Re: [ns] Regarding Scheduling a channel access.
Hi, Do note it is no longer 802.11 once done the below changes. Your network might crumble after the 400th packets as the queue works as FIFO, only when a packet goes out another will replace it. There are two ways to do this, 1. Open ns manual and look for mobile node schema for wireless diagram. Do see which variable places the actual packet in channel. Look for the variable in your code, put a counter there, anything above it you can trigger channel as busy. 2. Since you are testing only cbr. Can generate only 400 packets and increase the queue size to accommodate 400 packets or more. Can measure fairness while not compromising the integrity of the protocols. If like to test say 500pkts on the same network, can do the same but with queue size 500 pkts or more. It becomes like infinite queue scenario. rgds Saravanan K On Mon, Feb 4, 2013 at 11:24 PM, Sai Bhyravajosyula wrote: > Thanks for the reply. > > Rather than throughput the concept here is the fairness. > > Setup protocols : > > MAC802.11 , AODV,CBR in UDP. > > Main objective is to use a magical number in sensing or accessing the channel. > > Please let me know if you have any further questions. > > > > > On Mon, Feb 4, 2013 at 4:19 PM, Saravanan Kandasamy > wrote: >> >> Why you want to do that?

Re: [ns] Regarding Scheduling a channel access.
Thanks for the reply. Rather than throughput the concept here is the fairness. Setup protocols : MAC802.11 , AODV,CBR in UDP. Main objective is to use a magical number in sensing or accessing the channel. Please let me know if you have any further questions.

Re: [ns] Regarding Scheduling a channel access.
Why you want to do that? Aint the objective of a network is to provide as much throughput as you can? You said nothing about your setup, protocols you are using etc. Dont have the liberty to assume ourselves.

[ns] Regarding Scheduling a channel access.
Hi all I need some help. How can I make a node to access the channel a particular number of times. I mean suppose I have a number like 400 , then how can I make a node to transmit only 400 times and rest of the time in backoff. Please help me .Thanks in advance. Thanks. -- Bhyravajosyula Sai Vishnu Kiran MS in Computer Science mail-id: sbhyr...@asu.edu
