基于IoT-enabled的WBAN信道选择方法

IoT-enabled Channel Selection Approach for WBANs

Mohamad Jaafar Ali, Hassine Moungla, Mohamed Younis, Ahmed Mehaoua

摘要:

微电子技术的最新进展已经实现了无线体域网(WBAN)。然而,无线设备的大规模增长以及将这些设备互连以形成物联网(IoT)的推动对WBAN来说可能是一个挑战;因此,通过仔细的介质访问仲裁来实现强大的通信是必要的。在本文中,我们提出了一种新的协议,使WBAN操作在物联网。基本上,我们利用新兴的蓝牙低功耗技术(BLE),并促进WBAN协调器内的BLE收发器和认知无线电模块(CR)的集成。因此,BLE通过关于在它们附近使用的频率信道的通告来通知WBAN。为了减轻干扰,将TDMA的活动时段扩展为不仅涉及时分多址(TDMA)帧,而且涉及灵活信道选择(FCS)和灵活备份TDMA(FBTDMA)帧。在TDMA帧内的默认信道上经历干扰的WBAN传感器将最终切换到另一干扰减轻信道(IMC)。在CR的帮助下,为WBAN选择IMC,并且每个干扰传感器将被分配(FBTDMA)帧内的时隙以使用这样的IMC进行干扰。

英文摘要:

-Recent advances in microelectronics have enabled the realization of Wireless Body Area Networks (WBANs). However , the massive growth in wireless devices and the push for interconnecting these devices to form an Internet of Things (IoT) can be challenging for WBANs; hence robust communication is necessary through careful medium access arbitration. In this paper, we propose a new protocol to enable WBAN operation within an IoT. Basically, we leverage the emerging Bluetooth Low Energy technology (BLE) and promote the integration of a BLE transceiver and a Cognitive Radio module (CR) within the WBAN coordinator. Accordingly, a BLE informs WBANs through announcements about the frequency channels that are being used in their vicinity. To mitigate interference, the superframe's active period is extended to involve not only a Time Division Multiple Access (TDMA) frame, but also a Flexible Channel Selection (FCS) and a Flexible Backup TDMA (FBTDMA) frames. The WBAN sensors that experience interference on the default channel within the TDMA frame will eventually switch to another Interference Mitigation Channel (IMC). With the help of CR, an IMC is selected for a WBAN and each interfering sensor will be allocated a time-slot within the (FBTDMA) frame to retransmit using such IMC.
