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,...
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...
Nowadays, Wireless Sensor Networks (WSN) are already a very important data source to obtain data about the environment. Thus, they are key to the creation of Cyber-Physical Systems (CPS). Given the popularity of P2P middle wares as a means to efficiently process information and distribute services, being able to integrate them to WSN's is an interesting proposal. JXTA is a widely used P2P middleware...
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...
Today's abundance of sensors and their wireless/wired networks, coupled with a growing plethora of applications, necessitate a dynamic approach to the assignment of tasks to a network. The current practice in WSN design is almost always application specific, due to functional and resource tradeoffs that have justified much of the tailored research done so far. Identifying this as a major bottleneck...
Wireless sensor networks (WSNs) are deployed to sense, monitor and act on the environment. Deployments in scenarios such as industrial sense and react environments require a set of functionality, and for both ease and reconfiguration capabilities it is important to offer an appropriate framework. We propose a framework for interaction with real-world devices by abstracting proprietary protocols, allowing...
The hardware capability and software functionality of sensor networks have continuously evolved. Apart from the merits brought by technological advances, this rapid upgrading pace poses great challenges to make heterogeneous sensor node platforms interoperate with each other. In this work, a service-oriented Application Programming Interface (API) is proposed for wireless sensor networks to handle...
In this paper, we explore the implementation of a smart monitoring system over a wireless sensor network, with particular emphasis on the creation of a solid routing infrastructure through the Routing Protocol for Low- power and lossy networks (RPL), whose definition is currently being discussed within the IETF ROLL working group. Our framework is based on a very lightweight implementation of the...
The problem of integrating the ad hoc networks and especially the Wireless Sensor Networks (WSN) with the Internet has attracted significant research and implementation efforts so far. Admittedly, not all of them have been widely adopted and established as prevalent standards or solutions in this technical area. In this paper we survey the proposed interconnection models and the relevant architectures...
Wireless Sensor Networks (WSNs), are a challenging and evolving area where applications can demand services, distribution, modularity and intelligence. WSNs are a versatile field with varying software architectures, which has led to the development of a plethora of WSN middlewares, management and reconfiguration protocols. To realize the potential of evolving WSN technologies and software architectures...

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...
Considerable research has been done on different aspects of sensor networks. However management issues for these devices are still little explored. Nonetheless, with the increasing number of heterogeneous distributed sensors in various application domains, their management gains more and more importance, in particular for domains where requirements in terms of quality service, reliability, security...
Within a smart home environment the information processing is supposed to be thoroughly integrated into everyday objects. This introduces the need to keep track of the everyday objects and their state changes produced based on the userpsilas interaction with them. Such information is useful in recognizing the userpsilas activities, situations, etc. In this paper we present a ZigBee communication protocol...
Many fields of the industrial automation can be already served by wireless technologies. Due to the different requirements regarding the reliability, latency, number of nodes, node density and range to communication systems there is no uniform standard for wireless communication covering all domains of automation. It is to be expected in the future on a strongly increasing number of radio technologies...
Smart Homes uses different devices including sensors and actuators to provide services that assist in performing the activities of daily living. Currently these smart homes are developed in a manual and adhoc way. Manually configured smart homes create scalability, extensibility and cost problem. The need for a uniform platform for intercommunication among devices and a middleware abstraction using...
Energy consumption in wireless sensor networks is one of the most important challenges for designing appropriate middleware protocols for specific applications.
