A source routing algorithm for LEO satellite networks

摘要

One research challenge in low earth orbit (LEO) satellite networks is to develop specialized and efficient routing algorithms. Based on datagram routing algorithm (DRA), a new routing algorithm, namely source routing algorithm (SRA), for LEO satellite networks is presented. Compared with DRA, it reduces computation overhead greatly while keeping the same overall performance. By the algorithm, the path with minimum propagation delay is discovered at the source satellite and stored in packet header, and then the packet is forwarded to its destination by intermediate nodes according to the path. Finally, the algorithm performance is evaluated through simulation and its computation complexity is analyzed to validate the efficiency of SRA.
