How to achieve desired accuracy of RFID localization is challenging for high dynamic and sparse environments, especially for anisotropic RFID tags. We introduce a new method of measuring location of the active RFID tags in three-dimension space to improve localization accuracy. This research (i) provides directional signal-distribution models for both horizontal and vertical orientation of anisotropic...
In order to increase the probability of delivering warning messages to all vehicles (or nodes) in the Zone Of Relevance (ZOR), Vehicular Ad Hoc Networks (VANETs) adopt the periodical broadcast to disseminate warning messages. The broadcast way brings the problem of how to set the suitable message lifetime for the propagation of the warning message. To tackle the aforementioned problem, this work adopts...
Predicting the centrality of nodes is a significant problem for different applications in Opportunistic Mobile Social Networks (OMSNs). However, when calculating such metrics, current studies focused on analyzing static networks that do not change over time or using aggregated contact information over a period of time. Furthermore, the centrality measured in the past is not verified whether it is...
Topology partition imposes significant challenge on reliable delivery of warning messages to vehicles in the zone of relevance (ZOR) in Vehicular Ad Hoc Networks (VANETs). In order to improve the probability of delivering warning messages to all vehicles in the ZOR, VANETs rely on periodic broadcast to disseminate warning messages, which brings the problem of how to set proper message lifetime for...
