Intelligent Rate Adaptation Based on Improved Simulated Annealing Algorithm

By Lianfen. Huang Chang. Li Zilong. Gao

DOI: https://doi.org/10.5815/ijcnis.2010.01.02, Pub. Date: 8 Nov. 2010

This paper analyzes the PHY layer of IEEE 802.11 standards for a variety of transmission rates, after learning that MAC layer does not provide adaptive approach for rate control. With the study of various adaptive algorithms, the SAARF (Simulated Annealing Auto Rate Fallback) protocol based on simulated annealing algorithm is proposed on rate adaptation in MAC Layer, which can adaptively adjust transmitting rate. Compared with ARF (Auto Rate Fallback) protocol, SAARF can more effectively improve network performance from the simulation results.
