Optimization computer network and bluetooth technology for parallel analysis of data transmission in programming

Technological problems and transmit data can be given a solution using Bluetooth technology. Bluetooth technology is used to transmit data over a distance of about 15 m. This data transmission analysis aims to apply and implement damping on the glass wall using a bluetooth device, in sending data files to replace the function of the data cable. So with this problem, a room that is partitioned using glass walls is designed and built. The hypotheses made: The material barrier factor between the master and slave greatly affects the attenuation of the received signal. In addition to the above factors, attenuation is also influenced by the distance between the master and slave. With two glass skate partitions and the distance between the master and slave will affect the data transfer speed. This study is to determine the attenuation of the double glass wall between the user and the server on the LAN network, using 15 PCs that are placed in a glass-insulated room on the same floor. The Bluetooth used is class 2 with a power of 2.5 m watts with a range of 15 m. The result of this research trial is that attenuation in a room with a glass wall in the room produces power losses, only experienced by the signal between the master and slave, the farther the distance the signal attenuation is, the greater the power losses, which results in more the amount of reduction in transfer rate from master to slave.

Detection of Management-Frames-Based Denial-of-Service Attack in Wireless LAN Network Using Artificial Neural Network

Wireless Local Area Networks (WLANs) have become an increasingly popular mode of communication and networking, with a wide range of applications in various fields. However, the increasing popularity of WLANs has also led to an increase in security threats, including denial of service (DoS) attacks. In this study, management-frames-based DoS attacks, in which the attacker floods the network with management frames, are particularly concerning as they can cause widespread disruptions in the network. Attacks known as denial of service (DoS) can target wireless LANs. None of the wireless security mechanisms in use today contemplate defence against them. At the MAC layer, there are multiple vulnerabilities that can be exploited to launch DoS attacks. This paper focuses on designing and developing an artificial neural network (NN) scheme for detecting management-frames-based DoS attacks. The proposed scheme aims to effectively detect fake de-authentication/disassociation frames and improve network performance by avoiding communication interruption caused by such attacks. The proposed NN scheme leverages machine learning techniques to analyse patterns and features in the management frames exchanged between wireless devices. By training the NN, the system can learn to accurately detect potential DoS attacks. This approach offers a more sophisticated and effective solution to the problem of DoS attacks in wireless LANs and has the potential to significantly enhance the security and reliability of these networks. According to the experimental results, the proposed technique exhibits higher effectiveness in detection compared to existing methods, as evidenced by a significantly increased true positive rate and a decreased false positive rate.

Development of a monitoring system for disassembled towers with internal suspension poles

The traditional construction monitoring methods of suspended pole-mounted decomposed towers are mostly manual monitoring. The monitoring personnel has multiple blind spots, and the possibility of misjudgment based on personal experience is relatively large. It is difficult to ensure the construction safety of the suspended pole decomposing tower. For this reason, combined with the current power Internet of Things technology, this paper develops an intelligent monitoring system for suspended pole-mounted decomposing towers. According to the construction technology and its safety requirements of inner suspension derrick for transmission tower erection in sections, this system is classified into intellisense layer, wireless transport layer and information integration layer.

The average error of critical monitoring point data is 4.14%, and the average data transmission delays in the far and near fields of the system are 18 ms and 176 ms.

A Practical Analysis Report of Rip, EIGRP, And an OSPF Dynamic Routing Protocol using the Network Simulator Tool GNS-3

Routing is crucial in internet “communication” and is based on routing protocols. The routing protocol outlines the rules that routers use to share information between a source and a destination. In contrast, they do not move data from a source to the destination, but instead update the routing table containing data or, as we say, messages or information. Many routing protocols are available today, but they all serve the same goal-static and dynamic routing protocols. Dynamic routing is carried out automatically. Topology-based updates are made to routers, and routing tables are updated when topology changes. As a part of this research study, we will look at and analyze the protocols along with other associated research of RIP, EIGRP, and OSPF. In this study, we provide a practical analysis report by designing and implementing numerous LAN topology scenarios using the emulator (Graphical Network Simulator-3). Because of the proliferation of enormous commercial networks; their design uses a variety of routing protocols. so that a large network can remain connected; Network routers are required to implement route redistribution. This research develops the three phases on the same designed network topology and assesses the presentation of route redistribution across three routing technologies. RIP, EIGRP is the first phase, EIGRP, OSPF is the second, and RIP, OSPF is the third. This research also analyses the compatibility of the two separate versions of routing information protocol on the designed network topology in order to assess how two versions may interact with one other. This offers us the notion that there is a way out of it when the same problem emerges associated to EIGRP, OSPF, or BGP if protocols, as we know, Version-1 and Version-2 do not interact to one other. In this research, we also design the network lAN architecture and setup by utilising GNS-3 in order to evaluate how rip supports merely subnetted networks and eigrp supports major networks.

ML-Based Handover Prediction and AP Selection in Cognitive Wi-Fi Networks

Device mobility in dense Wi-Fi networks offers several challenges. Two well-known problems related to device mobility are handover prediction and access point selection. Due to the complex nature of the radio environment, analytical models may not characterize the wireless channel, which makes the solution of these problems very difficult. Recently, cognitive network architectures using sophisticated learning techniques are increasingly being applied to such problems. In this paper, we propose data-driven machine learning (ML) schemes to efficiently solve these problems in wireless LAN (WLAN) networks. The proposed schemes are evaluated and results are compared with traditional approaches to the aforementioned problems. The results report significant improvement in network performance by applying the proposed schemes. The proposed scheme for handover prediction outperforms traditional methods i.e. received signal strength method and traveling distance method by reducing the number of unnecessary handovers by 60% and 50% respectively. Similarly, in AP selection, the proposed scheme outperforms the strongest signal first and least loaded first algorithms by achieving higher throughput gains up to 9.2% and 8% respectively.

Design of Three Class Internet Protocol Routing Model Based on Linux Command Line Interface

The world of information technology is currently experiencing very rapid development, especially in internet technology. The Internet itself is a form of utilization of a computer network system, a computer network system consisting of a group of computer systems and other computing hardware linked together through communication channels to facilitate communication and resource sharing among various users. TCP / IP is a standard protocol that is applied to the internet network. The existence of a router in a TCP/IP network is very important, this is due to the large number of hosts and the differences in the devices used on a TCP/IP network. Router is a computer network device that is used to forward data packets from one network to another, both within the scope of LAN and WAN networks (Yani A., 2008). As a result, a routing mechanism is needed that can integrate many users with a high degree of flexibility. Routing is generally divided into two categories, namely static routing and dynamic routing. Static routing is a routing mechanism that depends on the routing table with manual configuration while dynamic routing is a routing mechanism where the routing table exchange between routers on the network is carried out dynamically. Routing in the world of information technology (IT) is part of how to improve network performance. Routing is a process to choose the path (path) traversed by the packet. Routing itself is very instrumental in building a network, be it LAN or WAN. Currently the use of routing in a network is something that needs to be taken into account in a company. Today's companies that have business processes in the IT sector are very dependent on network availability. Network reliability is the main point in the operation of the system. An adequate and reliable network infrastructure is very much needed by the company, especially regarding the company's electability. Companies that have large-scale networks need several techniques so that the network can work optimally and reliably in overcoming various problems that arise, including network connectivity that is still not stable and link redundancy has not been implemented as a backup path to overcome network failures if interference occurs. alternative network paths that are used to increase network availability, so that if there is a broken link in a network, the data path can still be connected without affecting the connectivity of devices on the network
