[ns] Fwd: patch for ns-2.29-allinone to use with gcc-4.x

2008-04-24 Thread Md. Atiur Rahman Siddique
Hi Gaiz n Galz, To my knowledge there are some bugs in ns-allinone-2.29 (available as http://www.isi.edu/nsnam/dist/ns-allinone-2.29.tar.gz). These bugs give rise to a number of errors in multiple phases of installation over gcc-4+ systems. These are due to mismatch in syntax for newer gcc and

Re: [ns] transmit power - does it really control transmission range?

2007-12-19 Thread Md. Atiur Rahman Siddique
Hi Sita, In my opinion you dont define threshold like that. You need to ensure: 1. The receiving node can sense the signal. 2. If multiple signal arrive at the same time the signal to noise ratio is greater its threshold. You need to set three vars or use default vals with care: RXThresh_: Rec

I dont know much but I think you can do the following: If you mean propagation delay by "delay" then the following might work: Channel set delay_ 0.01; For bandwidth, you could do Phy/WiredPhyset bandwidth_ 10e6 But I am not sure if it (WiredPhy.bandwidth_) is obsolete. I
