Abstract

Research on media access control (MAC) scheme for Wireless Sensor Network (WSN) has been mainly focused on energy efficiency improvement, while interest on latency is relatively weak. However, end-to-end latency could be a critical limitation specifically in the multi-hop network such as wireless multimedia sensor networks. In this paper we propose a media access control scheme with distributed transmission power control to Improve end-to-end transmission latency as well as reduce power consumption in multi-hop wireless sensor networks. According to the simulation results, the proposed scheme is turned out to be an energy efficient scheme with improved end-to-end transmission latency.

응용분야를 계속 확장해가고 있는 무선 센서네트워크에서 매체접근제어 (MAC)에 관한 연구는 주로 에너지 효율을 높이는데 집중되어왔으며 전송지연(Latency)에 관한 연구는 상대적으로 적다. 그러나 센서 네트워크의 특성상 다중 홉(multi-hop) 전송이 빈번하게 일어나는 환경에서 종단 간 전송지연은 특히 시간 종속적인 응용분야에서는 중요한 성능상 제약이 될 수 있다. 본 논문에서는 분산적인 전송전력제어방식을 이용하여 다중 링크를 동시에 개설할 수 있도록 함으로써 센서네트워크의 전송 전력을 줄임과 동시에 네트워크의 공간 활용도를 향상시키고 전송지연시간을 개선 할 수 있는 매체접근제어(MAC) 방식을 제안하였다. 시뮬레이션을 통한 성능 검증 결과 제안하는 방식인 TPCS-MAC은 센서노드의 전력소모를 줄임과 동시에 특히 다중 홉(multi-hop) 센서네트워크에서 발생하는 종단 간 지연 (end-to-end latency) 문제를 개선하는 것으로 판명되었다.
