Social network has extended its popularity from the Internet to mobile domain. Pervasive social networking (PSN) supports instant social activities based on self-organized mobile ad hoc networks. PSN is useful in reality when fixed networks are unavailable or inconvenient to access or when people are in vicinity. For supporting crucial PSN activities and enhancing user privacy, securing pervasive...
In heterogeneous network environment, it is important to choose an appropriate access network for a Multimode Mobile Terminal (MMT). Currently, there are some methods proposed to make network access selection decision. However, those methods didn't consider some dynamic attributes and could not offer effective handoff strategies. In this paper, we introduce an Intelligence Access Selection Scheme...
As head-disk clearance has been reduced to nearly 1 nm, and a partial lube-contact head-disk interface (HDI) may even be necessary to meet future magnetic spacing needs, precise characterization of the slider-lube/disk contact state (or depth) becomes increasingly important. The currently used thermal fly-height control (TFC) sliders require a slight touchdown (or contact) to determine the reference...
With increasing diversity and heterogeneity of content access devices and network technologies as well as user preferences, content delivery has evolved into a matter of ubiquitous service where production, delivery and access of content form major challenges for content provider, network operator and user respectively. Content adaptation has been widely acknowledged as one of the most important aspects...
At present, in most RFID systems, data acquisition and system configuration of mobile readers are based on site collection and then synchronization of data and configuration information with server by manual work. Because of extensive application of RFID systems, it may become the critical system of consumer payment, identification and many other service applications. However, data synchronization...
With rapid development of Internet of Things, requirements for sensing layer of the Internet of Things have gradually been deep. RFID, which is one of the perception layer technology, has a long way to run. In this paper, a deep research on management of mobile RFID reader is done. The problem, which is de synchronization of data and configuration information with server, is found. WAN network management...
Accurate localization and navigation are indispensable for mobile agents to walk in large-scale indoor public space, such as intelligent building and disaster rescue. In this paper, an intelligent localization and navigation system called ISILON is designed and developed. The system consists of a mobile terminal and multiple sensor nodes (also called landmarks) installed in the environment. The mechanism...
The combined-GEO-IGSO constellation is the combination of GEO (geostationary earth orbit) satellite and IGSO (inclining geostationary synchronized orbit) satellite. The combined-GEO-IGSO constellation can integrate the advantages of GEO and IGSO to achieve regional coverage. The simulation results show that: the combined constellation can reach higher multi-sat coverage and higher communication elevation...
Mobile networks, in particular the emergence of 3G networks, value-added network services will be brought some new opportunities. Electronic card as value-added services will be more room for development. We design and implement an electronic card system with a combination of the mobile network and the Internet. Users can access it through three ways (web, wap, and sms) to conduct electronic card...
Nowadays, competition of Web-based communities has become very fierce, network communities are seeking for new growth point. Undoubtedly, mobile social network service (MSNS) is one of the most important directions. Few paper about MSNS is focus on the development trend or the technical implementation of MSNS, but not on the design and management of MSNS, which is important for the MSNS. This paper...
