Research on Key Issues of Message Ferry-Based Routing in DTN

Due to the sparse distribution of the DTN nodes,the randomness of node mobility and the uncertainty of communication,the network topology frequently changes,communication links are often interrupted and the propagation delay is relatively long,which directly affect the DTN network performance.The Message Ferry-based routing mechanism provides an effective means to improve the performance of DTN network.This paper concentrated to the target node selection technology of Ferry and proposed the Multi-Constraint Target Selection Algorithm(MCTSA).
