Abstract

WSN gateway which runs transmission between WSN (Wireless Sensor Network) based on IEEE 802.15.4 and PN (Public Network) based on TCP/IP belongs to core technology of application based on two network. Because WSN Gateway receives various kinds of packet from many sensor nodes in an uncertain time as well as uses hardware's performance enough, it has high level of complexity about software and it is hard to be implemented. To solve these problems, this paper suggests both efficient event detection scheme for identify packet and implementation unit of protocol called 'Transaction'. The results of applying the proposed network framework, complexity of software reduces. And we provide software development environments of reflect various performance requirements.

IEEE 802.15.4 기반의 WSN(Wireless Sensor Network)과 TCP/IP기반의 PN(Public Network)의 중계를 담당하는 WSN Gateway는 이 두 개의 네트워크를 기반으로 하는 핵심 기술에 속한다. WSN Gateway는 하드웨어에 대한 성능을 충분히 활용하면서, 다수의 센서 노드로부터 다양한 종류의 패킷을 불특정 시간에 수신해야 하기 때문에 소프트웨어에 대한 복잡성이 높고 구현이 난해하다. 이러한 문제들을 해결하기 위해, 이 논문에서는 패킷을 식별하는 효율적인 이벤트 검출 구조와, '트랜잭션'이라는 프로토콜의 구현 단위를 제안한다. 제안한 네트워크 프레임워크를 적용한 결과, 소프트웨어의 복잡성을 낮출 수 있었다. 또한, 다양한 성능 요구 사항을 반영할 수 있는 유연한 소프트웨어 구현 환경을 제공하였다.
