Optimizing resources utilization in heterogeneous wireless networks

With popularity and pervasiveness increase of mobile wireless networks, combining various numbers of wireless networks becomes an important challenge. The fourth generation of wireless communications is expected to integrate a potentially large number of heterogeneous wireless technologies in what could be considered a huge step toward universal seamless access. One of the main challenges for these networks is to control the topology. Efficient topology control enhances quality of service and provides less congested cells. This paper proposes an approach to topology control for the fourth generation networks. This approach is based on periodic measurements and forced handover techniques with a control layout. A seamless protocol for forced handover techniques is also presented. Performance testing highlights the interest of such techniques.
