[ns] Number of neighbours
Hi all,
How can I know the number of neighbours a node has before sending a packet. I
am
using the Agent below. When recieving, the node brodcast the packet with a
probability. I need to know the number of neighbours to make that probability
dynamic. In other words, when recieving a packet, the probability of
rebroadcasting will be higher if there will be fewer neighbours.
Thanks a lot.

[ns] port of agent in multicast
Hi all: I have a problem about the port of Agent. I have two Agent,one is a sender, another is a receiver. I set dst_port_ of sender=x. I get the value of agent_port_ of receiver is 2. Whatever the x is,the simulation will go on all the same in the multicast. Why does it happen? How can I fix it? Thank you very much! Balbo.
[ns] How to congest a node to make delay packets forwarding?
Hi Guys I really need help in this one. I am unable to simulated a congested network. I keep increasing the packets sent from node A to node B but I see always my packets that are going from source to a destination (who sits on path A-->B) to arrive at the same time. I expect them to arrive later as node is being congested with packets but no luck Any help/ideas how to solve this? Can I increase the packet processing time at a node? or how can I get around this please help, I just need to prove that packets are delayed as we are congesting a node sitting on the path.
