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

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.
