| The wireless sensor network is a new monitoring network. It is a combination of sensortechnology, computer networks, and wireless communications technology, which has a broadapplication prospect, and is regarded as one of the essential technologies in the21st century. Sincethe sensor node itself has some limitations on power, transmission bandwidth, storage capacity anddata processing capabilities, people come to give priority to technologies of improving the efficiencyof data transmission bandwidth, and extending the life cycle of wireless sensor network data fusionin wireless sensor network applications. Data fusion technology is an emerging subject, which hasshowed superior performance in information data processing.Based on the characteristics of wireless sensor networks, this thesis proposes a new evaluationdata fusion operation standard which closely integrated wireless sensor networks and data fusiontechnology and takes a research on neural network data fusion algorithm. And this thesis proposesalso a new standard of the quality for assessment of data fusion, improves two routing protocols,which are E-LEACH (Enhanced LEACH) and C-PEGASIS (Cluster-PEGASIS). The simulationexperiments prove the characteristics of the protocols of energy efficiency and the quality of datafusion, and indicate the superiority of its performance. |
