无线个人网络MAC层仿真平台的建构

在个人网络覆盖完整的前提下,皮克网络之间的串联传输不但扩大了网络的传输范围,也为彼此重叠的皮克网络之间提供了更好的传输环境,也使得超宽带提供的高传输速率得以更有效的利用.但是,目前进行多皮克网(multi-piconet)的研究1],尚没有现成可用的模拟平台.故该论文论述了如何设计一个可行的模拟平台,以达成满足802.15.3 MAC层标准多皮克网络环境的模拟.此平台提供了符合IEEE802.15.3规范的帧格式及传送机制,对不同皮克网间的异步情形进行了相当细致的模拟.对于日后无论在单一皮克网或多皮克网的传输效能研究,都可以作为重要的研究基础.

Emulation platform based on MAC layer of WPANs

Under the precondition of well-covered individual network,Series transmitting between piconet enlarged the network transmitting range,and also provide better transmitting environment for overlapping picnet so as to enable more efficient use of high transmitting velocity provided by ultra wideband.So far there is no simulation plat available for multi-piconet.In this text a practical and feasible mode for simulating plat is presented to fulfill the multi-piconet simulating under 802.15.3 MAC layer criteria.The proposed platform provides standard transmitting mechanism and frame format complying with IEEE802.15.3 regulation,and also be capable of accurate simulation to any asynchronous situation between different piconet.This is a fundamental research for transmitting efficiency for either single or multi piconet.
