Abstract

In the era of globalization, computer networks are developing very rapidly and complex human needs make it possible to exchange information and communicate over long distances. In order for video streaming service providers from servers to be accessed by service users, it requires a process of sending data packets through a path called routing. OSPF is a routing protocol that applies network speed based on metrics to consider paths to other networks. EIGRP is a routing protocol that applies bandwidth and delay-based formulas to calculate metrics to determine routes. EIGRP is a type of Dynamic routing protocol. Throughput on OSPF and EIGRP differs depending on video quality. Jitter values on OSPF and EIGRP vary depending on the quality of the video used. There is a difference in the delay time experienced for each video quality when using OSPF and EIGRP. At all video quality levels, no packets are lost using either OSPF or EIGRP routing. OSPF and EIGRP performance is sufficient in sending video data. Throughput parameters, EIGRP has better performance than OSPF for all video qualities. However, for the jitter parameter, OSPF has better performance than EIGRP at 360p and 480p video quality. While on the delay parameter, both protocols have the same good performance. In the packet loss parameter, both protocols have the same performance without packet loss.

Abstract

Wireless Sensor Networks (WSN) dalam IoT memungkinkan pengumpulan data dari lingkungan sekitar, namun menghadapi tantangan jarak, jumlah node, dan daya baterai terbatas. Penelitian ini menganalisis WSN dengan protokol Multi Hop dan Single Hop melalui simulasi. Metode penelitian melibatkan studi literatur, perancangan model jaringan, dan analisis performa. Hasilnya menunjukkan Protokol Multi Hop (AODV) dengan throughput tinggi pada jumlah node 30 sebesar 269,38 kbps untuk pengiriman data cepat, sedangkan Protokol Single Hop (Cluster Head) lebih baik dalam pengiriman paket pada jumlah node 30, protokol Single Hop memiliki PDR sebesar 99,81%. Hal ini dikarenakan protokol Single Hop tidak melibatkan transfer data melalui node perantara. Dari segi konsumsi energi, , protokol Single Hop memiliki konsumsi energi sebesar 2595,72 Joule pada jumlah node 30. Protokol Single Hop lebih efisien berkat pengelompokan dimana node-node di dalam satu kelompok hanya perlu berkomunikasi dengan node cluster head. Hal ini dapat mengurangi frekuensi komunikasi antar node dan, pada akhirnya, mengurangi konsumsi energi. Secara umum, protokol Single Hop lebih unggul daripada protokol Multi Hop dalam hal PDR, packet loss, dan konsumsi energi. Namun, protokol Multi Hop dapat memiliki keunggulan dalam hal throughput pada aplikasi WSN dengan jumlah node yang kecil dan jarak komunikasi yang jauh. Penelitian ini menunjukkan bahwa pemilihan protokol WSN harus disesuaikan dengan kebutuhan aplikasi dan lingkungan.

Abstract

Mobile Ad-hoc Network (MANET) technology is a wireless network consisting of a random and dynamic set of nodes. Free flow and ever-changing nodes lead to unpredictable routes throughout the network, so a routing protocol is required to determine the path of each node. Therefore, a study was conducted to analyze the performance of routing protocols based on their characteristics, namely proactive and reactive. The proactive routing protocol tested is DSDV and the reactive routing protocol uses AODV. Based on the research conducted, it can be concluded that the reactive routing protocol, AODV, has better performance than the proactive routing protocol, DSDV, measured by three Quality of Service (QoS) parameters, namely Packet Delivery Ratio (PDR), throughput, and average delay.

Abstract

Universitas Kristen Satya Wacana (UKSW) is one of the private universities in Indonesia that actively utilizes internet technology and its Website to support academic and non-academic activities. SIASAT (Satya Wacana Academic Information System) provides important information confidentially to the community or makes this information only accessible to users who have an account. Regarding security, SIASAT has experienced problems, and threats such as SQL Injection, brute force, and so on which still happen frequently. Problems related to the security and confidentiality of data in computer networks are Privacy (confidentiality) data must be kept away from unauthorized parties. Integrity (integrity) ensures that the information sent remains intact or without changes. Authenticity (authenticity) is a procedure for knowing that a user is truly authorized to access a system. Authenticity could be password, PIN, fingerprints, or other identification. Non-repudiation (irrefutable proof) is proof to ensure that the user has full access to the services used in a system. A system can be categorized as unsafe if the above issues cannot be met. Therefore, by using Footprinting and vulnerability scanning techniques, analysis can be carried out on the SIASAT Website to overcome this problem. This research was carried out using an approach of ethical Hacking, with an emphasis on level Footprinting and vulnerability scanning. The results of this research have found information related to the SIASAT Website and several vulnerability warnings after scanning with high to low-risk levels.

Abstract

In the management of SDN networks, the main challenges faced are traffic congestion and network overload. One of the solutions that has been implemented is the Random Early Detection (RED) algorithm. This research aims to analyze the performance of SDN networks with the implementation of the RED algorithm compared to SDN networks without the use of the RED algorithm. The results of the study show that the use of the RED algorithm (Random Early Detection) in SDN networks has a significant impact on Quality of Service (QoS) parameters, such as packet loss, throughput, and average delay. In high load conditions, there is a controlled increase in packet loss with RED as the number of hosts increases. The average packet loss with RED is 1.57% for 4 hosts, whereas without RED, it is only 1.4%. RED also has a positive impact on throughput, with an average throughput of 243.8 kbps for 4 hosts with RED, while without RED, it only reaches 124.3 kbps. Furthermore, the use of RED reduces the average delay in packet delivery. The average delay with RED is 3.8 ms for 4 hosts, whereas without RED, it reaches 5.92 ms.
