modeling and analysis of dtn in metropolitan bus network
DTN is an approach to communicate in easily disrupted or delayed networks. Examples of such networks are often found in heterogeneous networks, mobile or extreme terrestrial networks, or planned networks in space. Recently, many studies have used wireless LAN in a DTN environment because the WLAN offers easy installation, competitive price, and popular Wi-Fi devices. This paper is about modeling and analyzing the metropolitan bus network as a DTN environment. Modern metropolitan bus networks already offer IT services such as BIS; however, their networks may be appropriate for communicating narrow-band data in real time, but not for wide-band data in a DTN environment. In order to apply WLAN as an alternative solution for communicating wide-band data in DTNs, we need to understand the DTN characteristics of metropolitan bus networks. We perform spatial, temporal, and mobility modeling via simulation. Based on our simulation results, we provide qualitative and quantitative analysis reports about the use of WLAN in metropolitan bus networks.
