ABSTRAKSI: Mobile IP adalah protokol internet yang mendukung mobilitas dari host, sehingga setiap host berpindah access point tidak perlu ganti IP, namun masalah yang ada yaitu handover latency dan packet loss akibat proses handover. Dalam Mobile IP ada 2 macam pendekatan untuk penanganan mobilitas, yaitu host-based mobility dan network-based mobility. Pada host-based dibutuhkan keterlibatan mobile node untuk komunikasi dengan home agent melalui network node. Lain halnya dengan network-based, mobile node tidak ikut terlibat dalam proses komunikasi dengan home agent, cukup network node saja yang bertugas mengaturnya. Kondisi jaringan yang ada saat ini ada beberapa lingkungan coverage network seperti WLAN, WiMAX, 3G, LTE. IEEE mengeluarkan standar 802.21 Media Independent Handover Function, pengaturan untuk vertical handover.
Pada tugas akhir ini dilakukan simulasi untuk mengetahui pengaruh handover pada performansi Proxy Mobile IPv6 dengan Hierarchical Mobile IPv6 menggunakan 802.21 MIH pada lingkungan jaringan 802.11 dan 802.16 di domain lokal. Parameter yang dianalisa adalah handover latency, packet loss, throughput, dan delay. Pada domain lokal, Proxy Mobile IP memiliki nilai handover latency, packet loss, dan throughput 20% lebih baik dibandingkan dengan Hierarchical Mobile IP.

In Mobile IP there are two kinds of approaches to the handling of mobility, which is host-based and network-based mobility mobility. In host-based mobile node involvement is needed for communication with the home agent via the network nodes. As with the network-based, mobile nodes are not involved in the process of communication with the home agent, sufficient network nodes are tasked to set it. Network conditions that exist at this time there is some coverage of network environments such as WLAN, WiMAX, 3G, LTE. Standard IEEE 802.21 Media Independent Handover Function had been published for arrangements in vertical handover.
In this final simulation conducted to determine the effect of handover on the performance of Proxy Mobile IPv6 with Hierarchical Mobile IPv6 using MIH 802.21 at 802.11 and 802.16 network environment. The parameters analyzed were handover latency, packet loss, throughput, and delay. In the local domain, Proxy Mobile IP has a 20% better value for handover latency, packet loss, throughput compared to Hierarchical Mobile IP.KEYWORD: Mobile IPv6, Fast handover, PMIPv6, HMIPv6, mobility management, heterogeneous network, MIH
