“…In [7], the channel assignment in both Omi-directional and directional antenna are covered. Besides these surveys, some works review the existing channel assignment based on joint channel assignment with routing [9] and topology control [10]. Our paper differs from the previous works in three aspects.…”

“…Both of the aforementioned assumptions are difficult to hold in the distributed environment or may require considerable cost. The channel assignment schemes have broadly been classified in terms of static, dynamic, and hybrid . Static scheme is the simplest in nature where channels once allocated are fixed and fairness is provided in terms of other quality parameters, which have relatively rigid thresholds.…”

With the introduction of service-centric applications, the provision of quality of service (QoS) would be a challenge in both classical as well as IoT Networks. 1 The value can be added by monitoring these networks in priority areas and spontaneously levelling the traffic, so that network congestion could be avoided. 2,3 Wireless Mesh Networks (WMNs) are gaining in attraction for metropolitan operations as well as being considered successful for IoT communication. Typically, a wireless mesh network is composed of access points, called Mesh Routers (MRs), which interwork hops to hop to form a larger backhaul network.However, these MRs perform additional functionalities as compared to traditional routers, eg, self-healing. The MRs are usually statically placed and of fixed transmission power in contrast to the classical routers used in ad-hoc networks, which typically vary. Hence, in WMNs', interference can be more controlled. [4][5][6][7][8][9] Similarly, MRs in WMN can have multiple radios and thus interference estimation should be based on all radios, which does not usually pose a difficulty in ad hoc networks as routers are equipped with only a single radio. 10 Hence, a comparatively better performance and throughput can be achieved in WMN against ad-hoc networks. However, MRs equipped with multiple radios can also experience some complexities as parallel transmissions in close proximity cannot occur on the same channel at the same time. Assigning each radio, a different channel is practically not possible as this may result in logical disconnection of the network topology. 11There are 3 non-overlapping channels in IEEE 802.11b that are least interfered eg, channels 1, 6, and 11. [12][13][14][15] Besides the fact that the number of available channels is usually less than the number of radios in proximity, this paper discusses the problem of assigning a limited number of Concurrency Computat Pract Exper. 2020;32:e5650.wileyonlinelibrary.com/journal/cpe

“…Due to the presence of multiple interfaces on each mesh router multiple channels form IEEE 802.11b can be assigned to mesh node. This strategy improves the network throughput up to a great extent [4]. In case of single-radiosingle channel (SRSC) design each mesh node has only one radio and that radio can use only one frequency channel.…”

Multi-radio multi-channel wireless mesh networks (MRMC-WMNs) in recent years are considered as the prioritized choice for users due to its low cost and reliability. MRMC-WMNs is recently been deployed widely across the world but still these kinds of networks face interference problems among WMN links. One of the well-known interference issue is information asymmetry (IA). In case of information asymmetry interference the source mesh nodes of different mesh links cannot sense each other before transmitting data on the same frequency channel. This non-coordination leads to data collision and packet loss of data flow and hence degrades the network capacity. To maximize the MRMC-WMN capacity and minimize IA interference, various schemes for optimal channel assignment have been proposed already. In this research a novel and near-optimal channel assignment model called Information Asymmetry Minimization (IAM) model is proposed based on integer linear programming. The proposed IAM model optimally assigns orthogonal or non-overlapping channels from IEEE 802.11b technology to various MRMC-WMN links. Through extensive simulations we show that our proposed model gives 28.31% network aggregate network capacity improvement over the existing channel assignment model.
