[ns] TKN 802.11e with RTS/CTS

Hi ns-useres, I would like to know how can I add RTS/CTS to the TKN 802.11e model for NS2_26. I've tried by setting RTSTHhereshold_ 0, but my simulation abort telling me something like: (0) RECEIVING DATA!!! (0) RECEIVING DATA!!! (0) RECEIVING DATA!!! ... I really need to know if it

[ns] TKN 802.11e model and RTS/CTS

Dear NS-users, I'd like to know if it is possible to add RTS/CTS to the TKN model of 802.11e for NS 2.26. If it is possible, what do I have to do? Thank you very much, Michele

[ns] Dropping Packets with RTR CBK

Hi ns users, does anybody know what does it mean when a TCP packet is dropped and in the trace file is indicated as RTR CBK? Thanks a lot, Michele Nuti

[ns] RTR CBK

Hi NS users, I'd like to know what does it mean in the trace file this thing: D 12.020142136 _5_ RTR CBK 981 tcp 1500 [13a 1 0 800] --- [0:2 4194305:1 28 4194305] [494 0] 0 0 RTR CBK what kind of drop is? It happens when the Access Point try to send in the wireless channell a high bit

[ns] RTT: how it works?

Dear NS users, I'd like to understand how ns calculate the rtt in a TCP connection. What the rtt_ variable state trace? It is the delay of the TCP packets + = the delay of the ACK packets? And it is expressed in s, ms Please help me. Thank you very much. Michele Nuti

[ns] Scheduler: Event UID not valid! without RTS/CTS

Hi NS users, I remove RTS/CTS from MAC 802.11 (setting RTSThresh_ 3000) and now I often (but not always) receive this message: Scheduler: Event UID not valid! and the simulation stop. Does anybody knows why and how to solve the problem? Thanks a lot, Michele

Hi Ns users, does anybody if it is possible and how to disable the RTS/CTS in MAC 802.11? Thanks a lot, Michele Nuti

[ns] Throughput in TKN 802.11e

Hi NS users, I have a question about Throughput in 802.11e model of TKN. Why if I set a TCP flow with lower priority (prio_ 3) in 802.11e MAC it has a higher throughput of the same flow with 802.11 MAC? I think that the throughput should improve only with high priority (0, 1, 2)... Thank

[ns] TKN 802.11e and Wireless Channell Error Model

Hi NS users, I have a problem with 802.11e Model of TKN of Berlin. If I set an Error Model for the wireless channel using Mac 802.11e, no one packet is dropped in the trace file. If I use the same simulation just changing MAC 802.11e with MAC 802.11 I see that some packet get lost in the

[ns] Handover: 2 or more Access Points

Hi, I would like to simulate a wired cum wireless scenario with 2 or more access points: what do I have to add to the tcl file to make the handover possible? Thanks a lot, Michele

[ns] Pareto distribution problem in wireless scenario

Hi, I've noted that in NS version 2.26, the Pareto distribution only works = in wired scenarios, but not in wireless scenarios. Does anybody knows why and how to solve the problem? Thanks a lot, Michele
