DEVELOPMENT OF A LIGHT FIDELITY SYSTEM FOR IMPROVING NETWORK PERFORMANCE IN A WIRELESS LOCAL AREA NETWORK

The performance of Wireless Local Area Network (WLAN) is highly dependent on the processes that are implemented in the Medium Access Control (MAC) sublayer regulated by the IEEE 802.11 standard. In turn, various parameters affect the performance of the MAC sublayer, the most important of which is the number of stations in the network and the offered load. With the massive growth of multimedia traffic, research of the network performance depending on traffic types is relevant. In this paper, we present the impact of a high-/low-priority traffic ratio on WLAN performance with different numbers of access categories. The simulation results show different impact of high-/low-priority traffic ratio on the performance of the MAC sublayer of wireless LANs depending on different network-sizes and on network conditions. Performance of the large network with two access categories and with the prevalent high-priority traffic is significantly higher than in the case of using four categories on the MAC sublayer. This allows us to conclude that the performance improvement of the large network with the prevalent high-priority traffic can be achieved by an adaptive adjustment of the access categories number on the MAC sublayer.

<p><span>Wireless local area networks (WLAN) has been used recently due to their benefits which exhibits outstanding mobility with easier and faster configurations. The wireless local area network performance is much influenced by both network topology and hardware specifications and thus will impact the quality of service (QoS) parameters which are delay, load, and response time. This works estimated the performance of WLAN in enterprise WAN based on the OPNET modeler. Three scenarios have been suggested which are FDDI scenario, FDDI Hybrid Star scenario, and FDDI hybrid ring scenario involving web browsing (HTTP) and file transfer protocol (FTP). Hardware objects and software configurations kept the same for all proposed scenarios. Different types of links and topologies have been applied among WLAN subnets as well as the involved gateway has been changed to measure parameters of quality of services (QoS) for all scenarios used. The findings confirmed that the FDDI Hybrid Ring scenario presents better performance than the FDDI Hybrid Star Scenario and FDDI scenario in terms of WLAN delay, WLAN load, FTP download response time, and HTTP object response time.</span></p>

Computer networks today are a much needed service. Computer networks enable the shared use of data, software and tools. So that the working group can be communicate more effectively and efficiently. This study aims to determine the existing QoS in Surya Asih Hospital and analyze the deficiencies. (Bahasa: Hospital is Rumah Sakit (RS)) In this research started from collecting data that exist in location either that support hardware or connection internet RS Surya Asih have used Wireless Local Area Network (WLAN) network service. WLAN is a network where can be exchanged data and resources between computers in one building. To know the performance of WLAN network (Wireless Local Area Network In RS Surya Asih, it should be done a measurement analysis of network performance parameters QoS (Quality of Services) is the ability to guarantee the delivery of important data flow Analysis of the performance of WLAN (Wireless Local Area Network) Surya Asih stressed the process of monitoring and measuring network parameters on the network infrastructure such as access speed and transmission capacity, from the point of delivery to the point of receiver that became the demands, the parameters used Bandwidth, Throughput, Delay and Packet Loss. Superior LAN on RS Surya Asih has reliability sufficient maintenance and good network availability Analysis of network performance is seen through Wireshark, Uptime and Downtime results are not bad, The availability of complete devices and fulfilled according to reliability and maintenance is not difficult. QoS parameter test results that bandwidth management shows the use of more bandwidth and evenly distributed to every user of RS Surya Asih Pringsewu network.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN with advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.
