摘要:
 网络编码被应用于多播、广播和单播中。而把网络编码应用于无线传感网汇播的研究还处于理论和仿真阶段。把网络编码应用于实际环境中，需要考虑节点同步、开销控制、线性独立的编码系数等问题。为了研究网络编码对传统汇播的影响，文中在真实无线传感网中实现了一种基于网络编码的汇播机制。文中基于TDMA实现同步和开销控制，采用线性网络编码来进行编码，采用高斯消除来进行解码。文中以收集率为参考，实验结果表明，网络编码能给传统汇播带来可靠性增益。
Abstract:
 Network coding is applied in multicast,broadcast and unicast. But the study of applying network coding in convergecast in wireless sensor networks is still at the theory and simulation stage. Applying network coding in real environment, the questions like nodes’ synchronization,overhead control and linear independent coding coefficient should be considered. For studying the influence of network coding to traditional convergecast,network coding-based convergecast scheme in real wireless sensor network is realized in this paper. The nodes’ synchronization and overhead control is realized based on TDMA,and linear network coding is used to do encoding, and Gaussian elimination is applied to do decoding. Collection rate is adopted as reference,and the results show that network coding can bring reliable gains to traditional convergecast.
