In adaptive mobile network like battle fields or military applications, the base station configuration may change dynamically. Mobile nodes communicate via a base station and can move freely. This dynamic change together with the constraints make the assignment of mobile nodes to base stations difficult. In this paper, we propose the polynomial-time algorithms to find a good partitioning of mobile node assignment. We also show that the assignment of mobile nodes to base stations under bandwidth and communication constraints is NP-complete. We propose two graph models to represent mobile node communication requirement as well as base station configuration. Our simulation results show that our techniques can efficiently give a good performance close to the exhaustive approaches which minimize the frequency of a node that is not covered by a base station in the dynamic environment.
