A general k-anycast DTN routing

K-anycast in disruption tolerant network (DTN) can multi-path custody transfer packets for the area without fully network-coverage Internet access, after gotten circumstance information. In this paper, connection judgment logic is proposed for distinguishing mobile circumstance. Probabilistic routing protocols have poor performance in the mobile node cyclical movement environment, so TTL equivalent was designed to select some paths to k routers, decided by resource allocation model, in n of routers aggregation. Based on the above two, mobile routers on car or on the ground can play roles of ferries and carry the general k-anycast. Simulation shows that connection judgment logic and TTL equivalent have an apparent effect for cyclical movement of the mobile routers.
