Topology control for enhanced QoS on infrastructure-less heterogeneous radio networks

The increasing popularity of mobile wireless networks and various numbers of wireless networks becomes an important challenge. The future generation of wireless networks is expected to integrate a potentially large number of heterogeneous wireless technologies in what could considered a huge step toward universal seamless access. The topology management became here one of the main challenges. Efficient topology control enhances quality of service and provide less congested cell. In this paper we propose a model to control the topology of a infrastructure-less heterogeneous wireless networks (Ad Hoc and WiMAX relay networks), this approach is based on periodic measurements and forced vertical handover techniques with a control layout. Moreover, this proposed model uses a dedicated architecture with different planes (access, communication and control). We have proposed an analytical model and simulation has been used in order to provide performances rewards.
