Feedback Adaptive Routing Algorithm for DTN

Routing in DTN (delay tolerant network) is a considerably different and more challenging problem. In this paper, we propose a feedback adaptive routing algorithm. Nodes evaluate routing influence of other nodes in the network based on the feedback of routing results. and first transmit messages through nodes with higher influence factor.The experiment shows that the high performance nodes transmit the majority messages, and the majority of nodes do not need to save too many messages. The algorithm can achieve high delivery ratio and save node buffers.
