this paper presents the design, development and evaluation of a novel cloud-based Network Simulator as a Service. It wraps a discrete-event network simulator and deploys it as an elastic service, which can then be used for interactive and batch simulations execution, enhanced with results post-processing and analysis as well as presentation features. It addresses the requirement to rapidly carry out large numbers of network simulations in order to test and validate appropriate and domain specific optimisations in industry, research and education settings. this cloud based service drastically enhances the capabilities of a researcher by allowing arbitrary definition of simulation scenarios along with sets of parameters and commission of large scale simulation executions. It is based on an ensemble of efficient open-source tools, which, when properly coordinated, deliver to the end user a cloud based service that is novel, robust, extendible and extensible. It has been deployed within ESDA Lab (UoP, Greece) where several performance evaluation research scenarios were carried out testing different simulation scheduling schemes in order to evaluate the usefulness of our system and its efficiency under different prioritisation settings. Results demonstrate that, compared to the default general purpose network simulator, the offered cloud-based service significantly enhances end-users capabilities by tailor fitting to their different prioritisation requirements, e.g. favouring interactive users, minimising turnaround times, offering custom resources allocation, etc. In addition to that the offered service effectively hides the peculiarities of the standalone network simulator enabling its use by non-experts and significantly expanding the potential target group of end users.

Network Coordinate System is vulnerable while facing malicious attacks. Traditional works can mitigate the negative influence caused by malicious attacks but the computing processes take too many computation resources. thus the security awareness mechanism of NCS is taken into consideration. through which nodes can know whether it is suffering an attack or not, and decide how to deal withthe situations they faced on. To identify the current security situation, this paper explores an unsupervised learning method that utilizes the spectral radius of the estimation error matrix of the time series. Our method is evaluated on the Vivaldi algorithm against many attack models. In our simulations, malicious nodes perform all known attack methods against NCS. Experiments show that this method can recognize the situation of the networks swiftly with low computation cost.

Today's green computing has to deal with prevalent Cyber-Physical Systems (CPSs), engineered systems that tightly integrate computation and physical components. Green CPS aims to use electronic/computer devices and resources to perform operations as efficiently and eco-friendly as possible. Withthe rise of smart technology combining with Artificial Intelligence Deep Learning (DL) in Internet of things and CPSs, continuing use of these compute intensive CPS software like DL can negatively impact energy resources and environments. Much research has advanced green hardware and physical component development. Our research aims to develop green CPSs by making them energy aware. To do this, we propose an analytical modelling approach to quantifying energy consumption of software artifacts in the CPS. the paper describes the approach through energy consumption modelling of DL in distributed CPS due to the popular deployment of DL in many modern CPSs. However, the approach is general and can be applied to any CPS. the paper illustrates the application of our approach for energy management in scaling and designing smart farming CPS that monitors crop health.
