问题 I need to arrange 100 nodes in a hexagonal shape in my tcl script. My simulation is wireless (dsr protocol). How can I do this? Which is the best size of the grid? I thought 3000x3000. Thank you. 回答1: The simplest way is to build the network graphically .. you can use nsg tool to build the network and generate the tcl code very easily http://www.nsnam.com/2013/04/ns2-scenario-generator.html first you must determine the transition range of nodes, put required number of node-> get network size

问题 I used VBF routing, in aqua-sim. However, i noticed that the source packet never reaches the sink! and consumed energy exceed the initial energy! what is the causes for that? Here is the tcl file set opt(chan) Channel/UnderwaterChannel set opt(prop) Propagation/UnderwaterPropagation set opt(netif) Phy/UnderwaterPhy set opt(mac) Mac/UnderwaterMac/BroadcastMac set opt(ifq) Queue/DropTail/PriQueue set opt(ll) LL set opt(energy) EnergyModel set opt(txpower) 2.0 set opt(rxpower) 0.75 set opt

问题 I have a simulation of a DSR routing protocol. I have 100 nodes (from 0 to 99) and the node 0 sends packets to node 99.But in this simulation I want to modify one of the nodes, for example node 50, the node at the center of topography. Basically this node has to cheat: every time it receives a route request to node 99, it has to say that it knows the direct route to node 99, without passing through other nodes. In this way, node 0 will usually choose node 50 to send a packet to node 99: this

问题 I have installed ns2. Now on terminal, ns gives % and nam gives this error. (It is supposed to pop up an animation window). child killed: segmentation violation Also, when I did the last step i.e., ./validate, I found this at the end. validate overall report: some tests failed: How do I solve this? 回答1: The only nam version that causes 'Segmentation fault', is the nam package(s) you get from from Ubuntu or Debian : Bug report, March 2014 https://bugs.launchpad.net/ubuntu/+source/nam/+bug

问题 I need to run a NS2 simulation that the delay of a link will change during the runtime, and I use following procedure in tcl script: $ns delay $node3 $node4 $delay_time to change the delay in a link between $node3 and $node4. But it only works when it's set before the simulation starts. If I want to change the delay in a certain time, e.g. $ns at 1.0 "$ns delay $node3 $node4 10ms" It doesn't work.So how to change the delay of a link during runtime? Thanks for any help. 回答1: I have been
