%X <p>To solve the resource optimization problem in self-organized heterogeneous networks,a resource configuration scheme is proposed. The novel scheme takes energy efficiency and connection stability of the network into account. This scheme includes three steps. Firstly,obtain the available channel resource through exploiting surrounding environment and then put the channels into the spectrum pool. Secondly,design user selection method on the basis of Morse potential which can guarantee network connectivity and reduce the transmission power cost. Finally,utilizing the results from the two former two steps,allocate proper power level to users while optimizing network energy efficiency. In the step of user selection,users are sorted according to the Morse potential and the ones with smaller morse potential value are selected and served with high priority. Power allocation is achieved by Barrier method. Simulation results show the advantage of the proposed scheme which can save transmission cost,guarantee stable network connectivity and gain higher energy efficiency.</p>
