“…When there are 100 nodes, the system achieves a little over 300Mbps regardless of which scheme used. When using MCS level that achieves 54Mbps link speed and 1500 bytes of packet size, the actual throughput of a single node is approximately 30Mbps, due to the loss from PHY and MAC overhead [24]. With five channels, the effective total throughput is Wireless Communications and Mobile Computing approximately 150Mbps if a single node transmits on each channel.…”

As the density of wireless LANs increases, performance degradation caused by hidden terminals and exposed terminals becomes significant. These problems come from carrier sensing based medium access control used in current wireless LANs. Hidden terminals are created if carrier sense threshold is too high, whereas exposed terminals are created if carrier sense threshold is too low. A good threshold depends on how far nodes are placed from their destinations, but that cannot be controlled by the system. In this paper, we propose a simple scheme that makes use of multiple channels. Multiple channels could be utilized by equipping multiple radios or using advanced hardware such as SDR to divide a single channel into multiple channels. Nodes are assigned channels based on their estimated distance from the AP. Once the assignment is done, carrier sense threshold for the channel is selected so that as many concurrent transmissions take place as possible, while preventing hidden terminals. Simulation results show that the proposed mechanism achieves significantly higher throughput without causing starvation at the edge nodes.

“…When channel access is granted, the packet is transmitted from the interface. If a node has multiple network interfaces, we need a packet scheduler who maps packets to interfaces [6]. Each network interface has queues, so packets are assigned to interfaces before contending for the channel.…”

This paper presents a medium access control protocol for wireless networks that improves system spectral efficiency using multiple channels. Use of multiple narrow channels has already been proposed as a solution to reduce MAC overhead, but merely dividing a wide channel into narrow channels cannot mitigate the negative effect of packet collisions especially when the network is densely populated. The proposed protocol, called N-DCF, adds protocol support to reduce packet collisions and improve channel utilization. The main idea is to let each node contend on one of the multiple channels and give the node privilege to access other channels when it successfully finishes transmission on its contention channel. When a node gains privilege to a channel, it can access the channel without contention. Privilege is gained probabilistically so that other nodes can have chance to win the channel and obtain privilege for other channels as well. N-DCF reduces channel idle time by conducting random backoff only on one of the narrow channels and reduces packet collisions by assigning contention channel randomly. Idle channels are not wasted because nodes can access other channels once the node wins its contention channel. Performance evaluation shows that the proposed scheme achieves higher throughput than 802.11 DCF without harming the fairness, regardless of node density, packet size, and number of radios.

“…4) Other Technologies: LACP and MPPP are both examples of wired interface bonding. The Linux Bonding Driver [18] bonds together multiple network interfaces so they appear as a single aggregate resource to the kernel and upper protocol layers. The driver offers 7 different modes of transmission, including round robin, active-backup, 802.3ad, and broadcast.…”

“…These solutions were designed primarily for wired devices but can be used for wireless interfaces with severe performance limitations. So et al in [18] propose a module for the Linux Bonding Driver called New Load Balancing (NLB) designed specifically for wireless interfaces. The module measures the inter-arrival time of packets at the receiver using the packet-pair method and uses this to calculate the appropriate bonding schedule.…”

This work proposes a simple analytical model for interface bonding in 5G WLANs at the 2.4 GHz and 60 GHz ISM bands. Based on previous analysis of the IEEE 802.11 DCF by Bianchi and Chatzimisios, an expression for the predicted throughput of the bonded interface is given as a function of the number of competing wireless nodes in each network. The model is implemented and validated in MatLab using the Monte Carlo method. When applied to a practical interface bonding scenario, the model results suggest a practical limit of fifteen 2.4 GHz nodes when bonded with a 60 GHz interface, above which the resulting compound throughput is less than that of a single 60 GHz interface.
