The heterogeneous SIS model for virus spread in any finite size graph characterizes the influence of factors of SIS model and could be analyzed by the extended N-Intertwined model introduced in [1]. We specifically focus on the heterogeneous virus spread in the star network in this paper. The epidemic threshold and the average meta-stable state fraction of infected nodes are derived for virus spread...
It is often long time-consuming for applying the traditional genetic algorithm to the PID optimization of hydro-turbine governor. To address such issue, a multi-agent based distributed genetic algorithm (MAGA) is proposed. Based on establishment of the non-linear digital simulation model of generating units, a distributed mobile computing platform implementing MAGA is built using agent middle ware,...
The k-ary n-cube which has an n-dimensional grid structure with k nodes in each dimension has been a popular topology for interconnection networks. Analytical models for k-ary n-cubes have been widely reported under the assumptions that the message destinations are uniformly distributed over all network nodes and the message arrivals follow a non-bursty Poisson process. Recent studies have convincingly...
The peer-to-peer (P2P) live video streaming system has been demonstrated to have great potential in the public Internet; the large-scale deployment of such systems, however, critically relies on how effective they can deal with the high dynamics encountered, in particular during flash crowd. The rationale behind is that the scaling in P2P live video streaming systems is heavily determined by the timing...
Pipelined circuit switching which combines the advantages of both circuit switching and wormhole switching is an efficient method for reconciling the conflicting demands of communication performance and fault-tolerance in interconnection networks of multi-computers. The arrival process and destination distribution of messages generated by real-world parallel applications can markedly affect the performance...
IDOP_SP (IPTV DRM interactive operating platform security protocol) protocol is a applied complicated protocol which distributes digital media content in the Internet. The flow of the protocol is based on the behavior of Web service composition and the digital content is transmitted to the customer in the form of hybrid digital objects. But the protocol security only can be assured after the protocol...
