Data-Driven Resource Allocation for Deep Learning in IoT Networks

Chang-Jae Chun;Cheol Jeong

IEEE Internet of Things Journal
Year: 2024 | Volume: 11, Issue: 2 | Journal Article |
Cited by: Papers (3)
We consider an Internet of Things (IoT) network, where a large amount of sensor data is transmitted from wireless IoT devices to a central server for the classification of system behaviors. When the number of IoT devices and their sensors is very large, the redundancy in the collected data at the server can also be very high due to the high correlation between the data. By compressing the sensor d...Show More

Cited by: Papers (10)
We consider heterogeneous network (HetNet) systems comprising of two different types of base-stations (BSs): macro and small BSs. In the previous studies for HetNet, it is observed that the distribution of signal to interference plus noise ratio (SINR) is independent of the BS density. This implies that network throughput increases linearly with the number of BSs. In this paper, however, we have i...Show More
