Abstract

IEEE802.15.4 that is a standard for sensor networks is mainly used the wireless personal area networks such as ZigBee networks and it features low-power, low-speed data communication. However, recently research for interworking sensor network based voice communication and Session Initiation Protocol (SIP) for long-range, multi-user support has been actively conducted. In this paper, we designed a integrated base station based existing systems for interworking sensor networks based voice communication and SIP. We measured number of packet and delay according to increase the number of users to evaluate the performance of designed Base Station.

센서 네트워크를 위한 표준인 IEEE802.15.4는 저전력, 저속 데이터 통신이 특징으로 주로 ZigBee 네트워크와 같은 Wireless Personal Area Network (WPAN)를 구성하기 위해 사용하고 있다. 그러나 최근 센서 네트워크 기반의 음성통신과 Session Initiation Protocol (SIP)를 연동하여 장거리 및 대규모 사용자를 지원하기 위한 연구가 활발히 진행되고 있다. 본 논문에서는 센서 네트워크 기반의 음성통신과 SIP를 연동하여 다수 사용자 지원하고 기존 시스템을 하나의 통합 Base Station으로 설계하였다. 또한, 설계한 Base Station의 성능을 평가하기 위하여 사용자수 증가에 따른 Packet 수와 Delay를 측정하였다.
