Coexistence of Push Wireless Access with Pull Communication for Content-based Wake-up Radios
arxiv(2024)
摘要
This paper considers energy-efficient connectivity for Internet of Things
(IoT) devices in a coexistence scenario between two distinctive communication
models: pull- and push-based. In pull-based, the base station (BS) decides when
to retrieve a specific type of data from the IoT devices, while in push-based,
the IoT device decides when and which data to transmit. To this end, this paper
advocates introducing the content-based wake-up (CoWu), which enables the BS to
remotely activate only a subset of pull-based nodes equipped with wake-up
receivers, observing the relevant data. In this setup, a BS pulls data with
CoWu at a specific time instance to fulfill its tasks while collecting data
from the nodes operating with a push-based communication model. The resource
allocation plays an important role: longer data collection duration for
pull-based nodes can lead to high retrieval accuracy while decreasing the
probability of data transmission success for push-based nodes, and vice versa.
Numerical results show that CoWu can manage communication requirements for both
pull-based and push-based nodes while realizing the high energy efficiency (up
