英文摘要：

The wireless sensor communication performance deterministic upper bounds need to be accurately calculated for its real-time attribute.The overall performance is analysis and evaluated for WSN which schedule poly is ensure real-time data flow first.The end-to-end communication performance model is built-up based on deterministic network calculus.The node′s backlog upper bound,the end-to-end upper delay bound and the end-to-end upper delay jitter bound had been derived for wireless sensor network using network calculus theory.Simulated results for different data flows were bounded by theoretical results,These show the deterministic performance upper bounds model perform well.This work make the performance research of WSN become more completeness.
