Provided by Google, Eddystone standard consists of a beacon technology, open-source format, unidirectional and proximity-based Bluetooth® Low Energy (BLE) standard. Eddystone can support multiple different payloads, portable for IOS and Android with a ranging of approximately 50 meters. This paper analyses different metrics of a Verilog digital logical implementation of a Google Eddystone...
At three key sporting venues of the RIO 2016 Olympic Games, an innovative remote powering solution was used to deliver power from a central source to Remote Radio Units (RRUs) located on cell towers. The solution effectively powered the RRUs from a centralized source of DC power while providing battery backup protection. This paper describes the powering challenges faced by the Wireless Service Provider...
The Internet of Things (IoT) is widely predicted to comprise billions of connected devices, many of which will be wireless sensor nodes (WSN). Energy efficiency is a huge challenge here, followed by node cost and ease of software (SW) development. Addressing all of the above, this paper presents an 11.7 pJ/cycle subthreshold ARM Cortex-M0+ WSN processing subsystem implemented in low-leakage 65 nm...
Hybrid systems at the local scale (from nanogrids to low voltage microgrids) that include renewables have experienced an extraordinary growth all over the world and have attracted the attention of both academies and industries to build economic and environmental appealing solutions based on innovative control architectures. These architectures have to take into account the uncertainty and the intermittency...
Today, there is a long-term trend towards bi-directional and flexible charger functions for not only drawing current from the grid but also feeding excess energy back into it. The Configurable Modular Multilevel Converter (CMMC) offers a large flexibility in order to handle the different voltage levels and current intensities in electric vehicle's battery charging and discharging. Therefore, this...
In this paper we suggest a multiagent based middleware architecture that is particularly suitable for supporting wireless sensor network deployments in industrial environments like mines and chemical processing plants. Our intention is to make the proposed middleware architecture to be as closely aligned to the Foundation for Intelligent Physical Agents standards as possible. The existing agent based...
The increased availability of mobile broadband connec- tions enables the expansion of software downloads to mobile devices. This leads to greater number of available services and a better utilisation of the computational power of mobile devices. The downside of this increased software availability is an increase in the possible attack vectors. One scenario is the misuse of resources, for example,...
