Actuator network envisions the control provision of resources on Internet. Actuator network middleware supports the message transmissions for controlling the behavior of the environment or physical systems. This paper presents the actuator network middleware based on ID for control environment using multiple actuator devices. The middleware presented here is part of an IoT system. The proposed middleware...
Mobile devices and applications designed to assist people during emergencies are becoming more common, but their utility depends heavily on the availability of network and appropriate services. This article presents the rescue worker interface (RWI), a cloud-based service to support fire wardens in the event of a building fire emergency and to assist them in carrying out evacuation tasks in a timely,...
According to the specific business requirements of the meteorological wireless sensor network (MWSN), we analyze and summarize the principles and problems of the existing Web real-time communication technology, and put forward the realtime meteorological information publishing platform (RT-MIPP) solution based on WebSocket. We first analyze and classify the observational data of MWSN, and design the...
Sensor/actuator networks are becoming hierarchical, with wireless ad hoc networks interconnected via infrastructured wireless (e.g. the cellular network) and the Internet. This trend is being driven by new application domains such as cyber-ecological systems. In these systems, sensor/actuator networks and data centers form a geographically-distributed closed-loop system capable of near real-time sensing...
The "Internet of Things" along with the "Internet ofServices" is expected to undertake a significant role in our lives for the years to come. The versatility of its components and the ability to harvest, as well as consume, ubiquitous services in addition to information from different providers, are among the main challenges for the expansion. Main information producers will consist...
Sensor and Actuator Networks (SAN) are distributed systems deployed to sense, monitor and act on the environment. They may include any of the following: sensors, wiring, embedded system components, wireless communication and backbone servers. Given current technological advances, costs and flexibility advantages of wireless sensor networks technology, wireless SAN (WSAN) deployments are being considered...
The Internet of Things vision states that sensors and actuators shall be integrated into the global Internet to facilitate an interaction with and integration of the physical environment. The development of enabling technologies like uIPv6 and 6LoWPAN provide the basic requirements for this interconnection. However, a seamless Internet-connection and interconnection between sensors and actuators can...
This paper describes a self-configurable middleware and a node execution platform to support autonomous sensor networks. We achieve self-configuration by scheduling and strategies similar to load balancing (mapping) that is integrated in our proposed middleware. On the node execution platform we decide on the fly between microprocessor and FPGA realization of hybrid tasks. We propose a combination...
In this paper, we introduce a ubiquitous voice message broadcast system - called u-Paging, by combining the technique of location-awareness and the voice message delivery service in ubiquitous sensor network environment. To actualize the u-Paging service, specialized hardware and middleware architecture are proposed under the wire/wireless hybrid ubiquitous network.
This paper presents a project that has been recently funded by means of the ERC Starting Grant (http://erc.europa.eu/). The main goal of the project is to develop a new generarion of wireless sensor networks infrastructure to support innovative services for ubiquitous sensing and video. The work is in a very preliminary phase so the paper presents a general overview and the main challenges.
Developing a large sensor-based observation system faces two serious challenges: 1) incompatible sensor technologies from different manufacturers; and 2) complexity of the data streaming process. Sensor Abstraction Layer (SAL) is a middle-ware integration platform which enables a single interface to view and control heterogeneous sensors regardless of the technologies involved. Although SAL addresses...
In this paper, a novel interoperable wireless sensor network (WSN) model using multi-agent-based middleware are proposed. This model provided generalized frameworks to address some critical issues existed in the WSN such as interoperability, time synchronization, power management and distributed computation. To address these issues, we developed a model that was based IEEE 1451 and IEEE 1588 standards...
In this paper we describe SpartanRPC, a secure middleware technology for wireless sensor network (WSN) applications supporting cooperation between distinct protection domains. The SpartanRPC system extends the nesC programming language to provide a link-layer remote procedure call (RPC) mechanism, along with an extension of nesC configuration wirings that allow specification of remote, dynamic endpoints...
In the supply chain management,the warehouse management is an important component.It is necessary to improve storage management efficiency and reduce operational costs and error rates.Therefore,it needs a new logistics information technology to replace the traditional mode of storage operation. RFID (radio frequency identification) and WSN (Wireless Sensor Network) technology can precisely solve this...
In this paper we propose a system architecture for telemonitoring system. The proposed architecture is not limited to only indoor environment. By employing a mobile phone that implements a personal server, the system also supports the monitoring of old people while away from home. In addition to the system architecture, we also propose the middleware architecture for the personal server and the cross-layer...

Minimally invasive surgery (MIS), where the surgeon operates trough small incisions, can greatly benefit from wireless sensor technology. Wireless body area networks are a promising field that is able to increase sensing ability in the patient while being almost unobtrusive, which is an important requirement in this type of surgery. In many cases, wired sensors must also be used in order to support...
