Recently, narrowband Internet of Things (NB-IoT), one of the most promising low power wide area (LPWA) technologies, has attracted much attention from both academia and industry. It has great potential to meet the huge demand for machine-type communications in the era of IoT. To facilitate research on and application of NB-IoT, in this paper, we design a system that includes NB devices, an IoT cloud...
Wireless charging technologies have attracted much attention from both academia and industry due to their great potential of freeing devices from wires and batteries, becoming one of the key research areas in recent years. Many platforms have been designed based on different charging technologies for a wide range of scenarios, including structural monitoring, habitat monitoring, wearable devices,...
by virtual machines and the reduce of resource utilization caused by migration of a single virtual machine in cloud computing , this paper proposes a load balancing strategy based on data correlation in cloud computing. This strategy finds out the migration unit based on the correlation between the data and the virtual machines used to deal with the same data, and construct the load-intensive data...
In large parking lots, it is generally difficult for drivers to know ahead of time whether there will be available parking spots and where they are. Besides, it is logistically cumbersome to wait in line for paying parking fees when leaving. In this demo, we develop an intelligent parking system called iParking. iParking could help users monitor parking states, search for a vacant parking spot, reserve...
To fully evaluate and compare the performances of channel assignment algorithms, we design a MICAz-based testbed system with GUI interface, which is suitable for most kinds of algorithms. In the proposed system, we can download different algorithms, observe the performance through the GUI interface, and compare the results with simulations. In the demonstration, regret matching based channel assignment...
In this paper, we design and implement a reliable data processing and analysis test bed (NESCTB) for wireless sensor networks (WSNs). It contains 36 wireless sensor nodes connected through Ethernet to a central server so that, with web interface, remote users are able to schedule tasks and monitor the nodes' operations online. In addition, reprogramming and data logging can also be provided via the...
