Stereo vision is an active research topic in computer vision. Point Grey® Bumblebee® and digital single-lens reflex camera (DSLR) are normally found in the stereo vision research, they are robust but expensive. Open source electronic prototyping platforms such as Arduino and Raspberry Pi are interesting products, which allows students or researchers to custom made inexpensive experimental equipment...
Proximity-based mobile social networks (PMSNs) are a novel type of social networks, where mobile users can choose potential friends in vicinity by comparing the similarity degree between their private attributes and make new connections through the WiFi/Bluetooth interfaces on their mobile devices. Since users' personal attributes usually contain some sensitive information, users may have increasing...
Proximity-based mobile social networks (PMSNs) are becoming increasingly popular in recent years with the explosive growth of mobile devices, where a user can find a best matching friend in vicinity through profile matching. However, the matching process calls for the publication of users' personal information, which conflicts with users' growing privacy concerns about revealing their profiles to...
Making new social interactions with other users in vicinity is a crucial service in Proximity-based Mobile Social Networks (PMSNs), where a user can find a best matching friend directly through the Bluetooth/WiFi interfaces built in her mobile device. In existing work for such services, users have to publish their interests to do the matching. However, it conflicts with users' growing privacy concerns...
This paper chose the WM-G-MR-09 chip, designed and implemented WiFi communication module, set up a real mobile network environment base on Windows CE operating system platforms and IEEE 802.11b wireless network interface. Achieved AODV (Ad-Hoc on-demand Distance Vector) routing algorithm module by calling the API in an adding routing function module. The validation and testing for the algorithm module...
Low energy neighbor discovery, group formation, and group maintenance is a fundamental service in mobile sensor networks. Traditional solutions consider these protocols separately. In this paper, we introduce WiFlock, an energy-efficient protocol that combines discovery and maintenance using a collaborative beaconing mechanism. WiFlock combines a coordinated synchronized listening and evenly-spaced...
Broadcast plays an important role in route discovery, source paging and information diffusion for mobile ad hoc networks. Flooding is a simple solution to broadcast, but it may cause high redundancy, contentions and collisions, a phenomenon referred to as broadcast storm. Counter-based and position-based solutions can avoid blind flooding to some extent. However, the uniformity aroused by constant...
Passenger line flow in China is so huge that current ticketing systems cannot be viewed optimistic. After pointing out the disadvantages of existing telephone and web network ticketing systems and further comparing barcode, two-dimensional barcode and RFID(Radio Frequency Identification), this paper proposed a new ticketing system based on C/S architecture and two-dimensional(2-D) barcode on mobile...
A kind of management model in the mobile transmission resource management system (short for TRMS) is presented . With this model, the efficiency, expansibility of managing the transmission resource can be improved and the complexity can be reduced.
A project of mobile value-added service based on P2P is proposed. In this project, wireless devices can build a P2P network dynamically and they can access and transmit information point to point. The idea will adapt to the 3G wireless network and it will become a effective solution for mobile value-added services on 3G. Utilizing JXTA and J2ME, a platform based the project is realized. The module...
A dynamic policy based network management scheme is presented for the problem that traditional policies can??t preferably adapt to change of network state. It defined dynamic policy form and appended new module PMA to IETF policy frame to improves the adaptability of policie. Then the application of dynamic policy to allocate resource is presented. By experiment and analysis, it is shown that this...
