The topology control for guaranteeing QoS requirements of nodes might not have any solution because of the limited resources of nodes, e.g., the maximum transmitting power. In this case, the mobility of nodes can compensate for the shortage of resources and then makes a topology feasible. We propose the energy efficient mobility control algorithms for the QoS topology control with the least movement. Through extensive simulations, we compare the performance of the proposed heuristic algorithms with that of the restricted distance optimal method. The simulation results show proposed algorithms make the network load uniformly distributed over the network.
