"Skripsi ini membahas tentang aplikasi Voice over Internet Protocol (VoIP) pada jaringan Mobile IPv6 (MIPv6) dengan menggunakan mekanisme komunikasi bidirectional tunneling. Jaringan MIPv6 sederhana yang dirancang akan diserang menggunakan variasi ukuran paket serangan Ping of Death sebesar 1 kB, 10 kB dan 100 kB untuk mendapatkan perubahan Quality of Service tertentu, yakni delay dan throughput, pada layanan VoIP. Kemudian akan dilakukan uji coba penyerangan pada variasi jenis codec (G.711, G.723.1 dan G.729) untuk menentukan jenis codec yang paling baik untuk digunakan pada jaringan Mobile IPv6 dengan ancaman keamanan Denial of Service. Data hasil simulasi menunjukkan bahwa pada Home Network peningkatan delay mencapai 652,83 % dan penurunan throughput mencapai 57,05 % untuk serangan 1 kB, peningkatan delay 908,87 % dan penurunan throughput 60,95 % untuk serangan 10 kB dan peningkatan delay 2871,30 % dan penurunan throughput 61,75 % untuk serangan 100 kB. Codec G.723.1 merupakan codec yang paling baik digunakan untuk aplikasi VoIP pada environment ini dengan nilai delay paling kecil, yakni 147,94 ms di Home Network sebelum serangan dan 2,3 s setelah mendapat serangan, serta 4,9 s di Foreign Network sebelum serangan dan 10,8 s setelah mendapat serangan.

This paper discussing about Voice over Internet Protocol(VoIP) application in Mobile IPv6 (MIPv6) network using bidirectional tunneling mechanism. The simple MIPv6 network is going to be attacked using variant sizes of Ping of Death packets which are 1 kB, 10 kB and 100 kB to breakdown the certain Quality of Service, which are delay and throughput, on VoIP services. Then the attacking experiment to the variant of codec (G.711, G.723.1 and G.729) will be conducted to determine the recommended codec to be used for MIPv6 network which faces the security threats of Denial of Service.

Simulation data shows that in Home Network the delay increased by 652,83 % and the throughput decreased by 57,05 % for 1 kB Ping of Death, delay increased by 908,87 % and throughput decreased by 60,95 % for 10 kB Ping of Death, delay increased by 2871,30 % and throughput decreased by 61,75 % for 100 kB Ping of Death. Codec G.723.1 is the most recommended codec for VoIP application to be used in this kind of environment with the least delay value, which is 147,94 ms in Home Network before the threat occured and 2,3 s after the threat occured, and then 4,9 s in Foreign Network before the threat occured and 10,8 s after the threat occured."

"Jaringan Mobile IPv6 mendukung perpindahan mobile node dari titik akses jaringan satu ke titik akses lain tanpa harus memutuskan koneksi. Pada jaringan mobile, perpindahan ini disebut handover yang dibedakan atas vertical handover dan horizontal handover. Untuk mengetahui performa jaringan dengan kedua jenis handover tersebut, dapat diukur beberapa parameter QoS seperti throughput, transfer time, dan delay. Dalam skripsi ini, aplikasi yang digunakan berupa File Transfer Protocol (FTP). Hasil pengukuran membuktikan bahwa throughput mengalami penurunan sebesar 4,14% pada horizontal handover dan mengalami penurunan sebesar 26,25% pada vertical handover; transfer time bertambah sebesar 8,34% pada horizontal handover dan bertambah sebesar 41,49% pada vertical handover; delay bertambah sebesar 8,22% pada horizontal handover dan bertambah sebesar 41,05% pada vertical handover. Secara keseluruhan performa jaringan mobile IPv6 skenario horizontal handover lebih baik daripada vertical handover.

Mobile IPv6 network supports mobile nodes movement from one location to another within the network without having to disconnect. In mobile networking, the movement is called handover which is divided into vertical handover and horizontal handover. To determine the network performance with both types of handovers, we can measure several QoS parameters such as throughput, delay, and transfer time. In this final paper, application that is used is the File Transfer Protocol (FTP).

Measurement results prove that the throughput decreased by 4.14 % in horizontal handover and decreased by 26.25 % in vertical handover; the transfer time increased by 8.34 percent in horizontal handover and increased by 41.49 % in vertical handover; the delay increased by 8.22 % in horizontal handover and increased by 41.05% in vertical handover. Overall, network performance of mobile IPv6 on horizontal handover scenario is better than the vertical handover."

"Mobile IPv6 merupakan komunikasi perangkat mobile yang memungkinkan koneksi tetap terhubung meskipun berpindah dari Home Network ke Foreign Network. Dalam mempertahankan koneksi, terdapat berberapa metode, salah satunya adalah Bidirectional Tunelling. Jaringan Bidirectional mobile IPV6 dengan aplikasi FTP yang di rancang akan diuji performanya dengan serangan Distributed Denial of Service yang dibedakan besar paket data serangannya. Parameter pengukuran yang digunakan adalah transfer time, delay, throughput, dan packet loss. Transfer time, delay, dan packet loss di Home Network saat diserang DDoS 2600KB mencapai kenaikan 392.78%, 372.46%, dan 11446.48. Sedangkan throughput di Home Network saat diserang dengan DDoS 2600KB mencapai penurunan 77.83%. Performansi jaringan dengan aplikasi FTP di Home Network memiliki kinerja yang lebih baik dibandingkan di Foreign Network. Dari hasil pengukuran dapat disimpulkan semakin besar paket data serangannya maka semakin berpengaruh terhadap buruknya parameter tersebut. Namun dengan semakin besarnya paket data serangan maka semakin lama pengiriman flooding paket data tersebut akibat pemrosesan yang semakin berat juga. Hal tersebut yang mengakibatkan perbedaan persentase terlalu signifikan pada paket data serangan yang terlalu besar.

Mobile IPv6 is a communication between mobile devices which allow the connection stays alive even move from the Home Network to the Foreign Network. In maintaining the connection, there are some of methods, one of them is Bidirectional Tunneling. Bidirectional mobile IPv6 network with FTP application which is designed will be tested its performance with the Distributed Denial of Service attack which is distinguished its large attack data packets. Measurement parameters used are the transfer time, delay, throughput, and packet loss. Transfer time, delay, and packet loss in the Home Network when its attacked with DDoS 2600KB increase 392.78%, 372.46%, and 11446.48%. While the throughput in the Home Network when its attacked with DDoS 2600KB decrease 77.83%. This network performances with the FTP application in the Home Network has a better performance than in the Foreign Network. The measurement result, bigger attack data packet which is used will be more powerful against bad that parameters. But bigger attack data packet make sending flood data packet slower because the process is harder too. This thing that causing the percentage difference is not too significant on attack data packet which is too big."

"This book presents solutions to the problems arising in two trends in mobile computing and their intersection: increased mobile traffic driven mainly by sophisticated smart phone applications; and the issue of user demand for lighter phones, which cause more battery power constrained handhelds to offload computations to resource intensive clouds (the second trend exacerbating the bandwidth crunch often experienced over wireless networks). The authors posit a new solution called spectrum aware cognitive mobile computing, which uses dynamic spectrum access and management concepts from wireless networking to offer overall optimized computation offloading and scheduling solutions that achieve optimal trade-offs between the mobile device and wireless resources. They show how in order to allow these competing goals to meet in the middle, and to meet the promise of 5G mobile computing, it is essential to consider mobile offloading holistically, from end to end and use the power of multi-radio access technologies that have been recently developed. Technologies covered in this book have applications to mobile computing, edge computing, fog computing, vehicular communications, mobile healthcare, mobile application developments such as augmented reality, and virtual reality.- Gives readers valuable insights into the future of mobile computing and communication;- Touches on wireless technologies such as 5G, mobile edge computing (MEC), mobile cloud services, and cognition-based networking; - Provides examples throughout the book to provide insight into real world scenarios."

Mobile applications on the transportation sector in Indonesia are increasingly being used. MRT-J is a mobile application in the field of transportation that helps users to use MRT Jakarta. Although the MRT-J mobile application can make it easier for users to use MRT Jakarta, there are several problems with the application. This study aims to identify problems in the transportation and financial aspects of the application and provide solutions in the form of alternative interface designs. The design of alternative interface designs in this study uses the User-Centered Design method by applying the interaction design principles of Shneiderman's Eight Golden Rules of Interface Design and Nielsen's Ten Usability Heuristics. Research data was collected by distributing online questionnaires, Usability Testing (UT), and distributing System Usability Scale (SUS) questionnaires. Data in the form of complaints and suggestions are analysed and the results of the analysis are used to design solutions in the form of alternative interface designs that include transportation and financial aspects, namely the ticket purchase feature, view schedule, payment and my card. After the solution design process is completed, the solution is evaluated with UT and SUS. The results of the evaluation of the solution are then compared with the results of the evaluation of the current application (as-is). It was found that the value of SUS has increased in the transportation and financial aspects. SUS in the transportation aspect scored 95.75, previously 51.5, and SUS in the financial aspect scored 92.75, previously 55.25. These values exceed the value of 80 which is the benchmark to determine a product has an above average level of User experience."

"Mobile IPv6 memiliki dua metode dalam komunikasi antara mobile node dengan corresspondent node, yaitu Bidirectional Tunneling dan Route Optimization. Bidirectional Tunneling tidak membutuhkan bantuan correspondent node dan dapat tersedia walaupun mobile node tidak meregistrasi binding terbarunya terlebih dahulu. Route Optimization memerlukan dukungan mobile node untuk meregistrasi binding-nya pada correspodent node. Proses handover pada MIPv6 dibagi manjadi dua, yakni horizontal handover dan vertical handover. Horizontal handover merupakan handover yang terjadi pada saat mobile node berpindah access point namun masih berada pada Home Network yang sama, sedangkan vertical handover merupakan handover yang terjadi pada saat mobile node berpindah dari Home Network ke Foreign Network. Akan dijelaskan mengenai perbandingan performansi throughput, packet loss, dan delay antara Bidirectional Tunneling dengan Route Optimization menggunakan aplikasi HTTP. Hasil pengukuran pada home link, didapatkan throughput pada bidirectional dan route optimization memiliki perbandingan 15.7%, pada pengukuran packet loss memiliki perbandingan 0.007%, dan pada pengukuran delay memiliki perbandingan 1.77%. Hasil pengukuran pada foreign link, didapatkan throughput pada route optimization 36.77% lebih cepat dibandingkan bidirectional tunneling. Paclet loss pada route optimization 1.76% lebih sedikit dibandingkan bidirectional tunneling, dan pengukuran delay pada route optimization 41.45 lebih cepat dibandingkan bidirectional tunneling.

Mobile IPv6 has two methods in communication between mobile node with correspondent node, those are Bidirectional Tunneling and Route Optimization. Bidirectional Tunneling does not need help of correspondent node and no need registration of binding from mobile node. Route Optimization requires support of mobile node to register the binding on correspondent node. MIPv6 handover process is divided into two, those are horizontal handover and vertical handover.

Horizontal handover is a handover that occurs when the mobile node moves to the other access point but still in the same Home Network, while vertical handover is a handover that occurs when the mobile node moves from Home Network to Foreign Network. Will be explained about the comparative performance of throughput, packet loss, and delay between Bidirectional Tunneling with Route Optimization using HTTP applications. Measurement result on home link, shows the throughput on bidirectional tunneling and route optimization having comparison about 15.7%, packet loss about 0.007%, and delay about 1.77%.

Measurement result on foreign link, shows that throughput on route optimization is 36.77% faster than on bidirectional tunneling. Packet loss on route optimization is 1.76% lesser than bidirectional tunneling, and measurement of delay on route optimization is 41.45% faster than bidirectional tunneling."
