Abstract

Sensing, computing and communication are the main features of a wireless sensor network (WSN) which serves a wide range of applications. Despite its versatility and simplicity, it brought up various challenges such as limited storage, power consumption from radio activities, just to mention a few. The distinguishing traits of sensor networks have a direct impact on their protocol design at each layer, especially at the Medium Access Control (MAC) layer since it manages transmission scheduling as well as duty cycling for energy conservation. To maximize energy efficiency of WSNs, a critical analysis of the radio duty cycle of the WSN operating systems were carried out with experimental evaluation. Moreover, we focus on the energy consumption by conducting experimental measurements on different platforms i.e. OpenMote-CC2538 on various operating systems. Results shows that IEEE 802.15.4e Time Synchronized Channel Hopping (TSCH) has great impact on the energy consumption with respect to other radio duty cycles.
WSN操作系统中节能MAC协议的性能评估
传感、计算和通信是无线传感器网络(WSN)的主要特征,具有广泛的应用前景。尽管它的多功能性和简单性,但它带来了各种各样的挑战,如有限的存储,无线电活动的功耗,仅举几例。传感器网络的特性直接影响到其每一层的协议设计,特别是在介质访问控制(MAC)层,因为它管理传输调度和节能的占空比。为了最大限度地提高无线传感器网络的能源效率,对无线传感器网络操作系统的无线电占空比进行了批判性分析,并进行了实验评估。此外,我们还通过在不同平台(即OpenMote-CC2538)上进行不同操作系统上的实验测量来关注能耗。结果表明,IEEE 802.15.4e时间同步信道跳频(TSCH)对其他无线电占空比的能量消耗有很大影响。
