Communication Performance Deterministic Upper Bounds for Wireless Sensor Networks

无线传感器网络一般具有实时性,其端到端通信性能上界研究具有重要意义.基于确定性网络演算理论,对无线传感器网络为保证实时数据优先的数据转发调度策略进行了性能分析与评价.建立了基于确定性网络演算的端到端通信性能分析模型,经过理论分析得到了无线传感器网络节点的数据队列上界、端到端数据流的延迟上界以及端到端数据流的延迟抖动上界.仿真结果表明基于网络演算理论的无线传感器网络性能上界均在理论计算的上界范围之内.本文的研究使得对无线传感器网络通信性能的研究更符合完备性的要求.

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.
