To minimize the outage probability of two-way multi-hop network using Physical-layer Network Coding (PNC), an Optimal Power Allocation (OPA) scheme was presented in the paper. OPA scheme for a three node network and for networks with more nodes were proposed respectively using convex optimization theory and its outage probability were derived. Rayleigh fading was considered in all links. Numerical results show that the proposed OPA scheme achieves a much lower outage probability than the Uniform Power Allocation (UPA) scheme regardless of total transmission power or the nodes number.
