Optimized deployment of wireless sensor networks（ WSNs） can improve lifetime of network

and enhance reliability of system. Aiming at problem of coverage of sensor nodes

propose a new type of virtual force leapfrog strategy

using factors of attraction and repulsion of virtual force algorithm

to optimize the optimal solution of groups and memes group in leapfrog algorithm

and make leapfrog algorithm quickly jump out of local minima

and then search globally. Analysis and simulation results both demonstrate that this strategy can optimize deployment of sensor network rapidly

has good convergence and coverage rate

which is more close to the theoretical value.
