Abstract: In wireless sensor networks,the reliability of data fusion is a very important issue.It has been widely concerned.Thus,a trust and weight based data fusion model (TWDFM) was proposed in this paper.In this model,sensor nodes elect reliable cluster head by building trust tables,and cluster head detects abnormal nodes according to the weights and fuses the credible data.The results of simulation show that this model can effectively improve the safety and accuracy of data fusion.

Key words: Wireless sensor network,Trust,Weight,Data fusion
