Research On Artificial Spiderweb Routing Algorithms Oriented Smart Grid

Communication networks of smart grid is transforming from traditional SDH network to MESH network.Although MESH network can well resist multipath interruption, its routing protocols are not perfect, and the application of traditional IP routing protocols to MESH network is limited,thus makes it a bottleneck in the application of MESH network in communication system of smart grid. To solve this problem, this paper proposes a routing algorithm, which is inspired by the spinning and predation behavior of spiders and can be better applied in MESH network.First, this paper introduces the current researches on smart grid, analysises the performance requirements and topology structure of smart grid communication networks, and compares network topologies of smart grid.Second, the topological structure of natural spiderweb and the transferring mechanism of vibration information in spiderwebs are discussed, and the similarities between artificial spiderwebs and existing communication networks are compared and analysed. Based on this,an artificial spiderweb network model is built. And with Factorization Theorem reliability analysis of artificial spiderweb network model and traditional network model is conducted, which will lay theoretical foundation for the simulation analysis of subsequent chapters.This paper then studies the general standardization method of transforming backbone communication network topology of smart grid into standard artificial spiderweb model, which will lay foundation for the application of artificial spiderweb routing algorithm in smart grid. Artificial spiderweb routing algorithm introduces the principle of label switching in multi-protocol label switching (MPLS), which can meet the demand for fast forwarding data packets.Finally, the simulation models of artificial spiderweb model and irregular MESH network are built with simulation software OPNET, and the average packet loss rate, end-to-end delay etc. of single-layer artificial spiderweb model are compared with that of star, ring, double star and double ring networks.The simulation results indicate that artificial spiderweb network standardization method and routing strategies have good network communication performance and can be used in the communication system of smart grid.
