The increasingly extensive availability of location- acquisition technologies (such as GPS and GSM networks) and mobile computing techniques have generated a lot of spatial-temporal trajectory data which represents the mobility of diversification of moving objects such as people, vehicles, and animals. This brings new opportunities to understand the movement behaviors of moving objects in mobile social...
In vehicular ad-hoc network (VANET), the reliability of communication is associated with driving safety. However, research shows that the safety-message transmission in VANET may be congested under some urgent communication cases. More spectrum resource is an effective way to solve transmission congestion. Hence, we introduce cognitive radio (CR) enabled VANET (CR-VANET), where CR device can detect...
At present, RFID is used in some practical fields such as supply chain management, stock management, and so on. However, for the cost reason, the RFID tags are not suitable for individual items, especially for lower-priced goods. In this paper, firstly, the features of logistical unit in the distribution are characterized, and its information is abstracted into a "tree" data structure. Secondly...
There are many applications, such as image-based rendering, where multiple views of a scene are considered simultaneously for improved analysis through employing strong correlation among the set of pixels corresponding to the same physical scene point. While being a useful tool for modeling pixel interactions, Markov random field (MRF) models encounter challenges in such cases since they assume strong...
