大规模无线传感器网络控制信道和数据信道的分配

Allocation of control and data channels for Large-Scale Wireless Sensor Networks

Jamila Ben Slimane, Ye-Qiong Song, Anis Koubâa, Mounir Frikha

摘要:

IEEE 802.15.4和802.15.4a标准都允许动态信道分配和使用在其物理层可用的多个信道,但是其MAC协议仅被设计用于单个信道。此外,传感器的收发器(如CC 2420)提供多个通道,如[1]、[2]和[3]所示,CC 2420收发器的通道切换延迟仅约为200 $μ$ s。为了提高能源效率和缩短端到端的延迟,我们提出,在这份报告中,频谱效率的频率分配方案,能够静态分配控制信道和动态重用数据信道的个人区域网络(PAN)内的一个大规模的基于UWB技术的无线传感器网络。

英文摘要:

Both IEEE 802.15.4 and 802.15.4a standards allow for dynamic channel allocation and use of multiple channels available at their physical layers but its MAC protocols are designed only for single channel. Also, sensor's transceivers such as CC2420 provide multiple channels and as shown in [1], [2] and [3] channel switch latency of CC2420 transceiver is just about 200$μ$s. In order to enhance both energy efficiency and to shorten end to end delay, we propose, in this report, a spectrum-efficient frequency allocation schemes that are able to statically assign control channels and dynamically reuse data channels for Personal Area Networks (PANs) inside a Large-Scale WSN based on UWB technology.
