Abstract: In order to achieve the tradeoff between network cost and network connectivity, two heuristic algorithms for topology control, which are based on link addition and link removal, respectively, are proposed. Each link's weight in the topology optimization is calculated by employing the theory of algebraic connectivity and introducing a new topology metric for each wireless link. The proposed algorithms add or delete a link according to its weight. We conceive some cost functions for different network scenarios. Simulations show that our proposed algorithms could generate the low-cost topologies under the network connectivity constraint.
