Abstract:

Computing the whole energy consumption of wireless sensor networks, analyzing the key factors of influencing the energy efficiency, and then optimizing the energy efficiency of networks are necessary to improve the whole energy efficiency. An energy model to evaluate the upper bound of energy consumption in wireless sensor networks based on the capacity of networks is proposed,beginning with analyzing the nodes status in data transferring. The optimum routing design for the network of link architecture is implemented using this model.

Key words: wireless sensor networks, upper bound of energy consumption, energy model
