As the great prevalence of various Internet Things (IoT) terminals, how to solve problem isolated information among different IoT platforms attracts attention from both academia and industry. It is necessary establish a trusted access system achieve secure authentication collaborative sharing. Therefore, this article proposes distributed based on blockchain edge computing, aiming improve efficiency. This consists physical network layer, layer layer. Through network, an optimized practical...
Blockchain technology is developing rapidly and has been applied in various aspects, among which there are broad prospects Internet of Things (IoT). However, IoT mobile devices restricted communication computation due to mobility portability, so that they can't afford the high computing cost for blockchain mining process. To solve it, free resources displayed on non-mining-devices edge cloud selected construct collaborative network(CMN) execute tasks blockchain. Miners can offload their...
Nowadays, the widely used Internet-of-Things (IoT) mobile devices (MDs) generate huge volumes of data, which need analyzing and extracting accurate information in real time by compute-intensive deep learning (DL) inference tasks. Due to its multilayer structure, neural network (DNN) is appropriate for mobile-edge computing (MEC) environment, DL tasks can be offloaded DNN partitions deployed MEC servers (MECSs) speed-up inference. In this article, we first assume arrival process as Poisson...
Private and public networks sharing resources for Internet of Things (IoT) network through function virtualization (NFV) software-defined networking (SDN) forms a heterogeneous cloud-edge environment. However, the faces trust adaptation issues in resource allocation. To address these two problems, we introduce consortium blockchain deep reinforcement learning (DRL) to construct trusted auto-adjust service chain (SFC) orchestration architecture. In architecture, this article integrates into...
As a mode of processing task request, edge computing paradigm can reduce delay and effectively alleviate network congestion caused by the proliferation Internet things(IoT) devices compared with cloud computing. However, in actual construction network, there are various autonomous subnets adjacent areas, which leads to possibility unbalance server load among during peak period request. In this paper, deep reinforcement learning algorithm is proposed solve complex computation offloading...
As a novel computing technology closer to business ends, edge has become an effective solution for delay sensitive of power Internet Things (IoT) and promotes the application development IoT in smart grids. However, inherent characteristics single node with limited resources may fail meet requirements access ubiquitous businesses massive access. Multiple nodes are needed cooperate each other optimize workload allocation provide lower services. To this end, paper proposes mechanism, orienting...
As Internet-of-Things (IoT) service becomes richer, data sharing among different IoT systems gets popular. The traditional system provides storage and access with the central cloud, which faces serious trust security challenges. To provide a cross-system service, we adopt blockchain to build multicenter management (DM) framework construct trustable environment for sharing. regards problem, attribute-based encryption (ABE) has been applied system, but it still relies on server. Therefore,...
In recent years, the impact of surface heat islands in urban street canyons has become increasingly apparent. However, research on use trees to mitigate remains limited. To address this gap, study combines experiments and simulations analyze cooling effect temperatures under varying timeframes layouts an east–west canyon. The results reveal that temperature road decreases by 10–15 °C, which is 2–4 times greater than south side. Moreover, at 5:00 p.m. afternoon, side 10.3 twice north...
With the fast development of smart cities and 5G, amount mobile data is growing exponentially. The centralized cloud computing mode hard to support continuous exchanging processing information generated by millions Internet-of-Things (IoT) devices. Therefore, mobile-edge (MEC) software-defined networking (SDN) are introduced form a cloud-edge-terminal collaboration network (CETCN) architecture jointly utilize communicational computational resources. Although CETCN brings many benefits, there...
As a new trusted data sharing pattern with privacy protection, the integration mechanism of blockchain and Federated Learning has attracted extensive attention. Generally, this uses technology to supervise original calculation results, which ignores supervision model computing process. Therefore, we introduce concepts sandbox state channel construct paradigm via Blockchain Learning. Under paradigm, use connect And is used create "trusted sandbox" instantiate tasks in trustless edge...
As the future trend, more and vehicles access to Internet of Vehicles, which means that a huge number tasks vehicle terminals need be transformed completed on network. Edge computing makes executed edge nodes near terminal, but some are at relatively idle state these additional resources not utilized, causing great waste resources.
