| 摘 要： | 大规模部署的无线传感器网络中，节点状态变化极易导致数据投递率降低。为了建立无线传感器网络应用仿真平台，研究提高数据投递率的方法。通过分析TinyOS操作系统中数据汇聚协议CTP的实现机制以及基于NS2实现CTP协议的原理和方法，采用一种新思路，将TinyOS基于组件化编程思想实现的CTP协议移植到基于面向对象的NS2中，实现了CTP的链路质量评估、信标帧传输控制和数据包转发重传等重要机制，最后进行了NS2仿真实验。仿真结果表明，CTP协议具有高可靠性。

| Abstract: | In the light of low data deliver ratio caused by inconsistent nodes in large-scale multi-hop wireless sensor network,the mechanism of CTP aggregation protocol in TinyOS,as well as the realization of CTP based on NS 2 are analyzed.A new scheme is proposed that CTP protocol is transplanted from component-based TinyOS into object-oriented NS 2,which fulfills link quality estimation,beacon frame transmission control and data packet forwarding,etc.Simulation results show that CTP protocol has high reliability. |
