulation results show the good performance of SA-JRCA in term of packet delivery ratio, aggregated throughput and re-configuration overhead. It also shows higher stability to the
