Abstract

PicoCast is a recently proposed short-range wireless communications technology that supports both low rate sensor/control data and high speed data such as voice and video traffic in the personal space, defined by the user-centric space of radius tens of meters, with one unified protocol. When the users are in the same area, personal spaces defined by each user may overlap. Since these PicoCast piconets may simultaneously operate, mutual interference is unavoidable. It is necessary to investigate the effect of mutual interference on data transmission and to conduct research on minimizing the interference among PicoCast devices. In this paper we analyze the effect of mutual interference between PicoCast piconets based on data throughput using OPNET network simulator. We have implemented the PicoCast protocol and measured the average throughput and packet loss rate.

PicoCast는 개별 사용자를 중심으로 한 반경 수십 미터 범위의 공간("개인 공간")에서 저속의 센서/제어 데이터부터 음성 및 동영상 트래픽의 전송을 단일 프로토콜로써 지원하는 근거리 무선통신 방식으로서 ISO 표준으로 규격화되어 있다. 동일한 공간에 여러 사용자가 있는 경우 사용자 개별적으로 정의한 개인 공간이 중첩되는 경우가 많이 발생할 수 있다. 물리적으로 동일한 공간 내에 여러 PicoCast piconet들이 동시에 작동할 수 있으므로 상호 간섭이 발생하는 것은 피할 수 없다. 이와 같은 환경에서 PicoCast piconet 간의 상호 간섭이 데이터 전송에 얼마나 영향을 미치는지 분석하고, 간섭의 효과를 최소화하기 위한 연구가 필요하다. 본 논문에서는 OPNET 네트워크 시뮬레이터를 이용하여 PicoCast 프로토콜을 구현하고, PicoCast piconet 간의 간섭을 데이터 전송량을 근거로 분석하였다.
