The concept of ad-hoc networking merges from the need of new applications
for wireless computing technologies; which require temporary, dynamic and
self-organized network topologies.
Ad-hoc networks are a collection of cooperating nodes that are connected by
wireless links and can dynamically self-organize and communicate to form a
temporary network without necessarily using any pre-existing infrastructure. If
some of the nodes are mobile, then it is known as mobile ad-hoc network or
MANET.
Due to the special characteristic of MANETs, the routing in this kind of
networks face with some challenges. MANETs require the performance of
multi-hop routing; consequently, each node acts also as a router and forwards
packets from the other network nodes. Such multi-hop issues in mobile ad-hoc
networks is the focus of this thesis.
This research project presents the experience with real-world implementations
of mobile ad-hoc networks. Implementations of both, Better Approach To
Mobile Ad-hoc Networking (BATMAN) and Link Quality Source Routing (LQSR)
routing protocols were used. Moreover, such protocols were deployed on a test
bed based on laptops equipped with wireless cards and configured to operate
in ad-hoc mode.
Several experiments were carried out with different network topologies, mobility
models and data traffic. This research describes and analyses the results of
such experiments and it also presents a comparative study of the results
obtained for both routing protocols. |
