Due to the spread of mobile applications and development of the quality of wireless data distribution, new radio access technologies (Wi-Fi, WiMax, 3G, 4G/LTE) have appeared. Though these solutions are heterogenous at the physical layer, all of them uses IP to communicate at the network layer.
Network-developing follows the All-IP trend nowadays, therefore the possibilites of implementation should be concerned regarding to mobility handling. The Mobile IPv6 – extending the Internet Protocol version 6 - gives a solution to these problems. Though this standard is capable of serving moving users, its behaviour is suboptimal in many situations.
In my thesis, a introduce and examine Hierarchical Mobile IPv6, which reduces the time of connection-loss caused by handover, and the Mobile IPv6 Fast Handovers standard, which describes how to tunnel incoming packets during handovers.
Measurements showed that it is worth examining these extensions, and even further developing them. A perfect example of it is Integrated FHMIPv6, which integrates the two mentioned protocols in the hope that this way the throughput of the network grow even more. While examining the Integrated FHMIPv6, I experienced nearly perfect, close to zero percent packetloss.
Mobile IPv6 has even more extensions, that are worth dealing with, measuring their performance and combining them with each other in the hope of optimal results, therefore this area hiddens a lot more possibilities in itself.
