This paper presents an approach for Web service (WS) composition that enables the automatic adjustment of the composition at run-time to deal with WS execution flaws, e.g., WS unavailability, failure to execute properly or to produce desired results. The WS composition problem is converted into a nondeterministic planning problem which, by its turn, is mapped to SAT. Afterwards, a SAT solver obtains all the possible WS compositions with a maximum length N, which are then fused into a contingency strategy (CS) according to compatibility criteria. Such strategy enables the process execution engine to readily choose the most suitable WS composition to enact, and switch to an alternative composition with minimum adaptation cost in case of any WS execution flaw.

The growing data traffic demand is forcing network operators to deploy more base stations, culminating in dense heterogeneous networks that require a high-connectivity backhaul. This scenario imposes significant challenges for current and future cellular networks, and Software Defined Networking (SDN) has been pointed as an enabling technology to overcome existing limitations. This paper shows how the OpenFlow protocol can be integrated into existing Long Term Evolution (LTE) networks to provide the required Quality of Service (QoS) in the network infrastructure. Three OpenFlow-based mechanisms are proposed: a traffic routing, an admission control function, and a traffic coexistence mechanism. Together, they can effectively control the bandwidth usage in the backhaul infrastructure, improving the QoS and ensuring a better user experience. Simulations were performed to validate the proposed mechanisms and highlight the benefits that can be achieved with the flexibility offered by the SDN technology.

The advent of Cloud computing is changing the way of conceiving information and communication systems in different application fields including Biotechnology. In this context, an emerging research field is Next-Generation Sequencing (NGS) that includes several recent technologies allowing sequencing DNA and that have revolutionized the study of genomics and molecular biology. These cutting-edge sequencing systems produce big datasets that require significant scalable computing resources. In this paper, we analyse and classify the major current NGS Cloud-based solutions adopted in scientific laboratories according to different Cloud service levels. Moreover, by means of a taxonomy, we discuss the challenges and advantages of possible future NGS Cloud-based systems.

Recent technological advances have accelerated the design and deployment of kinds of secure applications on smartphones. Although users can access and handle their data flexibly and stably with mobile devices, not only computing devices, it poses security challenges of a new dimension that users disclose lots of sensitive data and privacy information over open devices and networks as well. Thus, more and more malwares are emerging to compromise mobile OS and steal sensitive data from these applications. In this paper, we propose a mobile payment framework TrustPAY on TrustZone security enhanced platform, which can ensure payment transactions security and realize privacy friendly payment. We have implemented a prototype system on a simulation environment by using ARM FastModel and Open Virtualization software stack for ARM TrustZone, and presented our implementation on a real development board by using ARM CoreTile Express A9×4. Our experiment evaluation and security analysis prove that our scheme can effectively meet the security requirements of a practical m-payment with acceptable performance. Furthermore, TrustPAY is also flexible to support kinds of secure applications requiring to privacy protection.

Visualization means the use of Information Visualization (InfoVis) techniques to augment human cognitive capacity to support users tasks more efficiently. According to the current literature, visualization is a relevant requirement to support the management of Software-Defined Networking (SDN). For example, visualization can help network administrators in everyday tasks such as in the identification of traffic patterns, or in the implementation and test of new networking services. However, in most cases, network administrators are unskilled on InfoVis, which makes them naturally reluctant in the use of visualizations. Also, building up visualizations from scratch can spend a significant amount of effort, which directly impacts on the increase of cost and the decrease of administrators' productivity. Thus, in this paper, we introduce a reuse-based approach to facilitating the employment of visualizations in the SDN context with the focus on improving productivity and reduce costs. We developed a prototype to evaluate and demonstrate the feasibility of our approach. The obtained results to one of the usage scenarios show, for example, that our solution can decrease in 264 hours the administrators' workload (i.e., around U$ 9,976.56) when employing visualizations in daily tasks.

The number and capabilities of IoT devices will exponentially grow over the next years. Together with the pervasive diffusion of smart personal mobile devices this opens up unprecedented opportunities for contextualised services provided to mobile users, based on their current interests and behaviours. In addition, most of these services will be content-centric rather than host-centric. Cloud computing and Information-Centric Networking (ICN) are therefore two key technologies in this perspective. In both cases, solutions are typically designed for global Internet platforms, while mobile nodes are seen as edge devices from which data are fetched and sent back through pervasive wireless networks (typically, LTE). However, it is questionable whether such an approach will work as expected, e.g., due to data privacy concerns and expected bandwidth shortage of even last-generation cellular networks. In this paper we present a general framework where global cloud and ICN platforms are complemented in a totally synergic way by local clouds formed at the edge of the network by mobile devices, where service provisioning and data management functionalities are offloaded whenever possible (and appropriate). This results in a multi-layer, content- and service-centric approach to IoT data management and service provisioning. We then present performance evaluation results from applying this framework to a specific case where data-centric services are jointly provided by edge devices and by a global cloud platform. Results show that this approach is very promising, as it is able to drastically cut the related cellular-network traffic, and, at the same time, improve the effectiveness of service provisioning to users.

Stream-based data processing systems, such as Complex Event Processing or data stream mining systems, may be composed of several components which may be implemented in various programming languages. In distributed scenarios, computer networks typically represent important bottlenecks. However, the performance of data exchange in local contexts may be as important as the performance of data exchange via computer networks. Local programming language barriers may represent important bottlenecks for components that are located on the same computer system. In distributed scenarios, it may be beneficial to relocate components on a single physical host for exploiting the higher local data throughput. The properties of stream-based systems pose challenges like high throughput requirements but also open up optimization potential such as leveraging batched transfers. We performed an experimental analysis of ways for bridging local programming language barriers using the examples of C, Java, and Python and analyzed the impact of batched forwarding. While local data exchange can be expected to offer a higher throughput than exchange across networks, our results show that batch forwarding can increase the local throughput by factors of up to 47.6 and we measured net throughputs up to 39.5 Gbps.

Mobile communication and data services face a rapid growth and result in an ever increasing demand of bandwidth. As alternative to investing in the infrastructure by splitting cells down to nano or pico scale, this paper introduces and evaluates a concept for traffic data offloading to ad-hoc communication in terms of device-to-device communication. The idea is to combine infrastructure-aided route discovery with local mobile ad-hoc network communication to handle traffic with a local focus, i.e. intra-cell or neighbouring-cell traffic. We analyse the concept in terms of latencies and packet delivery ratio by using Omnet++ simulations. We demonstrate that the approach comes with low overhead and allows for an efficient distribution of traffic depending on the expected communication range.

In cognitive radio networks, cognitive users are allowed to use the licensed portions of spectrum, as long as no harmful interference affects the primary (licensed) users. Towards achieving this goal, spectrum sensing is an essential process to determine spectrum access opportunities for the cognitive users. In wide spectrum applications, it is recommended to distribute the sensing task of the required bands among the cognitive nodes to reduce the sensing process overhead. This paper presents a fuzzy inference based scheme for distributing the sensing task among cognitive nodes. This scheme is proven, via simulations, to reduce the overall probability of sensing error compared to two other cooperative sensing mechanisms.

This work presents algorithms for the design phase of flexible grid optical networks considering the impact of in-band channel crosstalk. Due to crosstalk-induced interactions among different connections, malicious high-power signals can potentially spread widely in the network. Moreover, crosstalk interactions also affect the signal quality of transmission. To this end, it is necessary to plan an optical network in a way that the crosstalk effect is minimized. In this work, a novel Routing and Spectrum Allocation (RSA) optimization algorithm based on Integer Linear Programming (ILP) is proposed in order to minimize the impact of the in-band crosstalk effect in flexible grid optical networks through proper utilization of the resources. Additionally, a heuristic algorithm is proposed to handle larger network instances. Performance results indicate that the proposed algorithms perform close to the First Fit spectrum allocation algorithm in terms of total spectrum utilization of the network, while at the same time minimizing the total number of in-band lightpath interactions.
