摘　　要： 针对HiQ算法存在的缺点,提出一种增强型HiQ读写器MAC协议EHiQ。EHiQ对HiQ算法的结构、即时费用函数等方面进行改进,并引入模拟退火思想,用于平衡学习各个阶段的扩张和探索,缩短学习时间。EHiQ占用的读写器频率-时隙对资源以及频率干扰率略高于HiQ,但收敛时间仅为HiQ的1/3左右。此外,由于系统结构的改进,EHiQ的阻塞率始终保持为零。 Based on HiQ reader anti-collision algorithm,an enhanced algorithm called EHiQ was proposed.EHiQ not only imporves HiQ＇s system structure and cost function,but also imports the concept of simulated anneaning which is applied to balance exploitation and exploration of every phase of learning process and shorten learning time.Simulation shows that resource usage and frequency interference rate of EHiQ are slightly higher than those of HiQ.However,EHiQ＇s convergence time is just one third of HiQ＇s.Moreover,due to the improvement of system structure,EHiQ＇s blocking rate remains zero all the time.
