# Handover Management in 5G Vehicular Networks
## 5 Simulation Setup and Results
### Study of a Simulation Snapslot  
In this subsection, a simulation snapshot is studied. This snapshot was taken at a simulation time equal to 43,200 s (namely a 12 h interval), while 10 of the vehicles were monitored. Each vehicle needs to be connected to a PoA that fulfills the constraints of its services and at the same time complies with its corresponding SLA agreement. Table 2 presents the status of each monitored vehicle. Furthermore, Table 3 presents the PoAs that are available in the location of each vehicle. \begin{table}
\begin{tabular}{l l} \hline \hline
**Parameter** & **Value** \\ \hline Vehicles per SLA & SLA1: 25,933 vehicles (33.3342\%) \\   Vehicles per SLA & SLA2: 25,932 vehicles (33.3329\%) \\ \hline  & Navigation Assistance (NAV) \\  & Voice over IP (VoIP) \\ Services & Conversational Video (CV) \\  & Buffered Streaming (BS) \\  & Web Browsing (WB) \\ \hline Vehicles per velocity & Normal: 25,933 vehicles (33.3342\%) \\  & Medium: 25,932 vehicles (33.3329\%) \\  & High: 25,932 vehicles (33.3329\%) \\ \hline \hline \end{tabular}

Table 3: The networks that are available in the area of each monitored vehicle. Initially, during the HO initiation, the estimated \(Q_{u,i}\) and \(SINR_{u,i}\) values are used to obtain the user satisfaction \(S_{u,i}\) with a lookup to the Satisfaction Indicators Chart (SIC). Figure 14 presents the service weights used for the estimation of the \(Q_{u,i}\) as they are obtained from the IFANP method.
