Abstract-This paper proposes a Network Intrusion Detection System (NIDS) embedded in an Smart Sensor inspired device, under a Service Oriented Architecture (SOA) approach, able to operate independently as an anomaly-based NIDS or integrated, transparently, in a Distributed Intrusion Detection System (DIDS). The proposal is innovative, because it combines the advantages of Smart Sensor approach and the subsequent offering of the NIDS functionality as a service with the SOA use in order to achieve their integration with other DIDS components. The main goal of the work is to reduce the huge volume of management tasks inherent to this type of network services, as well as facilitating the design of DIDS whose managing complexity could be restricted within well defined margins. The work also addresses the construction of a physical sensor prototype. This prototype was used to carry out the tests that has demonstrated the proposal's validity, providing detection and performance ratios similar to those of existing IDS, but with the advantage of a zeromaintenance approach.
The web services framework is specially conceived for integrating, in an easy way, different internet services from different providers. Web services have been widely adopted in business applications using PC-based servers as their main implementation platform. However, the nowadays growing computational and communication power of the FPGA devices allows its implementation taking advantage of the special features that those platforms offer. In this work we propose a reconfigurable architecture to support web services that reduces the cost and maintenance of the system and increases the security and robustness of the service. The feasibility of our approach is demonstrated by developing a specific service, called WoLI, which allows the remote wake up of network nodes over internet. The prototype has been proved and tested in a real environment where the service is accessible from any client able to support standard communication with a web server.
-This paper presents an approach for designing robots and robotic systems based on the application of models, architectures, techniques and tools that have contributed valid solutions in other areas, such as e-business. Before applying these solutions, the physical elements that make up a robotic system are subjected to a normalization process in order to characterize their functional contributions. In this way, the conceptual model and the technical architecture of the service-oriented architecture robotic system is established. The paper also includes a simple implementation enabling the proposal to be validated, together with the main conclusions reached and future lines of study.
Abstract-In this paper we introduce a System on Chip (SoC) designed to run a particular Web Service (WS) in an Application-Specific Integrated Circuit (ASIC). The system has been designed devoid of processor and software and conceived as a hardware pattern for a trouble-free design of network services offered as WS in Service-Oriented Architecture (SOA). Therefore, the chip is not only able to act as SOAP Service Provider but, it is also capable of registering the service on its own in an external Broker Server using the UDDI Standard publication protocol as well. This proposal has been named Web Service on Chip (WSoC) and its main goal of is to implement more cost effective and zero-management SOA network devices. To validate this approach, a prototypical device has been developed using FPGA technology. The particular network service selected has been WoL over Internet thus allowing any WS Client to wake up any network node compatible with WoL technology. A full SOA scenario also has been developed to test the prototype functionalities and show the proposal validity.
Abstract-Wireless Smart Sensor Networks (WSSN) offers a new paradigm regards to the way that the traditional monitoring systems have been designed, all this happens due to the impactgenerating by technology in society. The deployment of Information and Communication Technologies or ICT allow us now rely with small devices that are able to integrate into a "simple element" the potential of computing, communication and monitoring systems and from here starts to move to these minidevices, the ability of intelligence that ensure the deployment of new systems focused in environmental monitoring. In this paper we present a survey of technologies employed to wireless smart sensor networks, their management systems as well as their trends and finally we presents the design and implementation of an application for monitoring environmental variables using the WSSN and virtual instrumentation on Smartphone.
