Local-world evolving model of wireless sensor networks

Large scale wireless senor networks (WSNs) are used to study complex network theory and a local-world evolving model for wireless sensor networks is presented based on the classic B-A scale-free model. The evolving behaviors in WSNs to the dynamics in this model are introduced. Using the continuum theory and the rate equation method, the expression of the power law degree distribution with the exponent γ=3 is obtained. The model has excellent robustness to the random fault or the failure of nodes, and provides a new reference for constructing reliable topology of wireless sensor networks.
