The Internet of Things (IoT) driven latency-critical applications are deployed on lightweight Micro-Clouds at the network's edge. Renting physical space from geographically distributed colocation datacenters connected via a Wide Area Network (WAN) is a cost-effective way of deploying Micro-Clouds, despite WANs' dynamic communication latency from traffic congestion. However, this deployment approach can limit Micro-Clouds to operate within a soft power budget, as colocation datacenter providers utilize it to add more servers and lower capital costs through oversubscribing power infrastructure. As a result, Micro-Clouds use extreme energy reduction measures like power capping and task throttling to address power overdraw events, where power consumption exceeds soft power budget limits, which reduces the performance of latency-critical applications. We propose a solution where a dynamic power budget can be achieved by adding renewable energy sources to the existing soft power budget without upgrading power delivery systems. To take advantage of this, we propose a dynamic, decentralized task-scheduling algorithm called DEMOTS. DEMOTS effectively utilizes the available dynamic power budget in a WAN with varying degrees of network traffic congestion, thereby avoiding the need for extreme energy reduction measures. We implement DEMOTS on a simulation test-bed. Compared to state-of-the-art baseline using MCOP for decentralized task-scheduling in Micro-Clouds, DEMOTS reduces Power Overdraw Impact up to 19%, Task Latency Increase Impact up to 47%, and Task Schedule Time Impact up to 49%.

This research aims to explore and develop original approaches for improving the scalability and efficiency of distributed network computingsystems. The escalating demand for high-performance computing and the widespread integration of interconnected devices present a critical challenge in optimizing resource allocation and load balancing within distributed networks. The study will investigate cutting-edge algorithms, employ machine learning techniques, and devise adaptive strategies to dynamically distribute computing tasks across network nodes. The primary objective is to enhance system scalability, minimize response times, and maximize resource utilization, contributing significantly to the progression of network technologies in distributedcomputing environments. The research findings are expected to have substantial implications for various applications, including cloud computing, edge computing, and Internet of Things (IoT) ecosystems.

Insider threats present a formidable challenge to cybersecurity, as insiders possess the privileges and information necessary to execute diverse attacks. A comprehensive analysis of user behavior, including behavioral features, sequences, and inter-user relationships, is required for effective insider threat detection. However, few existing methods consider these features in an integrated manner, which could result in high false positives. To further improve the accuracy of insider threat detection, we propose a novel framework for insider threat detection based on a temporal graph convolutional network with data augmentation (referred to as TGCN-DA), which integrates the exploration of structural information among users and simultaneously captures the behavior temporal dependencies. In particular, we introduce an edge predictor to encode user structural information and strengthen intra-class edges among users based on the representation of users' behavior. Additionally, the GCN with temporal feature mechanism is leveraged to learn dynamic changes in users' behavior to capture behavior temporal dependence. Extensive experiments demonstrate that our proposed TGCN-DA outperforms other state-of-the-art methods and achieves higher accuracy in the task of insider threat detection.

As the amount of data and complexity of neural network models continue to grow, distributed training has become increasingly crucial for improving training speed. However, the bottleneck of distributed training is the communication overheads among distributed workers. Recent research has shown that performing in-network aggregation using programmable switches is a good way to accelerate distributed training. However, previous work has only targeted specific neural network models and can only be applied in specified network topologies. Administrators may train different models and train them in different network topologies. In order to generalize the approach of using programmable switches to accelerate distributed training, we propose N4, a programmable intra-switch acceleration framework that supports distributed training of multiple neural networks. N4 also realizes the deployment of distributed workers based on any topology. Our experimental results show that N4 ensures high performance and isolation when training numerous neural networks. N4 outperforms state-of-the-art systems, accelerating training for existing methods by up to 3.4x.
