Efisien Epidemic: Pemilihan jarak terjauh dan arah pergerakan kendaraan untuk pendistribusian pesan darurat pada VDTN

Abstract

VANET has characteristics of high mobility vehicles and fast changes of the topology, it causes process data communication interrupted frequently. It can be minimized by Vehicular Technology Delay Tolerant Networking (VDTN). The Epidemic protocol is one of which was used to the distribution of message on VANET, the mecanism of Epidemic protocol caused amount of message, thus impacting in distribution unefficient message and the performance can be lower.The porposed of this research are to solve the problem of Epidemic protocol, namely e-Epidemic protocol. This proposed protocol are the development of Epidemic protocol that give more attention on the vehicles direction and farest vehicle.The results based on the number of messages distribution showed the number of messages average which owned e-Epidemic protocol is 8% whereas epidemic protocol is 92%. And based on the delay value, e-Epidemic protocol only has delay as much as 17%, meanwhile epidemic protocol has delay 83%.

Impelementasi High Availability Mailbox Server dengan Mail Zimbra Multi Cluster Virtual Menggunakan Hypervisor Proxmox VE pada PT. LV Logistics Indonesia

“…Dengan mempunyai banyak link maka optimalisasi kegunaan sumber daya, throughput, dan time response akan semakin baik karena mempunyai lebih dari satu link yang bisa saling membackup pada saat network down dan menjadi cepat pada saat network normal jika memerlukan kehandalan tinggi yang memerlukan 100% koneksi uptime yang berbeda dan dibuat saling membackup. Di implementasikan metode ini pada layanan mail server juga dapat meminimalisir dampak dari terjangan trafik email maupun spam email, dikarenakan bila mana server terjadi masalah / down, metode cluster dapat untuk membuat cadangan sistem agar tetap berjalan dengan normal [4].…”
