Secure Short-Packet Communications for Mission-Critical IoT Applications

IEEE Transactions on Wireless Communications, 2019
In pervasive Internet of Things (IoT) applications, the use of short packets is expected to meet the stringent latency requirement in ultra-reliable low-latency communications; however, the incurred security issues and the impact of finite blocklength coding on the physical-layer security have not been well understood.

Short-Packet Communications in Non-Orthogonal Multiple Access Systems

CoRR, 2017
This work introduces, for the first time, non-orthogonal multiple access (NOMA) into short-packet communications to achieve low latency in wireless networks. Specifically, we address the optimization of transmission rates and power allocation to maximize the effective throughput of the user with a higher channel gain while guaranteeing the other user ...
