Abstract
The cooperative microsatellite swarm network has the advantages of low construction cost, short development cycle, flexible working mode and strong anti-destruction ability. In the network, micro-satellite nodes need to complete network control functions such as link maintenance, state monitoring and routing calculation. The valuable on-board payload and inter-satellite link resources are consumed. In order to reduce the energy consumption of satellite communication transmission, this paper focus on the routing issue in swarm network. A specific routing protocol is proposed, which defines the uniform format of swarm network packets suiting for path addressing based multi-hop transfer and the header deletion technique based packet routing scheme. An algorithm for optimal routing in swarm networks is devised, in which the transmission power consumption and the transfer time delay are chosen as the primarily concerned factors. The routing problem is mathematically formulated as a constrained optimization problem, with the total transmission power consumption of satellites as the optimization objective and with the transfer time delay as the constraint respectively. Then the graph theory approach is utilized as the tool to solve the problem. Examples are used to demonstrate the performance and efficiency of the proposed routing protocol and algorithm.
