异构无线网络节点性能与代价优化部署策略

urrent researches on node deployment strategy in heterogeneous wireless networks generally consider base stations and relay nodes separately but rarely take deployment costs into account. By building 0-1 programming models and designing an implicit enumeration algorithm, we first study the deployment strategy of Ad hoc relay nodes alone for the case of a single base station with the determined location. Then we take into account the number and location of base stations, and systemically study the deployment strategies of base stations and Ad hoc relay nodes. Simulation results show that the proposed methods are effective to achieve network requirements, while improving overall network performance and reducing infrastructure deployment costs.
