Internet Routing for Mobile Wireless Communication
Mobile wireless communication is becoming an increasingly important
communication mode, which challenges the suitability of most of today's
networking protocols. The current specification of IPv6 [IPv6,IPng]
effectively provides for mobility management, but its mobility management
scheme is an adaptation of MobileIP for IPv4. As a result, mobility is
not managed efficiently:
- mobility is managed above the IP layer while we feel it is an inherent
part of the attributions of the IP layer since it first deals with localizing
- the address space is organized in a way that is optimized for static
hosts and networks, not mobile;
- the solution does not scale well in the face of a wide number of hosts
roaming in the Internet;
- the protocols in charge of mobility consume too much bandwidth as seen
- routing protocols do not address mobile wireless communication issues,
which in particular include:
- potentially rapid topological changes due to mobile nodes and mobile
- varying wireless link quality concerning mobile nodes and mobile networks.
The objective of this project is therefore to develop better routing
protocols for IPv6 that:
- address the issues of mobile wireless communication; and
- allow a wide number of mobile nodes and networks; and
- make an efficient use of the bandwidth.
This project is a PhD work funded by a CIFRE grant and Centre de Recherche
de MOTOROLA Paris in partnership with INRIA.
Preparation of a simulation platform for evaluation of routing protocol
performance in a mobile wireless communication environment. This task will
add simulation modules to simulate node mobility and wireless behaviour
for the selected base simulation tool, namely [NS].
Analysis and evaluation of the performance, in a mobile wireless communication
environment, of existing routing protocols for IPv6. This task will study
the weakness of current routing protocols for IPv6 in order to identify
the potential areas of improvement.
Development of better routing protocols for IPv6. This task will research
on better routing protocols for IPv6, destined for a mobile wireless communication
environment but with consideration of implementability, protocol overheads,
resource requirements, security issues, adaptability from static to dynamic
topology, scalability with respect to the size of network, and potential
adaptation for IPv4.
Implementation of the newly developed routing protocols for further
validation and experiment.
Bibliography on IPv6, mobility in networks, wireless communications,
and all the protocols involved by routing.
