A movement control algorithm is presented to improve the performance of mobile Ad Hoc networks on condition that positions are unavailable for nodes. The algorithm proposes a way to move the mobile nodes to the optimal position, only according to the detected signal strength. Beginning with the definition of the performance function, the article then proves that the moving target can be fixed at the point with the optimal solution of the function. The algorithm leads the mobile node into the optimal location from anywhere it stays. Finally, the simulation results show that the newly designed movement algorithm can be used to seek out the optimal point, and meanwhile minimize the transmission cost by moving the node to this point.
