A MANET Mobile Ad Hoc Nettverk, is a network consisting of mobile nodes,usually comunicating through radio links.In a MANET it may be that data have to take the path through one or more nodes to reach its destination.
Today broadcasting in MANETs is normally done by having routing daemons in the application layer,retransmitting the traffic that is to be broadcasted.In this thesis you will be presented to an alternative solution, pushing this functionality down the IP stack to the IP layer.The broadcasting is suggested to be done by IP flooding.
An implementation of the functionality is done for the Linux kernel (version 2.4).It is presented in this thesis.You will therefore meet a lot of details from the implementation of both Linux and a routing daemon (unik-olsrd-0.4.0).
The implementation, called flooder, is in an very early fase of development,and therefore it has not yet undergone thouroughly testing.A simple test is included anyway, as a proof of consept.
One of the routing protocols dedicated to MANETs, is called OLSR (Optimized Link State Routing).It is put forward a suggestion, how to modify OLSR, taking advantage of the functionality of flooder. Plans and ideas for further work is also put forward.
