摘要 This study analyzes the impact of Physical-layer Network Coding （PNC） on the throughput of a large random wireless network, including one-dimensional and two-dimensional networks. Three different transmission schemes, （1） a traditional flow-based scheme, （2） a network coding scheme, and （3） the PNC scheme are compared to show that the PNC scheme improves wireless network throughput by a constant factor without changing the scaling law compared to the traditional flow-based and network coding schemes. Furthermore, PNC can reduce the effect of interference for the one-dimensional networks, and has a tighter throughput bound for the two-dimensional network.
