In the remote, hazardous, distributed and external environment, such as radiation source, pollutant source and pipeline of petrol, water and gas, it is difficult to collect and send the necessary message in real-time by traditional monitoring ways. This paper briefly describes the design of remote wireless monitoring system based on MCU (Micro-programmed Control Unit) and GPRS (General Packet Radio...
How to improve the scalability and QoS of peer-to-peer on-demand streaming system based on unstructured overlay is still a problem. Researchers have proposed some memory based buffering schemes to archive the targets. Considering the limited space of memory on one peer, a new caching strategy, which can integrate memory-caching strategy with disk-caching strategy, is proposed to make full use of peers...
Software architecture is the bridge from requirement to realization, to determine software quality. Based on analyze the description of software architecture ,this paper derives a performance evaluation models, based on UML collaboration and sequence diagram. Extend Queueing Network Models on route and arrived rate. Finally, use the example of client/server architecture, to prove the approach correctly.
