 Power line communication of the power distribution network requires higher reliability and better standards. In this paper, the ideas of cooperative communication motivate that we have presented a dual heterogeneous networks model with power line communication network and wireless sensor networks. Concatenated channel encoding with cyclic redundancy check code, convolution code, Reed Solomon code and the interleaver are respectively researched, which are used to analyse the performance of dual networks’ communication scheme. The simulated results reveal that the dual networks have better communication quality than the one of single network. Compared to dual-network with RS code, the probability of frame error transmission and bit error rate for dual-network with convolution code are lower. On the basis of the characteristics of two different kinds of concatenated codes, we put forward an improved model, which is more close to reality. The results verify the feasibility of the design.
