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...
A Mobile Social Network (MSN) platform is proposed in this paper, which can be used to research and simulate in MSN. Location and relationship are main features of Mobile Social Network Service (MSNS). They can help with many studies, such as user behaviour analysis and group analysis. In our platform, we collect user location and relationship information from three famous MSNS & SNS (Foursquare,...
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...
Web information scattered among the Web pages, and each store in its own structure and form. It is very difficult to meet the people's information searching needs rely on traditional search engine. A method of WEB content discovery based on Ontology-similarity is proposed in this paper to help people access information more effectively. In this way the author defines an application domain ontology...
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...
For the problem of multimedia applications not obtain assuring service immediately after mobile IP handoff we propose dynamic policy and design the dynamic policy scheme of resource management in mobile IP. Based on the prediction information of the mobile node, the mechanism automatically produces dynamic policies to do admission control and to prepare resources before handoff occurs. And then it...
