The opportunistic cooperative platform and adaptive cooperative control scheme were proposed based on the\nredundancy degree and priority of cooperative data packet, as well as selective characteristics of time domain and\nfrequency domain. First, opportunistic cooperative platform was defined according to the cooperative data stream\nscale, mapping algorithm, and priority and redundancy of cooperative data packets. Second, under the single or\nmultiple relay network environment and mobility of sensors, the selective characteristics of time and frequency\ndomain were studied. The active domain and negative domain were proposed for adjusting and improving the\nopportunistic cooperative platform. Third, the opportunistic cooperative control mechanism based on selectivity of\ntime domain and frequency domain (OCC-TFD) was proposed for improving the performance of wireless sensor\nnetworks. Finally, the mathematical results demonstrated that the proposed platform and scheme can provide\nreliable, robust, and efficient data communication services of wireless sensor networks.
