Abstract: For adapting to a novel architecture of WSNs, which supports information query
and navigation systems through construction of the virtual potential field. Under the premise of
diffusion equation and poisson-based formula, a novel method was proposed which can
accomplish the navigation more conveniently and more efficiently. In order to guarantee the
accuracy of navigation, the relative knowledge of information transmission and the partial
differential process (diffusion equation) in electric potential field was utilized, meanwhile
gradient descent method was also applied in the process of application. A complete
mathematical derivation was used. Tiny-OS simulations show the method can efficiently
overcome the original WSNs weakness that network configuration abilities of information
navigation are not good enough. Simultaneously, during the process of explore the navigation
computation, structures of diffusion equation are more flexible and adaptability.
