A Novel Time Interval Routing Protocol in Delay Tolerant Networks

Delay-tolerant networks (DTNs) have the capacity to interconnect the devices in roomy regions unlike today’s networks. In this paper, we propose a routing scheme named Time Interval Routing (TIR) to increase deliver ratio and decrease deliver latency in DTNs. TIR, only using limited and local information as well as simple algorithm, chooses the node in transmission range with the least time interval among neighbors as the next hop. Due to the limited time duration of connections, in this paper, we propose Bundle-Transfer strategies (BTS) mechanisms to ensure that TIR sends the bundle to the destination with the highest possibility. Through comprehensive simulation, TIR displays its advantage over other classic routing schemes in DTNs.
