Re: [ns] for transmission power

2010-11-24 Thread alizey Khan

Dear Dhara,


To let the packet sent by N1 be received by N2, u need to adjust the values of 
Pt_ and RxThresh_ depending upon the distance between the two nodes. U can get 
the value of RxThresh_ using a utility shipped with NS2 in a folder named as 
indep_utils and the utility name is threshold.cc. Refere to some ns tutorial 
for 
its usage.
As far as value of Pt_ is concerned, i myself is looking for it i.e. how to 
compute its value for certain distance (SO if u get to know from somewhere how 
to compute that, do letme know too).

By default in NS2, communication range of nodes is 250m and the corresponding 
values for Pt_ and RxThresh_ are 0.2818W and 3.625e-10W respectively.

Goodluck!

Hello,
   I want to create a wormhole link. For that, two nodes N1 and N2 have been 
positioned far away from each other. What transmission and receiver power or 
some other properties do I need to set for making the packet sent by N1 to 
reach 

at N2?
  Thank You,

[ns] Setting transmitting range of nodes

2010-11-14 Thread alizey Khan

Hello All,

I have to deploy a network comprising of 2 type of nodes: one with lower 
comunication range e.g. 50m and other with range 500m. As far as i think, i 
need 
to adjust both RXThresh_ and Pt_ values for both type of nodes. But i found 
following post on web regarding my issue:

Usually you define Pt_, RXTresh and then compute the maximum possible 
transmission range. But if you need a different range you set it fix and 
compute either Pt_ or RXTresh while keeping the other fix. 

For a longer distance you need either a higher Pt_ (stronger sender) or lower 
RXTresh (more sensitive receiver).

Any Comment? 



  


[ns] (A naive solution) how to set different transmit range for different node

2010-11-13 Thread alizey Khan

Hi All,

I URGENTLY needs to get some Pt_ values for certain  distances. I saw a post 
with the title [ns] (A naive solution) how to  set different transmit range 
for different node with a reply that  phenix has modified threshold.cc to 
get 
Pt_values. But there was no attachment with the message.

Can i get that..
I need in a bit urgency
ANy help will be welcomed
