K-anycast DTN Routing in Predictable Environment

Access to Internet is still a challenge in the area without fully network-coverage. Limited to a predictable environment (such as trains), the problem can be simplify and be solved partially with the proposed general k-anycast routing and Delay and Disruption Tolerant Networking (Ganycast). How to forward the packets efficiently is core issue of Ganycast. Access router information matrixes were proposed to help decide k in k-Anycast router aggregation. k Routers on car or on ground play roles of ferries and achieve DTN custody transfer. In order to avoid packets custody transferred have excessively redundant duplication, Address book multicast informing (ABI) policy was introduced. Based on Pareto distribution of correspond routers communication traffic concentration, ABI can improve accuracy of prediction and achieve routing validity. Simulation on NS2 shows a good result.
