In the view of the large scale and increasing kinds of service of space information networks, a service- oriented topology control algorithm is proposed. According to demands of existing service, the topology of network is divided into several logical sub-topologies, on which construct the corresponding topology. Taking the communication pattern as an example, the augmentation-based approach is adopted...
The paper presents a novel method for constructing soft servo networked motion control system via EtherCAT network. The EtherCAT network performance is analyzed in detail through comparison of it by other several industry Ethernet protocols. We give out the application PLC program flow chart of synchronous control. The experiment results show that the soft servo networked motion control system can...
In delay tolerant networks (DTN), flooding mechanism in epidemic routing protocol may waste network resources. Based on introducing and analyzing routing protocols in DTN, this paper proposes an improved protocol of epidemic routing (EPI-HT). EPI-HT forwards messages accurately to the next-hop according to historical information between nodes and node localization principle. Simulation results indicate...
