[ns] Connecting agents--many to many

I am currently trying to develop a simulation in which a wireless sensor network with sleeping nodes has an ad-hoc "backbone" of nodes with a higher duty cycle to reduce latency. In order for this scenario to work, however, nodes must be able to negotiate with logical children and neighboring nod

[ns] About setting meanPktSize value in DiffServ

Dear NS users, In DiffServ scenarioes, we need to set meanPktSize to let RED calculate average queue size. If we only have one physical queue, then we can set meanPktSize to be the packet size of the traffic through that queue. My question then is, if we have multiple physical queues, say 3, t

Re: [ns] Is there a maximum queue size?

Hi, I think that it's a normal behavior. The size of a non-drop queue depends on the minimum observed inter-arrival rate and the serving capabilities of the link layer. In your case, it seems that 200 packets offers enough room/space for your incoming packets, given a saturated server, to avo

Re: [ns] URGET: How Conervt Parameters of 802.11 WLAN Card To NS2 Parameters?

Hi, NS doesn't model at 100% the real world. For example you some of the 802.11 frames (i.e management and some control frames) aren't even implemented under NS (but I know that some work is being done to provide a more accurate 802.11 implementation). This is the case too for the phys layer

[ns] Is there a maximum queue size?

This is how I am setting the size of a droptail queue: $ns queue-limit $n1 $n2 $X I am seeing behavior where for 1 <= $X <= ~180 everything works fine. If you push X to say 200, then suddenly there are no more packet drops, and there always appears to be 183-186 packets in the queue.

Re: [ns] MAC_802_11 Sendup and Senddown delay

Hi, As far as I can remember, there is already a delay Queue implementation in the ~/ns-2.2x/queue directory. This does the delay at packet level and not MAC level, so I don't know if will really fit your needs. The queue can be configured to apply a random delay too to the incoming packets.
