In this paper, we adopt a NOMA-based task offloading and allocation scheme to improve the VEC system. To cope with complex channel conditions, we use NOMA to upload tasks in batches. We first establish the mathematical model, and divide the offloading and allocation of tasks into two ...
NOMA-Based Access andEdge Computing inmmWave Enabled Aerial andGround Integrated Networks doi:10.1007/978-3-031-63705-6_5In contemporary times, there has been a notable surge in the exploration of pervasive coverage, high-speed data connectivity, and edge computing as pivotal components of ...
The proposed NOMA-based system is evaluated against the OFDMA system. The parameters used in the simulation are shown in Table 3. For evaluation, a circular cell layout has been considered with cell area 400m2 having a radius 50 m. We also considered the number of D2D pairs (DTx (max. ...
In the proposed framework, both macro base station and small cell base station can serve multiple users by using NOMA. Since, existing literature mainly focuses on orthogonal multiple access (OMA) based UA schemes, it is necessary to re-design user association (UA) schemes for NOMA. Hence, ...
This paper investigates a framework for integrated sensing and communication (ISAC) based on non-orthogonalmultiple access (NOMA). In this framework, a dual-function base station (BS) utilizes NOMA technology to sendsuperimposed signals to various users, and this superimposed signal also acts on tar...

NOMA-Based Task Offloading and Allocation in Vehicular Edge Computing Networks Vehicular Edge Computing (VEC) is envisioned as a promising approach to process explosive vehicle tasks. In the VEC system, vehicles can choose to upload tasks to nearby edge nodes for processing. This approach requires ...
In this paper, the outage performance analysis for non-orthogonal multiple access based cooperative ambient backscatter communication system is investigated. In this system, the near user, which is equipped with backscatter communication device, acts as a relay node to reflect signals. To guarantee ...
Third, we propose an iterative algorithm to obtain the joint sub-channel and power allocation strategies. Simulations results show that the proposed OFDMA-NOMA scheme performs better than the OFDMA-based scheme. Introduction Due to growing the number of smartphones and tablets users, it is ...
