In delay tolerant network(DTN),due to the frequent changes of network topology,there is no stable link between the end to end,so it is one of the key problems in DTN research to select the appropriate relay node for message forwarding and delivering the message to the destination node in a short time.Aiming at the blindness of relay node selection and the lack of reasonable control over message copies distribution in existing routing algorithms,an adaptive spray and wait routing algorithm based on comprehensive performance of node(CPN-ASW)is proposed:in spray phase,a new metric,called as node ...
