Once coverage holes appeared in wireless sensor networks( WSNs),performance of network will be severely affected. Aiming at this problem,joint patch method ,a kind of coverage hole repairing algorithm based on mobile nodes is proposed. This algorithm sewsall the needed mobile nodes into a large cloth,according to the sewing program,which is pre-established,and then repair the hole directly. Firstly,performance of the algorithm is proved theoretically,and then by using Matlab simulation; both of the number of nodes required and redundancy are compared with PATT algorithms; finally,stability of the algorithm is analyzed. Eventually,it shows that this algorithm has a higher coverage rate and lower redundancy.
