In this paper, we study a mobility control problem in mobile ad-hoc networks with controllable mobility. Especially, we consider mission-critical networks in which nodes have their own specific missions whose degree of satisfaction depends on the their locations as well as want to maintain a good communication quality with their neighbor nodes that also depends on their locations. Hence, in this paper, we study a joint mission and communication aware mobility control problem. We formulate the problem as a potential game and develop a distributed algorithm that converges to the Nash equilibrium. In addition, we also show that if some minor conditions are satisfied, our algorithm provides a global optimal solution that minimizes the weighted sum of costs for mission and communication.
