Interoperability for Smart Home Environment Using Web Services
Thinagaran Perumal,Abdul Rahman Ramli,Chui Yew Leong,Shattri Mansor,Khairulmizam Samsudin 보안공학연구지원센터 2008 International Journal of Smart Home Vol.2 No.4
Recent advances in computing and communication technologies paved the growth for applications and devices in smart home environment. A typical smart home is highly characterized by heterogeneity elements that need to perform joint execution of tasks in an efficient manner. Although there are huge growth of services, applications and devices in smart home environment, the interoperability elements still seems ambiguous. Being a distributed architecture, smart home environment needs certain degree of interoperability to manage sub-systems comprising of different platforms. Generally, these sub-systems are developed in isolation and consist of different operating system and tier of services. There is need for a cross-platform interoperability that could make the sub-systems ‘talk’ each other and operate in an interoperable fashion within smart home environment. Web Services seems to be the emerging technology that could lead the way in providing greater interoperability. In this paper we describe the potential of Web Services technology using Simple Object Access Protocol (SOAP) in addressing the interoperability requirements for smart home environment. The SOAP protocol provides data exchange mechanism as well as optimized performance for interoperation among sub-systems residing in smart home environment. The proposed system performance is evaluated to demonstrate a complete, bi-directional real-time management of sub-systems in smart home environment.
IP Based Network Public Address for Intelligent Building Environment
Chui Yew Leong,Abd Rahman Ramli,Thinagaran Perumal 보안공학연구지원센터 2014 International Journal of Smart Home Vol.8 No.6
IP based network public address (PA) is an audio management system that provides high flexibility in reconfiguration, system expansion, and requires much simplified cabling structure. This translates to significant cost saving in installation cost, both labour and material, as it requires less cabling, reduced cable size, conduit size, and trunking size. The network PA works very much similarly to computer networks where packets of data are transmitted from one node to another with each of them having a unique IP address in the network system. The nodes will then only pick up the packets that solely addressed to them. The network PA can also be integrated with other building services or subsystems that are TCP/IP compliant such as the fire alarm management system, CCTV system, and building management system to provide instantaneous voice assisted response and feedback from each system.
