Delay Tolerant Network (DTN) can modify frequent network disruption and segmentation in mobile Internet access. Its core technology includes routing resource allocation. However, the existed knowledge oracles of DTN routing algorithms are time probabilistic uncertainty in public transport means mobile network or logistics, which reduces the efficiency of resource allocation. So it was proposed that general k-anycast allocates bandwidth resources to k eligible access routers in access period, which diversify the time deviation degrees and decrease the uncertainty. And access router information matrixes decide general k-anycast router aggregation. Therefore packets can be transmitted simultaneously to multiple destinations. The probabilistic uncertain utility model was further proposed for routing resource allocation based on DTN custody transfer. Simulations show that its transmission performance and robustness are better than Multicast DTN routing algorithm.
