[ns] broadcast message
[URGENT Help needed] Hi . I have a set of wireless(802.11) nodes in my ns2 and also each node has a unique message (consider it a string of about 20 to 40 characters) . Now I want each node to broadcast its message, and when a node is within broadcast range of another node , it should receive the broadcasted message of that node . I will then change the message in each node and re-broadcast . I do not care about the underlying concepts such as dividing the message into packets or trasmitting/recieving the packets, collisions, etc..., for me sending and receiving the message is important, I just want it to be like a realistic 802.11(wi-fi) broadcast . Is this possible in NS2 ? If so how ? Thank you in advance .
[ns] olsr- how to dump all routing tables
Hello, Have anyone sucessfully dumped the routing tables using OLSR? I see a function for that in the c++ class, but couldn't find how to use it through NS-2 tcl script. Thanks in advance. -- Érico V. Porto
[ns] TCP send and receive?
Hi , I'm doing research on TCP wired model. Can anyone tell me what is the function responsible for sending packets in TCP and receiving ? I found many for sending in TCP.cc file. However, it seems the one responsible for sending in agent.cc? Thank you in advance Regards, Mohd.
[ns] Routing Problem
Hello, I have a problem with routing in NS2.29. I need to force the communication between two nodes. I have a configuration like thisBS - node 1 - node 2 - node 3 - node 4. I dont care if BS communicates directly with node 1, node 2 or node 4, but i want to make it that when node 2 receives signal from BS, it sends the received packet to node 3 always. If I change next_hop in the C++ code, what would happen? Ns2 recalculate the route? it will crash or loss the packet? There is a way to make manually this transmission between node2-node3 using a DSDV or AODV routing algorithm for the rest of the transmission? Can I use hierarchical routing just for this step of the transmission? Help will be appreciated. Bye.
[ns] Controlling Energy and Session
Dear NS2 users, Had an urgent question. How can I setup a session in ns2 such that: If nodes are divided into different energy classes; say E1,E2,E3 and so on and E1E2E3. I want to convey the energy class to the neighbors since the logic is key to enforcing routing decisions. What will I have to do to make this change? Thanks and Best Regards. Anoop
