Abstract

In recent years, with the advancement of aerospace integration and the development of space missions, micro-nano satellites have become a hot research direction in aerospace field. Limited by the performance limitations of single micro-nano satellites, the networking of micro-nano satellite constellation is becoming the main trend. Optimized Link State Routing (OLSR) protocol is widely adopted as the micro-nano satellite networks routing protocol. For the micro- nano satellite constellation networks, frequent changes of the network topology caused by the rapid movement of satellite nodes pose a high challenge to the invulnerability of routing protocols. However, traditional OLSR routing protocol lacks awareness of the satellite node running trajectory and running status, resulting in untimely updates of network topology changes, the invulnerability cannot be guaranteed. To this end, in view of the predictability of the micro-nano satellite constellation orbit, we propose an improved OLSR protocol based on link survival time optimization. By adding the interaction of position and other information in OLSR protocol, link survival time is predicted based on satellite orbit. Extensive simulation experiments show that improved OLSR protocol based on link lifetime optimization has significantly improvement in transmission success rate and invulnerability.
