| Abstract: | Sensor network is used in the course of controlling, collecting, processing and transmitting information, and it appears many excellent features such as accuracy, real-time, convenience, redibility, etc. So more and more countries'military, academia and industries pay high attentions to sensor network. In this paper, the problems of storing the nodes' information repeatedly is analyzed in detail. Focused on the problems, a method of using singly linked lists to store the same document fragments between siblings is presented, and the problem of data redundancy is solved effectively. |
