Performance Evaluation of DTNs Routing Protocols on Train System by Variations in Message Volume

Abstract

Abstract:In this world, there are areas, the villages that have not received the spread of messages (e.g. goverment's information) through Internet. For the villages that are be served by scheduled public transports systems at least once a day there is an opportunity to receive messages from the Internet. The public transports serve as relay nodes that carry the messages from the cities that are to be sent to the villages. This paper compares Delay and DisruptionTolerant Networks (DTNs) routing protocols to solve the problem of the spread of messages. The scenario is made based on the local map with realistic environment. The parameters used in the simulation are the speed of public transport 1.478 m/sec, some transmit ranges, several buffer sizes, and some message sizes by number of differences. The simulation shows that the routing protocol MaxProp gets better delivery probability than other routing protocols. However, all the routing protocols produce better delivery probability on larger size and smaller number of messages.

“…Salah satu upaya dalam memenuhi ketersediaan infrastruktur jaringan internet adalah melalui penyediaan "Media Center" (Wibowo et al, 2017). Agus Urip Ari Wibowo menyatakan dalam penelitiannya, bahwa Media Center menjadi media informasi publik pada penyebaran, pertukaran informasi, serta layanan informasi dan komunikasi publik.…”
