실시간 산업환경을 위한 IEEE 802.11기반 가상 폴링 알고리즘 개발
Development of IEEE 802.11 based virtual polling algorithm for real time industrial environments
초록
This paper proposes an effective algorithm, P-DCF(Polling DCF) to satisfy real-time requirements in the industrial environments, based on 802.11 DCF protocols. Theoretical analysis and actual experiments are carried out, which shows that the proposed P-DCF brings several benefits: 1) it reduces the time delay for frame transmission 2)it guarantees bounded upper limit of maximum transmission delay 3) it maintains fairness
