    Self-Calibration of TOA/Distance Relationship for Wireless Localization in Harsh Environments

    The success of location-based services in open areas, mainly driven by Global Navigation Satellite Systems (GNSS), has pushed the research community towards the development of robust systems that provide a similar localization accuracy in harsh environments, where there is no Line-Of-Sight (LOS) to satellites. Techniques based on Time-Of-Arrival (TOA) measurements...

    An Adaptive Multimedia-Oriented Handoff Scheme for IEEE 802.11 WLANS

    Previous studies have shown that the actual handoff schemes employed in the IEEE 802.11 Wireless LANs (WLANs) do not meet the strict delay constraints placed by many multimedia applications like Voice over IP. Both the active and the passive supported scan modes in the standard handoff procedure have important delay...
