Towards Enabling Multihop Wireless Local Area Networks for Disaster Communications

Abstract

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.

Cooperative Communications Based on Deep Learning Using a Recurrent Neural Network in Wireless Communication Networks

“…To make things easier, relay selection was recommended construction of cooperative networks, motivated by the advantage of selection variety from multiuser selection and antenna selection. Te authors of reference [9] proposed a location-based technique for selecting the best relay based on geographical random forwarding notions [10]. Assuming that each node is aware of both its own and the destination's position, the relay is the node closest to the destination.…”

“…Several techniques for cooperative relay selection have been presented. Some of the major work is provided in reference [7], where the user pairing method based on orthogonally of the channel matrix is explored, and group-based user pairing is proposed in reference [9].…”

“…Te key parameters of wireless communication and networking are signal encoding and decoding techniques, spectrum limit, error detection and correction techniques, and architecture of the network. WCNs plays a major role in telecommunications and networking such as usage of cellular networks, wireless LANs, and diferent kinds of satellite services [5,9].…”

A Fuzzy-Logic Approach for Optimized and Cost-Effective Early Warning System for Tsunami Detection

“…In this approach, data are generated on the occurrence of an event. In our proposed model, the electromagnetic sensors are used at the point of the earthquake, and data are further hopped from these nodes towards gateway node using pressure sensors and aggregator sensors [23].…”

Smart Load-Based Resource Optimization Model to Enhance the Performance of Device-to-Device Communication in 5G-WPAN

“…When more memory management units (MMUs) are present in a system, performance benefits from partial offloading enabled by D2D are clearer, which indicates that the partial offloading models enabled by D2D are appropriate for the user-intensive scenarios. Existing partial offloading is affected by the constraints on communication resources, resulting in high latency [11]. Because helper computing resources are utilized during partial D2D-enabled offloading, latency in such systems can be kept at a low level, where the computing resources at the edge servers are sparse.…”
