[Abstract]:Due to the limited energy of wireless sensor, maximizing the network life cycle becomes the most important problem to optimize the network topology. Based on the scale-free theory of BA, a WSNs topology optimization model, (WTOM)., is proposed. The super node is introduced into the network, and the whole network is divided reasonably with the particle swarm optimization (PSO). A multi-factor oriented virtual force field is established between nodes and the deployment position of super nodes is adjusted by virtual force to realize the balanced consumption of network energy. Through the protection of key nodes the robustness of the network is improved. It is proved by theoretical analysis and experiments that the network not only inherits the characteristics of BA scale-free network but also has small-world characteristics, and the dynamic topology prolongs the lifetime of the network and improves the energy saving of the network for data collection.
