Adaptive Parameter Estimation Based Congestion Avoidance Strategy for DTN

摘要：

　　Delay Tolerant Networks are characterized by intermittent connectivity,long delays and often constrained bandwidth.Delay Tolerant Networks often use multi-copy routing schemes for message transmission.Multi-copy routing schemes,such as Epidemic Routing,usually lead to congestion problems.In this paper,we propose an Adaptive Parameter Estimation based congestion Avoidance strategy (APEA) forDelay Tolerant Networks.The APEA strategy includes buffer management policy and packet receiving policy.The buffer management policy is designed for improving the delivery ratio,and the packet receiving policy is designed for reducing the network overhead.The simulation results show that the APEA strategy significantly improves the delivery ratio and reduces the network overhead,compared to the default Drop-First-Received strategy.
