Wireless sensor networks, with their capability to capture physical phenomena at micro-scale, have changed how we collect and analyze data from the real world. Especially, using low-power cameras we can design interesting applications that provide us with previously difficult-to-capture information from the real-world. While cameras hold privacy threats in human-residing environments, they can be...
Most of the existing various kinds of clustering algorithms, it is only in the process of clustering by specific routing clustering algorithm select appropriate cluster head to reduce the energy consumption of the whole sensor network, does not take into account numerous due to high density network node in the network, there is a large number of redundant nodes in the cluster. Combined energy consumption...
With the ubiquity of mobile appliances, efficient wireless access has become an urgent need for mobile users. Efficient wireless access requires accurate radio signal maps. Unfortunately, most of solutions could not be applied to large-scale urban space. Crowdsensing schemes could leverage the smartphone to sense WiFi signals, but could not provide accurate map because of the intolerable noises in...
Representational State Transfer (REST) is a web architecture that take the advantage of Hypertext Transfer Protocol (HTTP) to invoke a certain code in the server to do action, either to store, update, delete, or query a value in the server. This kind of implementation are the basis of all Application Program Interface (API) system used by the web application. API provide a tools for creating a software...
The energy-saving research of virtualization of the cloud computing platform shows that there are problems in the management mode of the existing virtualization platform. This model is based on a single node managing the whole platform and the single model is responsible for migrating as well as scheduling all of the virtual machine. The migration scope of virtual machine for these models will be...
Buildings will be more and more automated in future to cater for user's comfort, security and energy efficiency needs. Most of the building automation devices are expected to be in operation for a number of years. However in future, markets will be shared by a number of communication standard, which implies that the user may want to upgrade their device to another communication standard easily without...
In this paper we describe the design and implementation of a GPS-enabled mobile wireless sensor network system for tracking the locations and pasture utilization of livestock herd in Mongolian nomadic herding. The system consists of a mobile sink node, sensor nodes and a livestock management server. To solve the problems of network scalability and mobility, a ZigBee mesh network is adopted as a wireless...
This paper presents the use of the Business Intelligence process and some of its technologies to perform monitoring and meta-monitoring actions on sensed data and physical components that compose an environmental monitoring platform. These actions are mainly related to the capture of data that are the input to carry out the support of the decision-making process in the regulation and control of environmental...
The role of Internet of Things (IoT) in facilitating connectivity of the wireless sensor network (WSN) to the remote server or cloud over the Internet encourages the formation of a highly complex system. This has significant potential for WSN softwarization or open flow through software defined network (SDN). It enables the interaction between the physical and virtual sensor networks resulting in...
Environmental contaminations such as fine particulate matter (PM2.5) and ultraviolet (UV) are expanding public health concerns globally. Existing centralized monitoring stations, however, are unable to properly estimate human exposure due to the low resolution spatiotemporal data. Wireless Sensor Network (WSN) uses real-time capable instrumentation could not only provide fine-grained readings of multiple...
Bicycle-sharing is an exciting new model of public-private transport provision that has quickly emerged in the past five years, and represents a possible way for enhancing sustainable mobility in smart cities of the future. This paper proposes a wireless sensor network based management system for electric bicycle-sharing of new design, where each bicycle and docking station is equipped with a measurement...
Now-a-days, the release of hazardous gases is one of the major threat not only for the environment but also for climate and lives. Both global and local extensive ecological damage is responsible for this case. There are a number of sources for gas emission, like; exhaust gases from industry as well as traffic, fires flue gases, waste disposals, various incidents at the chemicals geo-dynamically active...
To provide higher life quality for people in developing countries through the use of web and embedded systems, healthcare information should be online and accessible from anywhere in the world and the system should be affordable to mass people. This research examines wireless sensor network with real-time remote identification and monitoring of regular and critical healthcare information using low...
This paper addresses an efficient data collection scheme based on the cooperative communications by using the UAV for wireless sensor network (WSN). Specifically, we propose a novel system architecture and MAC protocol, which is included how to select the target cooperative sensor node and which sensing data should be retransmitted by using the decided cooperative sensor node. In our evaluations,...
The fault-tolerant character of WSN protocols and applications that do not assume completely reliable systems legitimize undervolting - a highly efficient energy management technique where the supply voltage is set below the minimum specifications. As has been shown in earlier work, by using thereliable IdealVolting undervolting scheme the lifetime of WSN applications can be increased significantly...
Constrained Application Protocol (CoAP) was developed to support the communication between resource constrained nodes via low-power links. As an Internet protocol, CoAP needs congestion control primarily to stabilize the networking operation. In this paper we propose a new round trip time based adaptive congestion control scheme, which improves CoAP by utilizing the retransmission count information...
The article describes a comprehensive system of mobile sensor units for air pollution measuring in urban areas. The system uses a mobile unit containing small electrochemical sensors or photoionization detector and a Bluetooth Low Energy communication module. The Pollution Gathering application was developed for processing data received from the unit on an Android Smartphone. It uses smartphone's...
Wireless Sensor Networks (WSNs) are popular for their usage in various application like environmental monitoring because of their small size and ease of deployment. However, there is a considerable cost of owning and maintaining involved which might impede small to medium scale industries from availing their services. Even for large-scale industries, WSNs deployed and maintained with so much financial...
