Abstract

There are some shortcomings in the delay tolerant network (DTN) routing algorithm, such as low message delivery rate, low network efficiency and high cost in the satellite network. In order to solve the problem above, this paper proposes a limited copy algorithm MPWLC based on service probability. In MPWLC, not only is the number of copies limited, but the storage resources of the satellite are also taken into account to ensure reliable data transmission. The simulation results show that the proposed algorithm can effectively improve the efficiency of the network and ensure the reliable data transmission.
