This paper presents a development environment of Internet of Things, EFAIoT. EFAIoT means an Easy and Flexible Application Development system, which is focus on the Internet of Things field. Our system provides graphic user interface, through which users can build up their own internet of things applications on the semantic layout. A browser based and user friendly user interface was provided to reduce...
As the penetration of Internet into the lifestyle, virtual community has become an important communication approach, and attracted the attentions of e-commerce sites. But so far, the relationships among virtual community involvement, online stickiness and repurchase intention have not yet been studied deeply. In this paper, structural equation modeling analysis method was used to reveal the relationships...
Because online consumers can easily switch to other e-commerce sites, their online loyalty is generally not high. How to attract the attention of online consumers and make them stick with the website has become a big challenge for e-commerce companies. In this paper, the antecedents of online stickiness and its effect on repurchase intention was examined from the view of website design. Structural...
For requirement of MANET accessing Internet, a load-balancing and energy-aware routing protocol is proposed after analysis on MANET routing. This protocol is used for Internet gateway broadcasting route, and it evaluates route with node's residual energy and transmission load. With this protocol node accessing Internet can find a shortest route and avoid low-power node and busy node.
This paper proposes a reusable software dynamic analysis methodology for componentized Internet applications, which is composed of two important parts: execution model construction and runtime behavior analysis. Firstly, the related concepts of behavior observation are presented. Secondly, according to the behavior observations extracted from running applications, the multi benchmarking behavior model...
As multicasting is increasingly used as an efficient communication mechanism for group-oriented applications in the Internet, the research of the multicast key management is becoming a hot issue. Firstly, we analyze the n-party GDH.2 multicast key management protocol and point out that it has the following flaws: lack of certification, vulnerability to man-in-the-middle attacks, and a single-point...
Key management is very crucial in a secure multicast system. The key storage of the group controller and group members, the communication cost and computation cost caused by joining/leaving members, are the determining factors for the performance of the key management system. A scheme is high-performed, if it has the optimal rekeying cost and the lower storage requirements. In order to get the high...
Transmitting high-quality neurophysiology video via the Internet is a challenging problem in telemedicine. We propose a novel video data processing and compression method based on the discrete wavelet transform (DWT). The DWT is utilized to decompose video frames into subframes, different bandwidth budgets are assigned to important and less important regions in each subframe, and several video encoders...
