This is accomplished by decoupling the network functions from the physical environment within which they are deployed and converting them into software components that run on top of commodity hardware. Despite its importance, NFV encounters many challenges at the placement, resource management, and adaptation levels. For example, any placement strategy must take into account the minimization of several factors, including those of hardware resource utilization, network bandwidth and latency. Moreover, Virtual Network Functions (VNFs) should continuously be adjusted to keep up with the changes that occur at both the data center and user levels. Over the past few years several efforts have been made to come up with innovative placement, resource management, and readjustment policies. However, a problem arises when these policies exhibit some conflicts and/or redundancies with one another, since the policies are proposed by multiple sources (e.g., service providers, network administrators, NFV-orchestrators and customers). This constitutes a serious problem for the network service as a whole and has several negative impacts such as Service-Level Agreement (SLA) violations and performance degradation. Besides, as conflicts may occur among a set of policies, pairwise detection will not adequate. In this paper, we tackle this problem by defining a conflict and redundancy detection and an automated resolution mechanisms to identify and solve the issues within and between NFV policies. Finally, we integrate a real-time detection component into our solution to provide continuous and comprehensive conflict and redundancy resolution, as new policies are introduced. The experimental results show that the proposed policy detection and resolution tools could rapidly identify, detect and solve conflicts and redundancies among NFV policies and extremely fast than other frameworks. Furthermore, the results show that our solution is efficient even in scenarios that consist of more than 2000 policies. Moreover, our proposed detection mechanisms can detect and solve the conflicts and redundancies for various types of policies such as placement, scaling and migration.</p>","PeriodicalId":50119,"journal":{"name":"Journal of Network and Systems Management","volume":"24 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141501386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The deployment of unmanned aerial vehicles (UAVs) as flying chargers to replenish battery energy is established as an emerging technique, especially in harsh environments. The UAV is also operated by limited battery power and, hence, is also power-constrained. Therefore, the UAV has to timely return to the depot to be fully recharged for the next cycle. The SNs should also be timely recharged before they completely deplete their energy. The design of an efficient charging schedule for the charger-UAV for WRSNs is challenging due to the above-mentioned constraints. Moreover, the problem is non-deterministic polynomial hard (NP-hard). This paper addresses the problem of scheduling the charger-UAV to replenish the energy of SNs in WRSNs. A population-based, nature-inspired algorithm, social group optimization (SGO), is employed to design an efficient charging schedule. The flying energy of the UAV is considered to ensure that the UAV will safely and timely return back to the depot. The fitness function is designed with a novel reward-based approach.

They gather and send a huge amount of data to the fog gateway and then to the cloud due to their use in various real-world IoT applications. This would lead to high data traffic, increased energy consumption, and slow decisions at the fog gateway. Therefore, it is important to reduce the transmitted data to save energy and provide an accurate decision regarding the safety and health of the building’s environment. This paper suggests an energy-aware data transmission approach with decision-making (EDaTAD) for Fog Computing-based IoT applications. It works on two-level nodes in the fog computing-based TI architecture: sensor devices and fog gateways. The EDaTAD implements a Lightweight Redundant Data Removing (LiReDaR) algorithm at the sensor device level to lower the gathered data before sending it to the fog gateway. In the fog gateway, a decision-making model is proposed to provide suitable decisions to the monitoring staff in remote monitoring applications. Finally, it executes a Data Set Redundancy Elimination (DaSeRE) approach to discard the repetitive data sets before sending them to the cloud for archiving and further analysis. EDaTAD outperforms other methods in terms of transmitted data, energy consumption, and data accuracy.

To bridge this gap and bring essential services to rural populations, this paper leverages Unmanned Aerial Vehicles (UAVs). The proposal introduces a UAV-based network architecture and an energy-efficient algorithm to deploy Internet of Things (IoT) applications.

This transition has led to the emergence of multi-access edge computing (MEC) architectures such as distributed micro data center and fog computing. In the MEC environment, network infrastructure is distributed around users, allowing them to access the network nearby and move between different service coverage locations. However, the high mobility of users can significantly affect service orchestration and quality, and even cause service interruption. How to respond to user mobility, dynamically migrate user services, and provide users with a continuous and seamless service experience has become a huge challenge. This paper studies the dynamic migration of service function chain (SFC) caused by user mobility in MEC environments. First, we model the SFC dynamic migration problem in mobile scenarios as an integer programming problem with the goal of optimizing service delay, migration success rate, and migration time. Based on the above model, we propose a deep reinforcement learning-driven SFC adaptive dynamic migration optimization algorithm (DRL-ADMO). DRL-ADMO can perceive the underlying network resources and SFC migration requests, intelligently decide on the migration paths of multiple network functions, and adaptively allocate bandwidth, achieving parallel and seamless SFC migration. Performance evaluation results show that compared with existing algorithms, the proposed algorithm can optimize 7% service delay and 20% migration success rate at the cost of sacrificing a small amount of migration time.</p>","PeriodicalId":50119,"journal":{"name":"Journal of Network and Systems Management","volume":"139 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141061137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It operates based on a budget which limits the percentage of traces to be sampled while adjusting the storage quota of normal and anomalous traces depending on the size of this budget. The sampling process relies on accurately defining clusters of normal and anomalous traces by leveraging the distribution of mass scores, which characterize the probability of observing different traces, obtained from a forest of Half Space Trees (HST). In our experiments, using traces from a cloud data center, SampleHST yields 2.3<span>(times)</span> to 9.5<span>(times)</span> better sampling performance. SampleHST-X further extends the SampleHST approach by incorporating a novel class of Half Space Trees, namely Approximate HST, that uses approximate counters to update the mass scores. These counters significantly reduces the space requirement for HST while the sampling performance remains similar. In addition to this extension, SampleHST-X includes a Family of Graph Spectral Distances (FGSD) based trace characterization component, which, in addition to point anomalies, enables it to sample traces with collective anomalies.
