The generation and share of user generated content via online social networks (OSNs) aggressively promotes the substantial growth of Internet traffic. When confronting such massive network traffic, how to improve quality of experience for users remains an important yet challenging problem. Though there exist works on intelligent distribution and caching of user generated content, none of them comprehensively...
By constructing the exponential delay cost function, we formulate the consumer decision model based on the threshold strategies in dual-mechanism, and prove that there exists a unique symmetric Nash equilibrium in which the high-valuation consumers use a threshold policy to choose between the two selling channels. Then we extend our model under general delay cost function, and find that consumers...
Delay Tolerant Mobile Networks (DTMNs) focus on scenarios where most of the time contemporaneous end-to-end paths between source and destination do not exist, and mobility should be explored for message delivery. Ant colony optimization is based on reinforcement learning and is adaptive. In this paper, we propose ACRP: an Ant-Colony-based Routing Protocol for DTMNs. In the protocol, the forward ants...
Electronic commerce is fast expanding all over the world. Currently most B2C (business to customer) electronic commerce focuses on retailing and other online services, such as online banking. Compared with large-scale enterprises and organizations, small businesses find it difficult to involve in electronic commerce because the cost is too high to be affordable. The cost for electronic commerce not...
This discussion concerns 'metrics'. More specifically, we discuss quantitative metrics for evaluating Internet applications: what should we quantify, monitor and analyse in order to characterise, evaluate and develop Internet applications based on reusing existing Internet applications,which is widely available in the Internet. Due to the distinctive evolution nature of Internet applications, assessing...
The recent growth of the World Wide Web has sparked new research into using the Internet for novel types of group communication, like multiparty videoconferencing and real-time streaming. Multicast has the potential to be very useful, but it suffers from many problems like security. To achieve secure multicast communications, key management is one of the most critical problems. So far, a lot of multicast...
The success of Internet allows us to access remote data by using the TCP/IP protocol suite. However, bandwidth and delay have a crucial impact on the quality of a video stream delivered over IP connection. So causal ordered grid architecture is proposed to provide a novel transport protocol to the time-sensitive and ordering-critical video applications. But it indicates that the value of Delta is...
