무선 센서 네트워크의 수명 증대를 위한 개선된 데이터 전달 방법

다국어 초록 (Multilingual Abstract)

In this paper, we modify the previous grouping and data forwarding strategy to maintain the increased wireless sensor network life regardless of the position of the data sink node. The proposed strategy sets the group size with consideration given to the distance between the representative node and the data sink node. Numerical analysis based on the communication energy model and practical assumptions shows that the proposed strategy gives longer network life when the data sink approaches to the center of the network, and when the data reduction ratio of the representative node increases. From this result, it is expected that the long network life can be maintained by choosing the adaptive grouping strategy depending on the position of the data sink node.
