wireless multicast tree construction

[Rasoul Behravesh]

 

hello everyone, 

i use Inetmanet framework

i have several mesh node 

this is description of my network:

8 wireless router 

each router has 3 wireless NIC Ieee80211.b/g

each wireless NIC of a node works on different channel 

My Question:

i want to construct a multicast tree among this nodes I think for multicast tree construction in wireless mesh networks  I have to manipulate the routing table of each node. Am I right? If so, can I change routing table dynamically? Using which statements i can access and manipulate the routing table of individual nodes in a central node(centralized) ??.  How can a node send an incoming packet to just its next hops ??

thanks in advance 

regard,

To manipulate the routing table dynamically use addRoute/deleteRoute from the IRoutingTable class:

https://omnetpp.org/doc/inet/api-current/doxy/class_i_routing_table.html

You can check the inet manetrouting protocols to see how to do it.

And to change them from a central node, you can use direct calls as explained in:

https://omnetpp.org/doc/omnetpp/manual/usman.html#sec182

To send a packet to just its next hop, you can use a TTL=1.

Cheers,

Ester
