Abstract

In this Paper, we propose an energy efficient localization technique based on WUSB (Wireless USB) over WBAN (Wireless Body Area Networks) protocol required for Wearable Computer systems. For this purpose, the proposed localization algorithm minimizes power consumption and estimates location without range information. It is executed independently on the basis of WUSB over WBAN protocol at each sensor node comprising peripherals of a wearable computer system. And it minimizes power consumption by estimating locations of sensor nodes with range-free method fast.

본 논문에서는 웨어러블 컴퓨터 시스템을 위한 WUSB over WBAN 프로토콜에서 요구되는 저전력 소모 위치인식기술로서, 거리 정보를 필요로 하지 않는 위치인식알고리즘을 제안한다. 본 논문에서 제안하는 위치 인식알고리즘은 웨어러블 컴퓨터의 주변 장치를 구성하는 WUSB over WBAN 프로토콜 기반 센서노드에서 독립적으로 실행되어, range-free 한 방법을 사용하여, 각 센서노드의 위치를 신속하게 추정함으로써 전력소모를 최소화한다.
