物理层网络编码在数据会聚无线自组织网络中的容量增益研究

为研究物理层网络编码.(Physical-layer Network Coding，PNC).方案在数据汇聚无线自组织网络中相对于传统方案能够获得的容量增益，该文通过稀疏割容量分析推导得到PNC方案平均每节点信息传输速率的上界和下界。与传统路由方案及传统网络编码方案相比，在数据汇聚无线自组织网络中应用PNC方案能够提升网络容量的数量级。

Study on the Capacity Benefit of Physical-layer Network Coding for Wireless Data-gathering Ad hoc Networks

This paper studies the network throughput capacity gain of Physical-layer Network Coding (PNC) in data-gathering wireless ad hoc networks. The throughput upper bound and lower bound with the PNC scheme are derived by utilizing the sparsity-cut capacity analysis. The result of this paper implies that by using PNC, an order capacity gain can be obtained over traditional routing and network coding schemes in wireless data-gathering Ad hoc networks.
