congestion avoid movement aware routing protocol in interplanetary backbone networks

The existing routing protocols for the interplanetary backbone network did not consider future link connection and link congestion. A novel routing protocol named CAMARP for the interplanetary backbone network is proposed in this letter. We use wait delay to consider future link connection and make the best next hop selection. A load balancing mechanism is used to avoid congestion. The proposed method leads to a better and more efficient distribution of traffic, and also leads to lower packet drop rates and higher throughput. CAMARP demonstrates good performance in the experiment. © 2012 The Institute of Electronics, Information and Communication Engineers.The existing routing protocols for the interplanetary backbone network did not consider future link connection and link congestion.
