We consider cluster-based routing protocols for energy harvesting wireless sensor networks.
Since the energy harvesting process does not match the real energy demand, sensor nodes …

Cognitive radio is an intelligent and adaptive radio that improves the utilization of the
spectrum by its opportunistic sharing. However, it is inherently vulnerable to primary user …

Due to the limited energy, communication bandwidth and computing ability of edge devices
in Industrial Internet of Things (IIoT) networks, it is incredibly challenging to compress and …

Cellular networks that are traditionally designed for human-type communication (HTC) have
the potential to provide cost effective connectivity to machine-type communication (MTC) …

A novel grant-free random access scheme is proposed to support massive connectivity with
low access delay and overhead for machine-to-machine communication in massive multiple …

In this paper, we put forth a new joint sparse recovery algorithm called signal space
matching pursuit (SSMP). The key idea of the proposed SSMP algorithm is to sequentially …

In this paper, we propose a transmission control scheme for the approximate message
passing (AMP)-based joint user identification and channel estimation in massive …

Sparse vector coding (SVC) is emerging as a key enabler for short-packet ultrareliable and
low-latency communications (URLLCs), since it displays good block error rate (BLER) …

Ultra-reliable low-latency communication (URLLC) constitutes a key service class of the fifth
generation and beyond cellular networks. Notably, designing and supporting URLLC poses …

Channel state information (CSI) feedback in massive MIMO systems is too large due to large
pilot overhead. It is due to the large channel matrix dimension which depends on the …
