Nowadays, 3D reconstruction has been introduced in monitoring the package placement in logistic industry-related applications. Existing 3D econstruction methods are mainly based on computer vision or sensor-based approaches, which are limited by the line-of-sight or battery life constraint. In this paper, we propose RF-3DScan to perform 3D reconstruction on tagged packages via passive RFID, by attaching...
Based on studying the characteristics of topology and business model of wireless mesh networks, depth analysis of the suitable routing protocol type for WMN was given out which shows that proactive hop-by-hop routing is most suitable for WMN. On the basis of Optimized Link State Routing which is a typical proactive hop-by-hop routing protocol. A routing protocol P-OLSR of perceptive 1inks is proposed...
This thesis attempts to study the consumer satisfaction of communications enterprises from the perspective of experiential marketing. In order to make the study more targeting and convincing, this thesis selects China Mobile as its studying object, adopts theories from management, marketing, consumer behavior and other courses theories, and employs the research method of integrating theoretical and...
Considering the constraints brought by mobility and resources, it is important for routing protocols to efficiently deliver data in intermittently connected mobile networks. Different from previous works that use the knowledge of previous encounters to predict future contacts, we propose a storage-friendly region-based protocol, i.e., RENA, in this paper. Instead of using temporal information, RENA...
Power saving (PS) focused on IEEE 802.16 wireless metropolitan area network (WMAN) has been intensively investigated from both theoretical point and perspective of design and implement. Though the IEEE standard of 802.16e leaves room for flexibly designing, we found that dozens of studies set their focus on mechanism improvement, yet seldom considered when those optimized PS mechanisms might, or should...
The wireless networks are running following a serious of mechanisms, which is the composition of various networks mechanisms. However, the existing security framework is built for a single or independent network, far from the real heterogeneous networks. In this paper, based on the traditional framework in wireless networks, a trusted and secure framework is proposed to manage the credibility of the...
