Engaging end-users in creating data-intensive mobile applications: A creative 'e-learning-by-doing' approach
(2015)Engaging end-users in creative and experiential e-learning activities by giving them the 'right tools' can be viewed as a way to empower end-users in developing their own artifacts. The aim of this paper is to propose ... -
An experimental framework for data gathering and analysis in wireless sensor networks
(2011)In the last decade testbeds have been set-up to evaluate network protocols and algorithms under realistic settings. Moreover, wireless sensors have lately been integrated into testbeds in order to simulate application ... -
Exploiting co-location history for efficient service selection in ubiquitous computing systems
(2005)As the ubiquitous computing vision materializes, the number and diversity of digital elements in our environment increases. Computing capability comes in various forms and is embedded in different physical objects, ranging ... -
Fast power-up active link protection in autonomous distributed transmitter power control
(2008)In this work, we propose an enhancement to the DPC/ALP (Distributed Power Control with Active Link Protection) algorithm that allows fast power ramp-up without compromising the ALP guarantee. The original DPC algorithm was ... -
Interpolating the air for optimizing wireless data broadcast
(2007)Energy conservation and access efficiency are two fundamental though competing goals in broadcast wireless networks. To tackle the energy penalty from sequential searching, the interleaving of index with data items has ... -
A k-anonymity model for spatio-temporal data
(2007)The unprecedented growth In Location-Based Services (LBS) take-up along with the continuously increasing storage capabilities of modern systems, and have facilitated the collection of information related to users activities ... -
Multi-screen lock: Visual passwords from user’s social data
(2019)A critical issue for a mobile device user is the protection of stored sensitive data and their access, via the device. A widely used technique for protecting the mobile device with a display is the lock screen. Many security ... -
A new slicing scheme for efficient use of wireless testbeds
(2009)The gradually growing need for testbed use so as networking algorithms to be validated in real environments, has given rise to optimal utilization of testbed resources. Despite the fact that, many laboratories around the ... -
Novel metrics and experimentation insights for dynamic frequency selection in wireless LANs
(2011)The rapidly increasing popularity of IEEE 802.11 WLANs has created unprecedented levels of congestion in the unlicensed frequency bands, especially in densely populated urban areas. Performance experienced by end-users in ... -
OmniStore: Automating data management in a personal system comprising several portable devices
(2007)The ever growing amount of data generated and consumed on the move using portable devices gives rise to serious data management issues. The fact that each person may own and is likely to carry several such devices further ... -
On service time estimation in 802.11 wlans with heterogeneous traffic sources
(2008)This work presents a simple method to estimate IEEE 802.11 Distributed Coordination Function (DCF) service time. This is the total amount of time needed to transmit a given frame, which is defined as the duration from the ... -
