A Maritime Spectrum Sensing Scheme Based on Ad Hoc Network and Non-uniform Quantization

Radio communication, one of the key components in maritime communication system. has drawn much more attention because of the increasing number of maritime navigation. In this work, an efficient spectrum sensing strategy based on Ad Hoc network is proposed to improve the robustness and accuracy of maritime radio communication. At first, the network nodes (for example, ships) will be divided into different sub networks according to Ad Hoc network protocol. In the second stage, the mathematical detection probability model of spectrum sensing is constructed. Subsequently, cooperative spectrum sensing combined with non-uniform quantization scheme is given. Simulations have been carried out to illustrate the high detection probability with high robustness of the proposed spectrum sensing scheme. Therefore, it is feasible and advantageous to apply the presented spectrum sensing scheme for improving the accuracy and stability of the maritime radio communication.
