High density deployment of wireless sensor networks in a same monitoring area may result in strong channel interference from different networks. In order to address the interference of co-channel or adjacent channels, we investigate the problem of channel allocation to improve the system performance for multiple wireless sensor networks. In this study, we first derive a channel interference model to evaluate the interference effect in terms of bit error ratio of the system. Then, a channel allocation optimization problem is formulated. We propose a genetic algorithm-based channel assignment method to minimize the interference effect. Simulation study has been performed to validate our algorithm.
