Abstract

The transmitting node in WSN for ITS would be small and operated by battery, and the MCU in the node would be low speed with small sized memory and low power consumption. In this paper, the post-checksum method in which the checksum field is added to the tail of the TCP segment for ITS applications, is proposed to reduce data processing time and power consumption, and so there is no limitation of the transmitting data size.

ITS용 WSN과 같이 작고 건전지로 동작하는 송신 노드에서는 MCU의 성능이 낮고 메모리의 크기도 충분하지 않으며 소비전력을 줄이는 것이 매우 중요하다. 본 논문에서는 이런 환경에서 TCP/IP 통신을 할 때에 사용되는 TCP헤더 옵션 필드와 추가적인 체크섬 필드를 이용하여, 전송하는 데이터의 크기가 메모리의 크기에 제한을 받지 않고, 데이터 처리 시간과 소비전력을 감소시키는 방식이 제안되고 성능이 분석되었다.
