The Impact

Buildings are responsible for a major amount of the annual energy consumption. A detailed recording and evaluation of building data could provide a deeper understanding of building operation schemes and the corresponding performance. This could help building owners and operators to evaluate and better understand the actual situation. Based on this (real-time) data an optimized operation scheme can be designed and implemented for future time steps. Additionally, a more detailed understanding of the impact of previous building systems interactions will be possible. The building automation industry and the related service provider sector are actually providing proprietary solutions for data logging, visualization and energy optimization. Such solutions are regularly integrated into their own specific software of the used proprietary building management solutions. As an alternative, we suggest an Internet of Things (IoT) and web services inspired concept for the implementation of a generic web service for building diagnostics. Our suggestion encompasses a holistic performance evaluation that considers both the energy consumptions and delivered building service. In this contribution, a general design of a web service based solution is presented and the future possibilities for data access from various sources are discussed. Furthermore, details of actually developed and demonstratively implemented software components for data preprocessing are presented. Data processing examples for different types of data are included and highlight the potential of such web-based approaches. Moreover, possibilities for improved building control by the use of web services for operation schedule generation or model predictive control are illustrated and critically debated.

Security Standards

Web services and Service oriented architecture are innovative phase of distributed computing, build on top of the distributed computing models. Web services are being used mostly for the integration business components. One of the key concerns in web services and service oriented architecture is implementation of adequate security. Security issues in SOA are still probing and in spite of an increase in web service research and development, many security challenges remain unanswered. This chapter introduces the vulnerabilities, threats associated with web services and addresses WS-Security standards and countermeasures. Web service protocol is designed to provide connectivity. Not any of these standards of web services contain any inbuilt security aspect of their own. Web Services are exposed to attack from common Internet protocols and in addition to new categories of attacks targeting Web Services in particular. Consequently, the aim of this chapter is to provide review of security mechanism in web services.

The Web

A Web service is a software system designed to support interoperable application-to-application interactions over the Internet. Web services are based on a set of XML standards, such as Web services description language (WSDL), simple object access protocol (SOAP) and universal description, discovery and integration (UDDI). A key role in the Web service architecture is played by UDDI registries, i.e., a structured repository of information that can be queried by clients to find the Web services that better fit their needs. Even if, at the beginning, UDDI has been mainly conceived as a public registry without specific facilities for security, today security issues are becoming more and more crucial, due to the fact that data published in UDDI registries may be highly strategic and sensitive. In this chapter, we focus on authenticity issues, by proposing a method based on Merkle hash trees, which does not require the party managing the UDDI to be trusted wrt authenticity. In the chapter, besides giving all the details of the proposed solution, we show its benefit wrt standard digital signature techniques.

Service provided by one electronic device to the other electronic device or devices is generally called as a web service. It may be a block of code that can be remotely accessed and utilized. In the present IT industry web services are playing a vital role in application development by providing a facility of using the existing modules to make up an application without coding from the scratch. This improves the productivity and reduces the overall project development cost and time. This paper provides the basic information of the components that supports the usage of web service along with the web service architecture. The components that are required for the web service architecture such as SOAP: simple object access protocol: used for establishing connection between components, UDDI (Universal Description, Discovery, and Integration):a registry that stores all the web services and WSDL: web service description language.

As Web services become more and more popular, how to manage multimedia Web services that can be composed as value-added service solutions remains challenging. This paper presents a service-oriented multimedia componentization model to support Quality of Service (QoS)-centered, device-independent multimedia Web services, which seamlessly incorporates cutting-edge technologies relating to Web services. A multimedia Web service is divided into control flow and data flow. Each can be delivered via different infrastructures and channels. Enhancements are proposed to facilitate Simple Object Access Protocol (SOAP) and Composite Capability/Preference Profiles (CC/PP) protocols to improve their flexibility to serve multimedia Web services. We present a set of experiments that show the viability of our service-oriented componentization model that can support efficient delivery and management of multimedia Web services.

Dynamic protocol stacks enable a developer to select a particular protocol profile at bind time where each protocol profile is built from a rich library of protocol modules including UDP, packet loss detection, data encryption, TCP, Multicast among others. Communicating objects can be represented as object graphs that together realise the required behaviour built upon the IP service offered by the host computer. All protocols down to device driver level can be implemented at the user level, providing the maximum potential for configurability. The simple object access protocol (SOAP) is a lightweight remote procedure calling (RPC) protocol for the exchange of structured data in a decentralized environment. SOAP enables programs to run and interoperate with other SOAP applications (called Web services) in a distributed environment. The SOAP protocol is based on extensible markup language (XML) and hypertext transmission protocol (HTTP), which, it is claimed, makes it a language and platform neutral vehicle for RPC over the Internet and through firewalls. This chapter describes a SOAP Web service deployed which enables clients to download protocol stack components as simple MIME attachments.

State Transfer

The interest on Web services has been growing rapidly in these couple of years since their start of use. A web service would be described as a method for exchanging/communicating information between devices over a network. Often, when deciding which service would fit on the architecture design to develop a product, then the question rises which service to use and when?SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) are the two most used protocols to exchange messages, so choosing one over the other has its own advantages and disadvantages. In this paper we have addressed the differences and best practices when to use one over the other.
