In the IoT (Internet of Things) environment, existing access control schemes for device resources have some problems, such as poor scalability, high latency, security, and dynamics. Combining advantages permissioned blockchain edge computing, an scheme Internet Things based on computing is proposed. By authenticating user’s identity at edge, reliable response time improved. ABAC (Attribute Base...

In this paper, we study a new latency optimization problem for blockchain-based federated learning (BFL) in multi-server edge computing. system model, distributed mobile devices (MDs) communicate with set of servers (ESs) to handle both machine (ML) model training and block mining simultaneously. To assist the ML resource-constrained MDs, develop an offloading strategy that enables MDs transmit...

Achieving an end-to-end low-latency for computations offloading, in Mobile Edge Computing (MEC) systems, is still a critical design problem. This because the offloading of computational tasks via MEC servers entails use uplink (UL) and downlink (DL) radio links that are usually assumed to be coupled single base station (BS). However, heterogeneous networks, new architectural paradigm whereby UL...

Multi-access edge computing (MEC) is one of the emerging key technologies in fifth generation (5G) mobile networks, providing reduced end-to-end latency for applications and load transport network. This paper proposes mechanisms to enhance user privacy MEC within 5G. We consider a basic usage scenario, where accesses an application hosted platform via radio access network operator (MNO). First,...

Merging mobile edge computing with the dense deployment of small cell base stations promises enormous benefits such as a real proximity, ultra-low latency access to cloud functionalities. However, the envisioned integration creates many new challenges and one of the most significant is mobility management, which is becoming a key bottleneck to the overall system performance. Simply applying exi...
