摘要 基于帧时隙ALOHA协议,对ISO18000-6 Type C标准中采用的防冲突算法(Q算法)进行改进。在帧的结束处,改进的Q算法通过检测机制来进行Q值的更新。因为改进的Q算法中每个清点周期的帧大小都会自动地取较优值,所以降低了识别所需要的总时隙数和周期数。仿真结果显示改进的Q算法比TypeC标准中的Q算法更有效。 Based on framed slot ALOHA protocol,the anti-collision algorithm(Q algorithm) of ISO18000-6 Type C is improved.At the end of frame,improved Q algorithm updates Q by means of a detection mechanism.Because the length of frame in every round of improved Q algorithm automatically adaptes the better value,improved Q algorithm reduces the number of slots and rounds of identification.Simulation results show that improved Q algorithm is more efficient than the Q algorithm of Type C protocol.

  • 1Zhang Ping,Ji Yang,Feng Zhiyong (Research Center for Wireless New Technology,Beijing University of Posts and Telecommunications,Beijing 100876,China) The Mobile Ubiquitous Service Environment (MUSE),established through the coordination and integration of mobile telecommunications and ubiquitous network,in the pursuit of Always Best Experience (ABE),represents the major development trend for the next generation mobile wireless network. Research on MUSE will involve the integration of the computing model system,service platform system,operating system and terminal structure system,all of which involve exploration and innovation of a new networking structure,its control and management as well as way of measuring. The change in network resources triggers the change in network computing models. To let readers have a basic understanding of MUSE,this lecture introduces it in four sections. This section focuses on the development and demand analysis of the service platform..Mobile Ubiquitous Service Environment[J].ZTE Communications,2007,5(2):58-60. 被引量:11
