Design, development and performance evaluation of a low-cost, Low-power wake-up radio system for WSN
(2013-11-01)
Article
Restricted access - publisher's policyEnergy-efficient operation is a challenge for wireless sensor networks (WSNs). A common method employed for this purpose is duty-cycled operation, which extends battery lifetime yet incurs several types of energy wastes ... -
Energy efficient wireless networking of sensor nodes
(2013)
Conference report
Open AccessWireless sensor networks have paved the way to a new era in user applications, where information can be sensed, processed, and distributed from remote environments with minimal or no human interaction. As the sensor nodes ... -
IEEE 802.11-enabled wake-up radio system: design and performance evaluation
(Institution of Electrical Engineers, 2014-09-25)
Article
Open AccessToday, the vast majority of personal communication devices, such as laptops, smartphones, and logically wireless fidelity (Wi-Fi) access points feature IEEE 802.11 chipsets. In turn, wake-up radio (WuR) systems are used ... -
Infrastructureless smart cities. Use cases and performance
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference report
Restricted access - publisher's policySmart cities are a hot topic nowadays for several reasons. For city managers and citizens a smart city is a concept that should allow providing better services and/or with more efficiency. For technicians a smart city ... -
Networking solutions for connecting bluetooth low energy enabled machines to the internet of things
(2014-11-01)
Article
Restricted access - publisher's policyThe next wave driving the expansion of the Internet will come from the Internet of Things. Bluetooth LE is a rapidly emerging ultra-low-power radio technology expected to be incorporated in billions of IoT devices in the ... -

Time-Knocking: a novel addressing mechanism for wake-up receivers
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference report
Restricted access - publisher's policyWake-up radios present a promising alternative to traditional duty-cycle approaches, by reducing overhearing and by eliminating idle listening completely. However, energy-efficient operation of the wake-up mechanism is ... -
Wake-up radio as an energy-efficient alternative to conventional wireless sensor networks MAC protocols
(Association for Computing Machinery (ACM), 2013)
Conference report
Restricted access - publisher's policyThe use of duty-cycling in Medium Access Control (MAC) protocols effectively helps improving the energy efficiency of wireless networks. However, while the benefits of these protocols are unquestionable, most of them still ...
