Abstract: A crowd sensing network takes the use of the dense distribution, frequent encountering, and social property of mobile terminals in real society. In a crowd sensing network, the datasensing transmission is based on the collaborative opportunistic transmission, the final message data will be forwarded to the user who is willing to report data (e.g. high battery capacity and with low-cost Internet link equipment), and then report the perceptual data to the backdrop data center. In the mobile crowdsensing network, there is a big difference in the social ability of each node carrier, so that the data forwarding capability of each node is also different. In this paper, we first analyze the shortcomings of node based on node quantization. On these grounds, this paper proposes a data forwarding mechanism based on node function and node centricity, and gets its performance improved effectively, and reduces the energy consumption of nodes.
