    Recently, grid and peer-to-peer overlays have attracted attention from research communities as well as industry. However, the overwhelming majority of industrial, commercial and academic activities are geared around applications, servers, and middleware. There have been some efforts in the management of the underlying networks (the connectivity for the overlays), but far from enough. This paper pr... View full abstract»

    A dynamic cooperation model for different agents' message exchanging is proposed. It is thought that the curve of surrounding words' relevant influence approximatively fits normal distribution with a mean of 0 and a standard deviation of σ. Following those mechanisms, agent-based selective information retrieval based on topical crawling, high-performance indexing and an efficient search algo... View full abstract»

    Topological dynamics of mobile peer-to-peer are exacerbated by the changes of mobile user's location and interest. We observe that the velocity representation of mobile nodes provides a characterization of the mobility groups. We attempt to predict the future availability of wireless links based on group mobility model. Intuitively, mobile peers within the same group tend to have a high probabilit... View full abstract»

    Measuring the bottleneck bandwidth of a path is useful to many applications. The existing tools to measure the network bottleneck bandwidth are mostly based on the packet pair technique. But the intrinsic error exists in packet pair technique due to the effect of the data link layer, and the incorrect results obtained by the filter algorithm when the network load is heavy. To resolve these problem... View full abstract»

    With the proliferation of Web services specifications, the question of which of the multiplicity of technologies to adopt arises. While sometimes the decision can be based purely on matching requirements to protocol capabilities, a harder consideration is whether the chosen specifications will enable wide interoperability with other systems, or lead to an architectural dead-end. We present a risk ... View full abstract»

    Humans naturally employ a process of iterative refinement when they search for information, clarifying their intentions and adjusting their goals in response to what they encounter. We propose to develop tools specifically to facilitate this process, and hypothesize that they will help users converge on their desired information more quickly. This work presents a layered extension to the Google We... View full abstract»

    The problem of fair exchange is a fundamental problem in secure electronic transactions and digital rights management. Park et al. (2003) presented an optimistic fair-exchange protocol based on RSA. Dodis and Reyain (2003) analyzed the vulnerability of Park's scheme and presented an optimistic fair-exchange protocol based on GDH. This paper point out that Dodis and Reyain's scheme is also insecure... View full abstract»
