**4.3 Conclusions**

This research shows the effects of the FHAMIP/AODV integration over the QoS metrics. The simulation proved that the average delay was approximately 112,27 ms and was penalized by the AODV signalling, so it was necessary to update the status of the routes. On the other hand, the average jitter analysed reached 38 ms.

Regarding the loss of packets, a total of 86 did not reach the destination. Most of them were lost when the AMN moved either towards the APAR or to the ANAR.

The jitter was quite satisfactory given the fact that it exceeds 176 Kbps. In general, the delay and the jitter suffer the strong effects of the AODV routing updates. Some nodes stop sending TCP packets to transmit useful AODV signalling to recalculate routes, increasing the delay in a TCP session significantly. A possible solution (assuming that only a node moves on) would be to modify AODV in order to stop routes updating until the APAR and the ANAR receive a MAP\_REG\_REQUEST from the AMN. This would indicate that the AMN is in its own area.
