Messages are stored for a period of time at network nodes and are conveyed hop-by-hop to the destination. The current DTN routing protocols can be summarized into three categories: opportunistic, prediction-based and scheduling protocols.

Based on the characteristics of urban areas, we proposed a kiosk based packet forwarding strategy for vehicular delay tolerant networks. We established the rules of data transmission when one node contacts other nodes. More specifically, Car-to-Car, Car-to-Bus, Bus-to-Bus stop, Bus-to-Bus transfer station, Bus transfer station-to-Bus, Bus stop-to-Car ,Car-to-Destination contacts, have different judgments and restrictions for data forwarding. The simulation results demonstrate that we proposed packet forwarding strategy would reduce the delivery delay, and improve the successful delivery rate. Especially with limited buffer and little overhead, our proposed strategy has the most prominent performance. Tsai, Tzu Chieh 蔡子傑 2012 學位論文 ; thesis 43 zh-TW |

碩士 === 國立政治大學 === 資訊科學學系 === 100 === In Delay Tolerant Networks (DTNs), there does not exist an end-to-end path due to intermittent connectivity and high node mobility. Messages are stored for a period of time at network nodes and are conveyed hop-by-hop to the destination. The current DTN routing protocols can be summarized into three categories: opportunistic, prediction-based and scheduling protocols. However, these routing protocols have some deficiencies and are not specifically focused on the urban areas.
Based on the characteristics of urban areas, we proposed a kiosk based packet forwarding strategy for vehicular delay tolerant networks. We established the rules of data transmission when one node contacts other nodes. More specifically, Car-to-Car, Car-to-Bus, Bus-to-Bus stop, Bus-to-Bus transfer station, Bus transfer station-to-Bus, Bus stop-to-Car ,Car-to-Destination contacts, have different judgments and restrictions for data forwarding.
The simulation results demonstrate that we proposed packet forwarding strategy would reduce the delivery delay, and improve the successful delivery rate. Especially with limited buffer and little overhead, our proposed strategy has the most prominent performance.
