Hi Nadine, One way to reduce the number of neighbors is to reduce the average node density. For example, you have a network of 100 nodes, then you can control the number of nodes, let's say each node can have 10 neighbors or each node can have 20 neighbors. To achieve this, you can vary the grid

Re: [ns] how to forward packets based on probability

Hi Phenix, To forward a packet with certain probability, you need to include an if condition in the sendPkt() function. It should be something like this: If(probability > 0.5) { Scheduler::instance().schedule(target_, p, delay); } in the SendPkt() function. Hope it helps Regards Mubashir www

Re: [ns] printf doesn't work in aodv.cc file

Hi Domenico, Basically you need to uncomment some lines, in order to enable Hello Packets. Then and only then program pointer will come to recvHello() and sendHello() functions. If you want to broadcast Hello messages then, you should do the following: Comment the following two lines in aodv.cc

Re: [ns] Capturing Packets

Hi Sri Charan, Yes it is possible. You need to work in the recv() packet function and dump the contents of all the packet in the trace file. Regards Mubashir Husain Rehmani ASAP/INRIA and LIP6, UPMC www-rp.lip6.fr/~rehmani http://www.irisa.fr/asap/Members/mreh

Re: [ns] Walls and structure in ns-2

Hi Faraz I just want to share you a trick that you can use to simulate walls and roofs with different physical channel characteristics. Walls and structures impacts over the channel physical characteristics. It means that if you have two rooms with two different antennas, the overall impact will

Re: [ns] Energy consumption for mobile nodes not receiving/transmitting

Hi Salvo, Yes, it is normal. For instance there are 10 nodes that are within the range of each other. If node 1 sends packet to node 10, then all the nodes overhear the packet, and discard the packet (because the packet is not destined to it). Thus, it is obvious that, in this case, nodes will co
