This paper investigates the covert communication of cooperative non-orthogonal multiple access (NOMA) systems, where near user serves as a decode-and-forward (DF) relay and far receives information from both source user. To improve covertness performance, jamming power randomness are adopted. Specifically, we derive detection error probability (DEP) Willie minimum (MDEP) at optimal decision thr...

With the rapid development of mobile robots, they have begun to be widely used in industrial manufacturing, logistics scheduling, intelligent medical, and other fields. For large-scale task space, communication between multiagents is key affect cooperation productivity, agents can coordinate more effectively with help dynamic communication. However, traditional mechanism uses simple message agg...

With the rapid evolution of Internet things (IoT), many edge devices require simultaneous connection in 5G communication era. To afford massive data IoT devices, multiple input output non-orthogonal access (MIMO-NOMA) method has been considered as a promising technology. However, there are numerous drawbacks due to error propagation and inter-user interferences. Therefore, proposed scheme aims ...

In this paper we first define a mathematical model of the “plant” for the cooperative control problem for multiple uninhabited autonomous vehicles (UAVs). This includes a representation for the vehicles, environment, and communication network. Next, s e define an approach to cooperative control that uses local UAV task planning and multi-UAV coordination via task load balancing over the communi...

Although cooperative communication has been proposed at the physical layer to address multi-path fading effects, how physical layer gains with cooperative communication can translate to tangible performance benefits in end-to-end flows remains to be an open problem. This paper represents one step forward towards a deeper understanding of the interplay between end-to-end throughput and physical ...

Wireless sensor networks (WSN) are presented as proper solution for wildfire monitoring. However, this application requires a design of WSN taking into account the network lifetime and the shadowing effect generated by the trees in the forest environment. Cooperative communication is a promising solution for WSN which uses, at each hop, the resources of multiple nodes to transmit its data. Thus...
