【摘要】:提出了一种基于流内与流间网络编码的延迟容忍移动传感器网络(DTMSN)高效广播传输机制.在该机制中,汇聚节点利用随机线性网络编码将原始数据处理成编码包,然后转发给传感器节点.传感器节点间利用一种优化的机会网络编码算法交换编码包.当传感器节点收到足够多的线性无关编码包时解码得到原始广播数据.理论分析和仿真实验表明,与仅基于随机线性网络编码的广播传输机制相比,该机制能进一步减小广播时延和网络负载.
[Abstract]:An efficient broadcast transmission mechanism for delay tolerant mobile sensor networks (DTMSN) based on intra-stream and inter-stream network coding is proposed. In this mechanism, the convergent node processes the raw data into coding packets using random linear network coding and forwards them to the sensor node. Sensor nodes exchange packets using an optimized opportunistic network coding algorithm. The original broadcast data is decoded when the sensor node receives enough linearly independent coding packets. Theoretical analysis and simulation experiments show that the proposed scheme can further reduce the broadcast delay and network load compared with the broadcast transmission mechanism based on stochastic linear network coding only.
