Middleware in Internet of Things ecosystem plays an important role. Its role is to hide the complexity of connected devices and to provide services to domain-oriented applications that ease the development and support of these applications. Middleware should be able to work with the devices using different protocols, data models and terms. In this paper we describe a middleware, called SemIoT Platform,...
This paper presents the basic data flow in a wireless sensor network based on the current literature of the area. The first step is to study exactly how information and different data move in a system like this. Various frameworks have been proposed to represent data move from one layer to another, in order to reach the end-user. After introducing the basic parts of a sensor network in section 1,...
Heterogeneous network infrastructures have always been part of the public Internet as well as production systems in enterprise and industrial environments. The coexistence of multiple communication technologies and systems from multiple vendors still represents management cost and reliability challenges mainly due to the lack of interoperability at the network management plane. In this paper, we outline...
To address the problem of service composition in pervasive computing, and to provide the IGRS ubiquitous devices the abilities of inter-operation and cooperation, we design the UDIO, a middleware of dynamic service composition based on IGRS protocol. In this paper, the system architecture of UIDO, as well as a matrix-based path-finding algorithm for service composition, are introduced which prove...
As the Home Area Network (HAN) evolves, there is an increase in both the number and diversity of device deployment. This includes embedded devices whose resource constraints do not permit the efficient performance of high level middleware functionality. We herein present the functionality and knowledge representations required to enable such “simpleware” devices to be dynamically represented by proxy...
The rapid development of information technology offers people a broad information-sharing platform. We can get relevant information through information retrieval tools. In order to get higher search efficiency, the information retrieval technologies based on semantic grid are discussed. Based on analysis of the technologies of grid, semantic grid and information retrieval, the architecture of grid...
Today's Web has provided an infrastructure to build applications that can utilize the Web services standards for developing and deploying services in heterogeneous environments. However the current Web at its current stage lacks the capability of understanding the context in which a particular service has been requested. Therefore we assume that providing semantic annotations through the use of ontologies...
This paper proposes an advanced two-part middleware solution to the problem of integrating resource constrained devices located in the field of factory automation, such as wireless sensor networks, into an enterprise information system. These networks seem to present the most difficult part to be integrated into such information systems. The first part of the proposed middleware is implemented at...
Radio frequency identification (RFID) technology enables information to be remotely stored and retrieved by means of electromagnetic radiation. Compared to other automatic identification technologies, RFID provides an efficient, flexible and inexpensive way of identifying and tracking objects. Asset management is one of the potential applications for RFID technology. Asset management using RFID reduces...
The self-configuration process can simplify the complexity and reduce the cost of the management and deployment of devices, applications and services in smart spaces. Mechanisms inspired from the autonomic computing and pervasive computing can be used to automate management of the heterogeneous space's component. In this paper, we present our work on autonomic pervasive computing and mainly the self-configuration...
Several service discovery protocols are deployed in local-area networks allowing users to be informed about the services in their vicinities. However, these local-area discovery protocols are incapable of exposing the services to remote users. This paper proposes a P2P-based naming system to ensure wide-area service discovery for communications between devices and services often remotely located....
In this paper we present a framework for automation of distributed market place that is based on intelligent software agents and semantic Web services. A multi-agent environment designed for automation of e-commerce activities such as negotiation between buyer and seller, recommendation, and customer decision making. Furthermore we use a semantic Web service middleware called StraBM , advising managers...
In this paper we describe atomic services for distributed digital libraries based on RESTful web services. Our understanding of atomic services (as the basic building blocks for distributed digital libraries) was described in one of our previous works. Those services are: content storage service, metadata storage service, composition and relation service, and search service. Communication protocols...
Recent years have seen a proliferation of work on the Semantic Web, an initiative to enable intelligent agents to reason about and utilize World Wide Web content and services. Concurrently, the networking community has developed a concept of the knowledge plane, using artificial intelligence to reason about and manage network behavior. These two efforts have progressed independently despite potential...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
