Abstract

As noted in the various USN service implementations including those in U-City, the reliable data transmission has become the essential component as the USN services are getting more various. The assurance of the reliability is needed sometimes prior to other QoS specifications of the USN services. The efficiency would become more important as well in USNs because the efficient and reliable delivery of a packet could be consequently linked to the energy saving. This paper is intended to provide the performance comparisons of data delivery schemes in USNs.

유시티를 비롯하여 여러 시범사업에서 나타나듯이 유비쿼터스 네트워크상에서 제공되는 서비스가 다양해질수록 안정적인 데이터 전송은 필수적인 요건이 되었다. 이렇듯 신뢰성은 서비스에서 요구하는 그 외의 서비스 품질상의 요구사항들에 앞서서 해결되어야 하는 가장 기본적인 사항이 되었다. 또한 유비쿼터스 센서 네트워크에서 가장 중요시 생각하는 저전력 통신의 근간을 지키기 위해서도 효율적이며 안정적인 데이터 전송은 기본적으로 필요한 사안이 되었는데 근본적으로 효율적이고 안정적인 데이터의 전달이 에너지 절감에도 도움이 되기 때문이다. 이에 본 논문에서는 유비궈터스 센서 네트워크에서의 데이터 전송 방법에 따른 효율성과 안정성을 성능 분석을 통해서 비교해 보고자 한다.
