Wireless Sensor Network is a micro-embedded-networked system with severe resource constraints. Energy-limited is one of the biggest challenges in application system design. This paper represents an optimized model of energy-effective,based on heterogeneous and hierarchical characteristics of wireless sensor network,with a top-down hardware/software co-design method. Thanks to energy-distribution according to energy-required,avoiding complicated routing algorithm and network consumption,the model gets a great performance of energy-effective compared with energy-homogeneous models.
