[ns] Wimax simulation problem
Hi, I am using the NIST module for wimax simulations. When i send a packet to or from a subscriber station the packet is split in two parts. Does anyone no how to disable this? George.
[ns] simulation work.
Hello i Hope this mail of mine will find you in best of health. i generate the tcl script for the following scenarion. 2 4 0 3 1 the above figure is the position of the nodes. all the nodes are in transmission range of each other. The problems starts as whenever there is packet exchange(RTS/CTS, Data, ACK) between the nodes, they will hear each other. supposing we want to calculate the available bandiwdth for node 0 which is not transmitting.the traffic generated by other nodes act as backgoroud traffic for it. now we are sending the traffic from 2 to 3. When ever the packets is exachaged between the nodes mentioned above, node 0 will hear it. Subsequently it need to get (and save) the value for duration/id field which will acts as NAV. the question is how can we simultaneously know which node number packet we are hearing and store the NAV value corresponding to that node number. also whenver the ack packets are sent from node 3 where can i find its NAV value.for every sucessful transmission of packets(RTS/CTS, Data, ACK) we have to store the value of NAV in buffer of node 0. to start with we are just! considering the data transmission between node 2 and node 3. the situation become complex as the number of node competing for the traffic increases. what we require is the following table Time period Node number/IP address NAV VAlue Transmission(sucess/not) kindly send in me useful inputs.

[ns] setting the parameters
Hi all i simulating a paper for my work to start with. I need to set the following parameters for the simulation MAC Header (bytes) : 34 PHY Header (bytes) : 16 ACK (bytes) : 30 how will following parameters be given. Anyhow if we dont chage the structure in 802_11.h what is size of the above parameters. Neeraj Gupta Assistant Professor HOD, CSE IT Department Hindu College of Engineering Sonepat
[ns] Tcl code for communication between 2 wirless node.
Hi all; i need a tcl code of communication between 2 nodes. Mac/802.11 tcpSink - xtcp n0 n1 n2 n0 is a mobile and n1 is a base station n2 is the source and n0 the receiver. Please it's urgent Thank you.
[ns] Question regarading to implementing protocols in ns
Hi everybody I'm a new user in ns! I'm looking for implementing some protocols, actually 802.1AB (Link Layer Discovery Protocol) in Layer 2 and also SIP in application layer in ns-2. Do you know that these protocols are implemented before and if they are, would you point me the codes. Bests Saeideh Carleton U, Ottawa, Canada
