This paper proposes a MAC protocol with sensors non-autonomous moving. The protocol can quickly respond to incidents and full account of energy consumption. In order to improve the connectivity of the mobile sensor network, this paper has a research on drift trajectory generation algorithm. To test and verify, this paper uses MATLAB as a simulation tool, collect the speed and direction generate by algorithm and make a comparison between the virtual trajectory and true trajectory. Results shows that the virtual trajectory and true trajectory are matching
