Abstract: This research realizes the multi-agent community to handle the rinsing challenges in smart cities by the combined use of multi-fuzzy-agent systems for extracting relevant data from big noisy data, and the multi-agent systems-of-systems for adaptive big data processing. A multi-agent-based large wireless sensor network is used to show the approach used by the multi-fuzzy-agent systems, it exploits sensors as autonomous fuzzy agents that measure the relevance of the collected data and eliminate irrelevant ones. The aim of the multi-agent systems-of-systems is to handle the super velocity of big data flood in an adaptive way, which break down the rigidity of current big data systems that are forced to restart the data analysis process periodically to integrate the newly generated data into the analytical cycle. read more... read less...

Abstract: With the development of cloud computing, more and more applications are posted online to provide services for users. Since user needs can be complex, an individual service will not able to meet the requirement. Web Service Composition composes multiple web services together to fulfil the complicated user requirement. While searching an optimal composition with both functional and non-functional requirements still is a challenging problem that needs to be addressed. QoS-aware web service composition is an NP-hard problem. To solve this problem, we design a system which combines GraphPlan with Fuzzy Control algorithm. Fuzzy Control is employed to generate overall QoS according to user preferences. In the forward phase of Graphplan, less competitive services are pruned according to the overall QoS. In the backward phase, services are selected according to functional goals and their overall QoS. Furthermore, case study and are performed, and the experimental results show that our approach improves the quality of service composition significantly compared with ordinary and Skyline approach. read more... read less...

Abstract: In this paper we consider Green Service Level Agreement (SLA) as a constraint in finding a route for a dynamically received connection request in Wavelength Division Multiplexing (WDM) networks. We show that it is possible to save energy and reduce Greenhouse Gas (GHG) emission while satisfying optical network SLAs. The Integer Linear Programming (ILP) method introduced in this paper has been engineered to be simple and be solved in a timely manner needed for serving a dynamic connection request in control plane of the optical network. The ILP method introduced in this paper for the control plane of Optical WDM networks could also be used for the control plane of Software Defined Networks (SDN) and Software Defined Wide Area Networks. read more... read less...

Abstract: This paper presents a new proposal of a low-cost and low-power wireless smart camera device, designed to be used as an inexpensive smart image acquisition edge node for Internet of Things (IoT). Taking the advantages of the ARM CortexM7 microcontrollers, a high-performance STM32F7 microcontroller is used as a main digital signal processor (DSP) to acquire and transfer images at full rate, keeping the core idle to do real-time image processing. In order to design a very compact, low-cost and low-power wireless image sensor node, the DSP is supported by an embedded 1.3 Mega Pixel CMOS camera sensor and a low consumption 2.4GHz Wi-Fi module. This setup allows a custom build-in image processing algorithm for specific IoT sensing applications or a simply setup as low-cost streaming Motion JPEG (MJPEG) wireless camera node. In this work, both configurations have been tested and analyzed. Results show that the device can acquire and process images simultaneously at a full rate (30 fps) and the MJPEG transmission reaches 7.23 fps with a QVGA resolution. read more... read less...

Abstract: This paper introduces a new resource allocation mechanism for Wavelength Division Multiplexing (WDM) networks. The simple yet effective method introduced in this paper assigns the resources of a dynamically calculated route without needing an optimization solver. By minimizing the number of Lambda conversions at each node using this method, up to 8% more success rate can be achieved compared to assigning the resources using First Fit (FF) with continuity constraint. This method also results in up to 35% less energy usage compared to assigning the resources using First Fit without continuity constraint. The name of N Hop A Kind is after a winning combination of the game of Poker in which a hand with “n of a kind” wins. read more... read less...

Practical Defense-in-depth Solution for Microservice Systems

Abstract: Microservices are a widely deployed pattern for implementing large-scale distributed systems. However, in order to harden the overall system and when crossing datacenter boundaries, the authenticity and confidentiality of microservice calls have to be secured even for internal calls. In practice, however, in many cases no internal security mechanisms are employed mainly due to the increased complexity on backend side. This complexity arises as result of standard security mechanisms like TLS requiring secrets for each involved microservice. Building on previous work [19], in this paper we present a novel communication architecture based on roles that on the one hand guarantees a high level of security and on the other hand remains easy to manage. The approach provides encryption, forward secrecy and protection against replay attacks even for out-of-order communication. read more... read less...

Abstract: Latent Semantic Analysis (LSA) and Latent Dirichlet Allocation(LDA) were used to identify themes in a database of text about railroad equipment accidents maintained by the Federal Railroad Administration in the United States. These text mining techniques use different mechanisms to identify topics. LDA and LSA identified switching accidents, hump yard accidents and grade crossing accidents as major accident type topics. LSA identified accidents with track maintenance equipment as a topic. Both text mining models identified accidents with tractor-trailer highway trucks as a particular problem at grade crossings. It was found that the use of the two techniques was complementary, with more accident topics identified than with the use of a single method read more... read less...

Abstract: Web service composition enables the provision/reusing of existing services in different business processes to satisfy different business requirements without investing in new infrastructure. QoS-aware web service composition seeks to help users find the optimal solution with maximization of users’ satisfaction. A number of approaches based on Communicating Sequential Processes (CSP) have been proposed to model and verify properties of web service composition. However, little work has been done in verifying inputs, outputs and QoS criteria of web service composition. In this paper, we present a framework to model and verify QoS-aware web service composition by Timed CSP. It helps verify whether the service composition can accept inputs, generate outputs, and meet QoS requirements as specified. To do the verification, transformation rules that map QoS-aware web service composition to Timed CSP are defined. In order to explain the framework and transformation rules, we design a case study, where the model of QoSaware web service composition is transformed to the model of process composition in Timed CSP and the program in machine-readable CSP (CSPM). Furthermore, experiments are performed by using the Failure Divergence Refinement (FDR) tool to verify inputs, outputs, and QoS of the service composition. read more... read less...
