ABSTRACT
With the rapid development of spatial information network, LEO satellite network is playing an increasingly important role in various fields because of their low cost, low transmission delay and high coverage. However, due to the large number and fast movement speed of nodes, the LEO satellite network has a high dynamic network topology and limited available on-board resources, which make the traditional methods cannot be applied to the network with good performance. According to the requirements of inter satellite cooperation and autonomous networking in LEO satellite network and its own characteristics, we can use the idea of ad hoc network for reference when designing algorithms for LEO satellite network. We propose a proactive routing algorithm based on OLSR. Nodes can obtain network information through periodic control messages, and dynamically adjust the sending interval and size of control messages according to the current network status. At the same time, we use the mechanism of multipath transmission in parallel to optimize the algorithm overhead, balance the load between nodes, and improve the network performance and resource utilization while ensuring the transmission demand.
