Figure 5: (a) Average of number of vertical handover occurrences for PB, LB, DRI, and PLB. The handovers are performed by a MT during its path, for different values of waiting time constraints. Performances have been obtained over 100 simulation scenarios. (b) Average of CRBs performance for PB, LB, DRI, and PLB-VHO versus different values of waiting time parameter. Performances have been obtained over 100 simulation scenarios.
