A Cross-Layer Location-Based Approach for Mobile-Controlled Connectivity

The authors investigate into the potentiality of an enhanced Power and Location-Based Vertical HandOver (PLB-VHO) approach, based on a combination of physical parameters (i.e., location and power attenuation information), for mobile-controlled connectivity across UMTS and WLAN networks. They show that the location information in a multiparameter vertical handover can significantly enhance communication performance. In the presented approach a power attenuation map for the visited area is built and kept updated by exploiting the information sharing of power measurements with other cooperating mobile devices inside the visited networks.
