Mobile Sink Based Energy Efficient Path Setup Method for Wireless Sensor Networks

Abstract

In this paper, we propose a novel method for path setup that optimizes energy consumptions for wireless sensor network. Existing studies usually generate paths according to Random way point approach so that it requires unnecessary energy consumptions for estimating location of the mobile sink node and transmission paths of packets. To address this problem, we propose a method that creates paths for mobile sink node using the Hilbert curve. Moreover, our method adjusts the path of the mobile sink node according to the density of sensor nodes to minimize data transmission delay. In our experiments, the proposed method outperforms existing work such as TTDD and CBPER by up to 50times in terms of energy efficiency.First Author : LIG Nex1, seunghyun.yang@lignex1.com, 정회원°C orresponding Author : LIG Nex1, victorson@lignex1.com, 정회원 * LIG Nex1, soongyeol.lee@lignex1.com, emessage@lignex1.com 논문번호：KICS2014-08-317, Received August 21, 2014 Revised November 11, 2014; Accepted November 11, 2014 Ⅰ. 서 론
