Wake-up transceiver protocol for power line communications

Abstract

This paper presents a wake-up transceiver system based on narrowband power line communications (NB-PLC). An energy-pattern based sequence detection algorithm is proposed for the recognition of a wake-up sequence by the receiver. The method is characterized by low computational complexity and does not require channel parameter estimation and adaption. Furthermore, a blind packet repetition technique is introduced that accomplishes periodic impulsive noise avoidance. A realistic and straightforward narrowband power line channel model is presented and the proposed wake-up protocol is verified against it in terms of Monte-Carlo simulations. It is demonstrated, that the method leads to significant improvements compared to state of the art low-complexity PLC systems in typical NB-PLC channels

Ultra Low Power Wake-Up Radios: A Hardware and Networking Survey

“…Among these, power line communications (PLC) is a straightforward non-wireless choice. Several wake-up mechanisms that share similar medium, requirements, and protocols have been already proposed [176], [177].…”

“…1) Matching Prototypes: Micro-grid communication often includes heterogeneous technologies. Some of the prototypes that suit smart grid requirements are presented in [36], [67], and [178], while non-RF wakeup circuits such as those in [176] and [177] also exists even if with features tailored for cable communication [177].…”

“…In these cases, protocols such as PTW, AWD-MAC, and STEM-B are suitable candidates. For the wake-up mechanism developed over PLC (on cables), the protocol needs tight synchronization and the one proposed in [176] is suitable for the purpose.…”
