A model of linear expanding in the local-world based on the laws of internal evolution of the wireless sensor networks

A novel model about the local-world linear expanding evolution of wireless sensor networks(WSNs) has been put forward in the basis of the classic BA scale-free model. The four types of internal evolving behaviors in wireless sensor networks are reflected in the dynamic process of the model. With the application of continuous field theory, the characteristics of network nodes´ degree distribution are obtained, and it follows the power law distribution. This model not only has excellent robustness in avoiding the affection of random fault or failure of nodes, but also provides a new reference for constructing reliable topology of WSNs.
