摘要

提出了一种优化的基于时隙ALOHA的随机型防碰撞算法——BIS算法。该算法在帧开始前扫描空时隙的位置

并结合标签估算算法实现对帧长的动态调度

最大限度地减少空时隙的时间开销

以实现提高多标签读取效率的目标。仿真结果表明

在不考虑误码的理想情况下

采用该算法的系统效率最高可以达到81%

高于ALOHA算法的理想系统效率

识别速度与一般的时隙ALOHA算法和二进制算法相比有较大幅度的提高。

Abstract

A novel ALOHA-based medium access control（MAC） protocol

BIS

was proposed

in which the time consumption of the empty slots had been largely reduced through empty slot scanning and dynamic frame size adjustment.According to the simulation results

the system efficiency and identification speed of BIS algorithm are efficiently improved

compared to those of the normal ALOHA-based algorithms and tree-based algorithms.
