Abstract:

Considering that the nodes with limited energy are prone to be failure in wireless sensor networks and introducing energy and node degree adjustment parameters, an energy efficient scale-free topology model was constructed based on the complex network theory. The node residual energy is limited according to node radius and topological index can be changed within with full consideration of the factors such as the node residual energy and the node degree. Analysis on the topology dynamic behavior and simulation afterwards show that this model has power rate characteristics of scale-free networks and good fault tolerance and the energy balance characteristics.

Key words: wireless sensor networks, scale-free, energy, fault tolerance
