Abstract

In this paper, we propose a method for improving the lifetime of the sensor network SEP through the wireless sensor network divided into two spaces by reducing the transmission distance of the cluster head in the layer in the distance. With reference to the position information of the node, the base station divides the layer based on the midpoint of the nearest node and the furthest distance away from the base station node. And the cluster head in the outer layer far from the base station is transmitted the data to the base station via the cluster head in the inner layer base station to transmit data. That is, we are proposed the layered SEP by reducing the transmission distance of the cluster head in the outer layer for the energy consumption to a minimum. The proposed algorithm is verified by comparison with the existing SEP.

본 논문에서는 무선 센서 네트워크 공간을 둘로 나누어 멀리 있는 층의 클러스터 헤드의 전송 거리를 줄여 SEP 센서 네트워크의 수명을 개선하는 방법을 제안하고자 한다. 기지국은 노드의 위치 정보를 참고하여, 기지국으로부터 가장 가까운 노드 거리와 가장 먼 노드 거리의 중간 지점을 기준으로 층을 나눈 후, 기지국으로부터 먼 바깥쪽 층의 클러스터 헤드는 안쪽 층의 클러스터 헤드를 경유하여 기지국으로 데이터를 전송한다. 즉, 바깥쪽 층의 클러스터 헤드의 전송 거리를 줄임으로써 에너지 소비를 최소화하는 Layered SEP를 제안하였다. 제안된 알고리즘을 기존의 SEP와 비교하여 검증하였다.
