[ns] Timer with packet ID

2006-07-11 Thread sandoche balakrichenan
Hello everybody The timer function in NS in Constant Bit Rate(CBR) traffic generation works like this. After every interval it creates a new packet and sends the created packet. For me what i want is, if i have created a packet with sequence number 1, i send that packet and wait for

[ns] AODV in ns-2.26 ?

2006-07-11 Thread erwin budi
hello, I have simulated wired-cum-and-wireless with ns-2.26 on Red Hat 9. In opt(adhocRouting) i use AODV.But when i simulated it,it can't work well.Packets didn't send to MN.But when i change into DSDV it can work.Do ns-2.26 doesn't support for AODV?or are there any false with my script.Thanks

[ns] 802.11 dynamic bit rate change

2006-07-11 Thread guille
Hi, In real 802.11b and 802.11g wireless cards the bit rate changes dynamically depending on the channel conditions. If the card is working at 54Mbps and is receiving no ACK's from the receiver it will automatically switch to a lower bit rate. Modulations used by lower bit rates are stronger

Hi Christos, Hi all, I noticed also that TCP behaviour is different between the two versions (ns-2.26 ns-2.28). I ran the same simulation on both versions and I noticed that in ns-2.26 there is more dropped packet than in ns-2.28. I do not know if this is a bug in ns-2.26 or not. Has any

Hi ns-users, I have a question related to the receive function in dsdv.cc If you take a look on the code it does the following: 1- It first checks if the node is the sender (src == myaddr_) 2- Then it checks if the packet received is a routing packet (src != myaddr_) (iph-dport() == ROUTER_PORT)
