무선 센서네트워크에서 다종 센서(Different Types of Sensors)가 미치는 영향에 대한 분석

Abstract

In this paper, we constructed a sensor network environment where various sensors are used. Then, we evaluated the performance when this environment adopted existing clustering algorithms that are designed for only single type sensors network. In our experiments, we considered two different types of the networks. In the first, all nodes are equipped with identical sensors. In the second, all nodes are equipped with three different types of sensors. We measured performance variations of several clustering schemes in accordance with sensor data accuracy, sensor node ∙제1저자 : 최동민 ∙교신저자 : 김성열 ∙투고일 : 2014. 8. 5, 심사일 : 2014. 8. 17, 게재확정일 : 2014. 9. 3. * 조선대학교 자유전공학부(Div. of Undeclared Majors, Chosun University) ** 조선대학교 컴퓨터공학과(Def. of Computer Eng., Chosun University) *** 울산과학대학교 컴퓨터정보학부(School of Information Technology, Ulsan college) 76 Journal of The Korea Society of Computer and Information September 2014 resource depletion timing, amount of available energy, node isolation ratio, and network lifetime. According to our performance analysis, we proved that existing clustering algorithms are partially inefficient to maintain the various-sensor network. Consequently we suggest that a new algorithm is required to take aim at the various sensor network. ▸
