xCalamities such as earthquakes and tsunami affect communication services by devastating the communication network and electrical infrastructure. Multihop relay networks can be deployed to restore the communication environment quickly in catastrophe-stricken areas. However, performance in terms of throughput is affected by deploying the relay networks. In wireless local area networks (WLANs), the primary purpose of multiband transmission employing multihop relay networks is to increase the throughput and reduce the latency. In the future, wireless networks are believed to carry high throughput, more data rates, and less latency by expanding bandwidth-demanding applications. Simultaneous multiband transmission in WLAN systems is considered to increase the coverage area without power escalation. Due to the inherent characteristics of different bands and channel conditions, transmission rates tend to be different. The impact of such conditions may cater to the disproportional distribution of data among bands, causing some of the bands to be overwhelmed, which incurs buffer overflow and packet loss. In contrast, the channel capacity of some of the bands remains underutilized. In this paper, we consider the channel conditions and transmission rates of each band on either side of the relay to address the problems mentioned above. Furthermore, this paper proposes a load distribution-based end-to-end traffic scheduling technique to improve system performance. The simulation results demonstrate the effectiveness of our proposed method with maximizing throughput and minimizing end-to-end delay.

“…To date, many researchers have considered the idea of multiband transmission in WLANs and cellular networks. Venkat et al [13] proposed a band switching mechanism in cellular networks. In the proposed architecture, when a primary node (a node responsible for switching the band) changes the band, all the secondary nodes (that are not allowed to switch the band unless instructed by the primary node to do so), change their bands accordingly.…”

Multi-hop relay networks are deployed to restore communication environment in the catastrophe stricken area. Deployment of these networks are fast and easy but performance is low due to the relay nature of the networks. Given the surge of bandwidth hungry application, performance such as high data rates, high throughput and ultra-low latency is a concern in traditional one-hop Wireless Local Area Networks (WLANs) as well. Simultaneous transmission over multiple bands is a compendious solution that has the potential to significantly boost data rates and flexibility. It will enhance the network utilization and performance of high-bandwidth applications effectively and efficiently. However, there are certain challenges that need to be addressed before taking full advantage of simultaneous transmission over multiple bands. In this work, we outline the factors affecting the performance such as throughput and end-to-end delay in multiband multi-hop WLANs. Considering these factors, we design an end-to-end traffic scheduling technique that minimizes end-to-end delay and maximizes throughput. We design a mixed integer linear program (MILP) that optimizes end-to-end delay and maximizes throughput. Illustrative numerical results show that proposed technique effectively minimizes end-to-end delay and maximizes throughput.

“…Venkataraman et al proposed a two‐hop multi‐band radio architecture for LTE‐advanced cellular networks, which enables the usage of CR technology in MCN with the help of several dedicated fixed cognitive gateways (CGs) within the cell. The CGs sense and utilize vacant primary channels for traffic relaying between BS and MSs in the outer region of the cell, while all CGs and MSs in the inner region of the cell communicate directly with the BS.…”

“…It is observed that none of the existing works proposed a multi‐interface CR mobile node model and explored its opportunistic spectrum utilization to enhance routing performance in MCN. This paper firstly presents the proposed model for the multi‐interface CR mobile node with an improved transceiver synchronization technique to address some of the key MAC and network layer issues discussed by Sengupta and Subbalakshmi and the limitations of the architecture proposed by Venkataraman et al . The opportunistic spectrum utilization of the proposed model is then investigated to enhance the routing performance in MCN.…”

Summary Multi‐hop cellular network (MCN) is a wireless communication architecture that combines the benefits of conventional single‐hop cellular networks and multi‐hop ad hoc relaying networks. The route selection in MCN depends on the availability of intermediate nodes and their neighborhood connectivity. Cognitive radio (CR) is an emerging communication paradigm that exploits the available radio frequencies opportunistically for the effective utilization of the radio frequency spectrum. The incorporation of CR and mobile ad hoc network routing protocols in MCN could potentially improve the spectrum utilization and the routing performance of MCN. This paper firstly presents the proposed model for the multi‐interface CR mobile node with transceiver synchronization and then investigates its opportunistic spectrum utilization and routing performance in MCN.
