Traces and t-Distribution Based Multi-Copy Routing in Delay Tolerant Networks
Ding Li, Kaoru Ota, Mianxiong Dong, Ying Li · 2016
Delay/disruption tolerant network (DTN) is a typical high durable mobile transmission network. The mobile nodes in DTN move around and share information with each other without an end-to-end path in the network. The previous studies reveal that a main characteristic of such network is that mobile nodes in the networks currently move along with several same paths (namely, traces) frequently. Therefore, in such network condition, we look into the recorded traces as part of priorities, while using t-distribution for the future prediction of nodes trends. We propose a novel localized multi-copy mobile network routing algorithm, which utilizes traces to optimize overall benefit of the network. In extensive simulations, the results show that the algorithm gain a better performance than existing routing algorithms.
