In future, lightpaths will be dynamically provided to users by the use of GMPLS but lightpath networks may be overlaid to the users. When the users want to find idle wavelengths by probing for lightpath provisioning, they may not be able to obtain information about all the idle wavelengths along the route in the overlaid lightpath net-work. They are only allowed to include a limited number of wavelengths for probing. In order to avoid wavelength contention and reduce blocking probability, we present a. method for performance estimation of overlaid lightpath networks from a user side. In this method, we try to find wavelengths that are likely to be idle. This is done by the wavelength based rank accounting for each pair of a source and a destination. Rank is calculated each time a lightpath is provisioned at a pair regardless of the success or failure of the provisioning. We demonstrate that the method of estimation is effective through simulation experiments and also present an initial implementation of a lightpath-provisioning system that uses our performance estimation method based on the GMPLS RSVP-TE mechanism.

High-rate distributed denial of service (HDDoS) flooding attacks pose as a major threat to the internet. Most present solutions based on machine learning approach are inept for detecting the attacks in real time due to high processing overhead. In this paper, we present a defense solution referred to as DyProSD that combines both the merits of feature-based and statistical approach to handle HDDoS flooding attacks. The statistical module marks the suspicious traffic and forwards to an ensemble of classifiers for ascertaining the traffic as malicious or normal. Our method filters the attack traffic protocol specifically by allocating various protocol specific filter engines dynamically. As and when DDoS attack occurs and the load of a filter engine reaches beyond its capable limit, a new filter engine is recruited dynamically from the idle resource pool for filtering, thus guaranteeing the quality of service for legitimate users concurrently. We establish the effectiveness of DyProSD through several experimental analysis and real-world dataset experiments and the results indicate enough confidence in favour of our solution.

As one of the most popular big data processing engines, Apache Storm is used in many fields. However, the performance of the traditional Storm framework can no longer meet current needs due to explosive growth of data in internet of Things. In this article, FPGA is integrated as the computing node into the Strom framework, and two optimization methods are proposed for the framework to improve system performance. We use matrix multiplication to evaluate the optimized system. When the matrix size is 256×256, the FPGA-based Storm system has a maximum reduction of 37.10% in the average processing delay of tuples compared to the native Storm system. When the computing resources of the FPGA are large enough, the matrix size of the optimal optimization rate will also increase by increasing the parameter setting of the expansion degree. © 2022 IEEE.

The emergence of content delivery, networks (CDN) has helped improve the efficiency, of delivering streaming media. In this paper, we argue with evidence that the edge delivery, paradigm behind current CDNs cannot scale up to delivering high-quality broadband video content such as DVD movies. This is because there are no sufficient and affordable bandwidth and quality, of service (QoS) on the last mile. Additionally, it is difficult to scale up edge delivery, with increasing number of users and aggregate bandwidth demand in services such as video-on-demand. We describe a new architec-ture that extends the current CDN design with a second tier of surrogate servers. These second-tier surrogate servers, called leaf servers are placed inside local area networks and networked homes with broadband internet connection. High scalability and QoS can be achieved because media content is served to clients by massively distributed leaf servers over the last foot.

There has been a growing spate of Cyber attacks targeted at different corporate enterprises and systems across the globe. The scope of these attacks spans from small scale (grid and control system manipulation, domestic meter cyber hacking etc) to large scale distributed denial of service attacks (DDoSA) in enterprise networks. The effect of hacking on control systems through distributed control systems (DCS) using communication protocols on vulnerable home area networks (HANs) and neighborhood area networks (NANs) is terrifying. To meet the current security requirements, a new security network is proposed called Smart grid convoluted network (SGCN). With SGCN, the basic activities of data processing, monitoring and query requests are implemented outside the grid using Fog computing layer-3 devices (gatekeepers). A cyber monitor agent that leverages a reliable end-to end-communication network to secure the systems components on the grid is employed. Cyber attacks which affects the computational requirements of SG applications is mitigated by using a Fourier predictive cyber monitor (FPCM). The network uses flexible resources with loopback services shared across the network. Serial parallelism and efficient bandwidth provisioning are used by the locally supported Fog nodes within the SG cloud space. For services differentiation, SGCN employed secure communication between its various micro-grids as well as its metering front-ends. With the simulated traffic payload extraction trend (STPET), SGCN promises hard time for hackers and malicious malwares. While the work guarantees security for SGs, reliability is still an open issue due to the complexity of SG architecture. In conclusion, the future of the Cyber security in SGs must employ the concept of internet of Everything (IoE), Malware predictive analytics and Fog layers on existing SG prototypes for optimal security benefits.

computing, internet, digital devices, smart devices, and other technologies were leading to a new terminology known as cloud of things (CoT). Cloud of Things is a powerful technology used to analyze and store massive data from thousands of distributed devices (smartphones, vehicles, home appliances, sensors, etc.). Further, Cloud of Things integrated two concepts, internet of Things and Cloud computing. There are many issues in cloud computing that have been widely studied, such as scheduling. On the other hand, a few issues have been studied in Cloud of Things. The objective of this paper is to discuss and classify the scheduling issues in Cloud of Things. Researchers have developed algorithms for different environments such as heterogeneous/homogeneous clusters, cloud computing, and large-scale community grids. By reviewing and considering many of these articles, we provided an overview for reuse these state-of-the-art algorithms in Cloud of Things environments. In addition, this paper provides researchers with ideas and platform for finding open research and exploring Cloud of Things issues. © 2023 IEEE.

A prototype of an express risk assessment system is proposed and implemented as a combination of a distributed simulator and a web interface. A case of aerosol dispersion in an urban environment is investigated. Fast response of the system is achieved by replacing complex 3D simulations with information retrieval from aerosol dispersion database. The database is created by extensive simulations of different aerosol dispersion scenarios. Cluster or grid computing environments are most suitable for these type of simulations. The reduction of system response from a few days to several seconds can be achieved compared to real-time 3D simulations.
