The LEO network composed of massive satellite nodes is a hot research field at present. In such a network, the problem of load balancing should be reconsidered due to the large number of satellite nodes, the frequently changing topology, and the uneven distribution of global ground users. To solve such problem, a selective iterative Dijkstra algorithm (SIDA) is proposed to optimize the path finding process by reducing the reuse frequency of nodes. On the basis of SIDA, a selective split load balancing strategy (SSLB) is proposed to solve the link congestion problem in low latitude LEO network. SSLB is a distributed strategy, which diverts the traffic flow of congestion nodes to neighboring nodes. SSLB reduces the burden of neighbor nodes, which need the less demand of computing resources and signaling interaction. Simulation results show that SIDA reduces the number of congestion links and balances the load distribution, while SSLB can effectively suppress the number of new congestion links after traffic diversion. These algorithms provide a load balancing solution for LEO satellite network.

“…The proposed scheme uses distributed method to complete packet forwarding. For [7] and [8], both requires frequent signaling to achieve global state synchronization, which can be heavy burden for the network. Therefore, in [9], the authors proposed a load balanced on demand routing scheme.…”

“…There are some works involving load balancing routing algorithm in previous studies. [14][15][16] The work in Karapantazis et al 14 proposed a location-assisted ondemand routing (LAOR) protocol which is a typical centralized algorithm for LEO satellite systems. This protocol can be viewed as a variant of the ad hoc ondemand distance vector (AODV) routing protocol, tailored to the requirements imposed by the characteristics of LEO satellite system topology.…”

In order to implement global precision navigation, the global navigation satellite system must rely on information exchange with the ground station to achieve system time synchronization and inter-satellite ranging. For the limitations of ground stations located in territory and actual communication requirements, it is essential to study the routing problem of navigation satellite network, which indicates that traditional routing technology cannot meet the requirements of global navigation satellite system. Aiming to control the dynamic topology of global navigation satellite system and satisfy communication constraints, we investigate the topology-adapting strategy for inter-satellite link constructing and routing. First, we propose the design method of the inter-satellite link scheme based on fixed topology to satisfy the requirements for delay and relay hops. Then, we build the constraint programming model of the global navigation satellite system routing problem. In further, we design the routing calculation framework and optimization strategies to enhance the routing performance of the transmission scheme. Through the simulation and numerical results, we demonstrate that the fixed topology scheme can meet the navigation requirements, and the proposed strategy can effectively improve the routing performance.

Low Earth Orbit (LEO) satellites networks can provide multimedia service and plays an increasing1y important role in the exploitation of space. However, one of the challenges in LEO satellites networks is that the services are suffered from high symbol error, limited storage space and limited available energy. To analyze the performance of the service in LEO satellites networks, a model, based on differential game, is proposed for satisfying the QoS requirements of multimedia applications. The controller of our model is the transmitting rate and the object is to maximize the payoff depending on the error symbol rate, the available energy, the bandwidth and the process ability so as to guarantee the QoS service.In order to solve our built model, we use the Bellman theorem to make formulas on the trance of the optimal transmitting rate. Furthermore, simulation results verify that the service can be maximized by using our derived transmitting rate trance.
