Abstract
QoS and mobility is a field that still has some performance issues.

QoS degrade when IP based nodes become mobile. This thesis tries to

make IP based networks as good as cellular networks, when it comes to

mobility.

We focus on solving the added complexity introduced by QoS in mobility

management in the middleware layer, inside a remote binding.

The main problem states, that we should find out how a remote binding

can adapt and enhance QoS-parameters that perform poorly in IP based

mobility management.

The methods used are testing and prototyping. We test existing

mobility management software (Mobile IP based) and design, implement

and test a QoS-Aware Remote Binding, named MobiBind. A custom traffic

generator, KGen, was developed as part of this thesis, in order to

performe testing.

In the test of Mobile IP, we found that the QoS parameters; packet loss and seamlessness underperformed. We also found that hand-overs in IP based mobility takes about one second to complete.

MobiBind did manage to increase performance of both packet loss and

seamlessness in mobility management. This did however increase the

delay (round trip time).

We found that the main problem in mobility management is the

hand-overs, and the connection breakage of about one second. This

introduces QoS degeneration that in our Mobile IP tests showed up in

the QoS parameters packet loss and seamlessness. MobiBind increased

performance of these QoS parameters, at the cost of delay. This

indicates that there is a tradeoff between the different QoS

parameters, and that total QoS might be difficult to increase unless

the underlying problem is fixed, in this case; the connection

breakage. MobiBind enables application developers to control which

QoS parameters mobility management impacts.
