End-to-end network throughput enhancement through physical-layer network coding

Physical-Layer Network Coding (PNC) is a promising technique that has great
potentials for improving the achievable data rates of end-to-end flows through higher
packet transmission rates, thereby increasing the overall network throughput. In this
thesis, we study the performance of the PNC transmission techniques for unidirectional
end-to-end flows in multi-hop wireless networks, and compare it with that of the
traditional transmission techniques. We first derive the bit-error rate (BER) that the
PNC transmission technique achieves. Then, using the derived BER, we evaluate and
quantify the achievable network throughput under both the PNC transmission
technique and the traditional technique, where the network throughput is measured as
the aggregate/sum of all end-to-end flows' achievable data rates in the wireless
network. Using extensive simulations, we show that PNC increases the overall
achievable end-to-end flow throughput in multi-hop wireless networks, especially
under medium to high signal-to-noise ratios. / Graduation date: 2012
