面向QoS的蓝牙Piconet网MAC层调度算法的研究与改进

近年来,随着蓝牙技术应用的领域越来越广泛,在ACL链路上传输视频/音频已经成为蓝牙网络的主要业务。这种业务使得在piconet网中的Slave具有了对延迟要求比较高的、同步的CBR业务流,因而能否提出一种高效的MAC层调度算法来有效地控制延迟就显得至关重要。目前,针对蓝牙piconet网MAC层,国内外学者都提出了很多新的算法。大体上可以分为三种:第一,动态地改变Slave的轮询顺序。其中比较典型的算法有:LUQF[9]。第二,动态地为每一个Slave分配带宽。比较典型的算法有:LWRR[9],FEP[9],Adaptive E-limited[9],AQAS[14]。第三,混合算法。即,动态地改变Slave的轮询顺序和动态地分配带宽同时进行。比较典型的算法有:FEP MLQF[9]。然而,这些算法中大部分都是对于传统经典算法,如Round Robin[9], E-limited[9]等做了一些改动,并没有考虑到为实时业务提供QoS服务。本文作者在此研究背景下,提出了一种面向QoS的蓝牙piconet网MAC层调度算法,利用排队论知识对算法性能进行了分析,得出了此算法在理论上的最差性能也会和传统算法中的最优算法:E-Limited算法等同的结论。除此以外,本文作者还使用了网络仿真软件Opnet对新算法进行了性能仿真,得出了新算法的延迟和带宽浪费率曲线,并和本实验组内上届同学的AQAS算法在这两方面进行了性能对比,得出了在以下三种情况下:第一,所有Slave都有相同的非实时业务;第二,虽然都是非实时业务,但业务的到达率不同;第三,Slave中存在实时业务,本文提出的算法的性能都优于AQAS算法的结论。

Science in China(Series F) 2007年第5期50卷 760-770页

作者： WU Qi BI JingPing GUO ZiHua XIONG YongQiang ZHANG Qian LI ZhongCheng Institute of Computing Technology Chinese Academy of Sciences Beijing 100080 China Microsoft Research Asia Beijing 100080 China Lab of Network Science Institute of Computing Technology Chinese Academy of Sciences Beijing 100080 China

Ultra wideband （UWB） network brings both chance and challenge to personal area wireless communications. Compared with other IEEE 802 small range wireless protocols （such as WLAN and Bluetooth）, UWB has both extremely high bandwidth （up to 480 Mbpa） and low radiation. Moreover, the structured MAC layer of UWB is the fundamental difference to WLAN. The top one is that only when two UWB devices belong to the same piconet can they communicate with each other directly, which means that we must jointly consider topology formation and routing when deploying UWB networks because the interaction between routing and topology formation makes separate optimization ineffective. This paper tries to optimize UWB network from a cross-layer point of view. Specifically, given device spatial distribution and traffic requirement, we want to form piconets and determine routing jointly, to maximize the overall throughput. We formulate the problem of joint optimization to mixed-integer programming and give a practical lower bound that is very close to the theoretical upper bound in our simulation. Furthermore, our lower bound is much better than an algorithm that only considers topology formation in UWB networks.

A New Scalable Scatternet Formation for Bluetooth

RESEARCH AND DEVELOPMENT TO THE MOBILE QUALITY INFORMATION MANAGER BASED ON BLUETOOTH TELECOMMUNICATION TECHNOLOGY

2006 the IET International Conference on Wireless Mobile & Multimedia Networks

作者： C.C. Hsu Institute for Information Industry TaipeiTaiwan China

＜正＞In this paper we present a scatternet formation protocol with scalability for dynamic environment. The constructions of scatternet do not need to know the underlying physical topologies and the mobile devices can join in and leave out arbitrarily. If the initial network topology is weakly connected, then our algorithm should guarantee that the resulting topology will be connected. Our algorithm divides the new scatternet into a logical tree structure that simplifies packet routing and scheduling. We also present simulation results that show our algorithm with low formation latency and also generates an efficient topology for forwarding packets.
