[ns] wireless trace
Hi everybody, I have several questions about the 802.11 model. I would really appreciate any help. I want to run the wireless simulations in infrastructure mode. That is, all the packets should go through AP. Is it enough if I turn Routing to dumbAgent? Also, is there any way to get information about the type of MAC packet (RTS, CTS, DATA, ACK) etc. printed in the trace? Also, what does it mean to have a -Hd value of -1 (as seen in the line below) s -t 0.036705082 -Hs 2 -Hd -1 -Ni 2 -Nx 6.00 -Ny 6.00 -Nz 0.00 -Ne -1.00 -Nl MAC -Nw --- -Ma 65 -Md 0 -Ms 2 -Mt 800 -Is 2.255 -Id -1.255 -It message -Il 70 -If 0 -Ii 1 -Iv 32 Thanks, Arvind

Hi Atiur,
It was my mistake. I made some mistake while copying it to linux.

Re: [ns] transmit power - does it really control transmission range?
The transmission range depends on the transmitted power, propagation model and recv thershold. So, yes, I think all the nodes are not connnect with these values. -Atiur --- "Sita S.

[ns] meaning about seed????
1. I have simple question What is definition about seed, and what different effect if we use seed =0.25 / seed =1.0 2. if we have 2 wired destination, 2 router how to calcullate the receives number if we send packets from wireless node to wired node. I was calcullate this value with set ($4=="0" || $4=="1"|| $=="2" || $4=="3") but give me PDF/delivery ratio over 100% what can I do suppose me please.
