Abstract

This paper presents an efficient user-cooperation protocol associated with cyclic coding for WSNs (Wireless Sensor Networks) using LEACH(Low-Energy Adaptive Clustering Hierarchy). Since the proposed user-cooperation requires no CSI(Channel State Information) at both transmitter and receiver, and encoding and decoding of cyclic codes are simple, the processing complexity of sensor nodes is significantly reduced. Simulation results reveal such a combination can save the network energy up to 10dB over single-hop transmission at BER of $10^{-4}$.

본 논문에서는 LEACH (Low-Energy Adaptive Hierarchy)를 사용한 무선센서네트워크에서 순환 부호를 사용하여 효율적인 사용자 협력 프로토콜을 제안한다. 제안한 시스템에서는 송수신단 간에 채널 상태 정보가 필요하지 않기 때문에 순환 부호를 부호화하는 것과 복호하는 것은 단순해지고 센서 노드의 처리 복잡도가 크게 줄어들 수 있다. 모의실험 결과를 통해서 순환 부호를 적용한 센서 네트워크는 단일 홉 전송의 비트오율 $10^{-4}$에서 네트워크 수명이 10dB까지 절약되는 것을 알 수 있었다.
