Smart home architecture based on event-driven DPWS

Abstract

With the advances of electronic information technology and computer network, especially the embedded technology, smart home is no more just a vision but being practical. The interoperability of heterogeneous devices and flexibility of devices' usage are two key problems that challenge the implementation of smart home. To deal with these two issues, this paper proposes an event-driven service oriented architecture using device profile for web services (DPWS). DPWS inherits the advantages of the traditional web services in achieving interoperability without dependence on platform, while improving service discovery and security as well as being optimized for deploying on resource constrained devices. By providing a visual interface for describing a service workflow (SW), the user can easily customize the actions of devices by services composition. Devices automatically cooperate without user's intervention to complete required business logic. This is achieved by fully exploiting the eventing capabilities on DPWS enabled home devices. Finally, a home theater scenario is given to illustrate the event driven mechanism for the SW in the proposed smart home framework.

Investigation of a hierarchical context-aware architecture for rule-based customisation of mobile computing service

“…Thus, a Hierarchical Context-Aware Computing (HCAC) architecture for context gathering, context management, context distribution and service adaptation is proposed towards a holistic solution for context-aware system development. In contrast to the system that is based on specific middleware technologies such as DPWS (Parra et al, 2009;Chen and Zhi, 2011) and OSGi (Gu et al, 2004;Lin et al, 2008), this investigation presents a generalised concept of context-aware system architecture which can be implemented with different techniques. As shown in Figure 4-3, the proposed HCAC architecture gives a clear view of the acquisition, distribution, and utilisation of context data.…”

State of the Art: Embedded Middleware Platform for A Smart Home

“…Therefore, a common solution is to UPnP control point is embedded in a residential gateway to solve this problem [42]. An appliance interface is added into [28], [66], [5], [40], [52], [41], [19], [27] UPnP [48], [42], [31], [71], [17], [24], [49], [40], [52], [35] DPWS [50], [56], [32], [14], [12], [43], [34], [26] an UPnP adapter to translate the UPnP control messages into the private protocol of the appliance. On the other hand, the residential gateway acts as a UPnP control point and any control terminal can be used to control the appliance [42].…”

“…Smart home appliances are implemented based on DPWS [32]. An event-driven SOA using DPWS is proposed in [14]. DPWS inherits the advantages of the traditional web services in achieving interoperability without dependence on platform, while improving service discovery and security as well as being optimized for deploying on resource constrained devices [14].…”

“…Embedded Middleware Platforms SOAP [35], [47], [72], [65] WSDL [21], [85] REST [39], [80], [64] OSGi [40], [53], [83], [81], [29], [54], [68], [49], [69], [38], [76], [46], [14], [77], [19], [11], [13], [60], [82] REST REST is an architecture style for designing networked applications. The idea is that, rather than using complex mechanisms, such as CORBA, RPC or SOAP to connect between machines; simple HTTP is used to make calls between machines [3].…”

“…OSGi is an open specification for the delivery of managed services to networked environments, such as homes and automobiles [14,40,53]. The OSGi service platform consists of the OSGi framework and a set of standard service definitions.…”
