[ns] Queue Delay

Hello All I have a question regarding queue delay. Is there any way in NS2 to know the number of packets present in the queue of a particular node. And also how to calculate what is the time taken to empty the queue if it is full. Please let me know if any one has any idea about the above

[ns] Finding Neighbors for Mobile Node

Hi Folks A small help needed. I have a wireless network (MANET) , is there any way to know when a wireless node is actually trying to know its neighbors for transmission. Thanks -- Bhyravajosyula Sai Vishnu Kiran MS in Computer Science mail-id: sbhyr...@asu.edu

[ns] Regarding Chain Topology

Hi All A question regarding Chain Topology I have a chain topology say 1--2---3---4---5and all nodes are 240 m away from each neighbors. Transmission range = 250m and Carrier Sensing Range=550. And flows are from 122334 45 With this setup , it is being oberved that throughput

[ns] Regarding Timeslots

Hi All I need some information regarding mini-slot time and data slot time. What are the default values in ns2. I see in ns-default a value for slot-time as 20 * 10^-6 seconds. Is it mini-slot time. Thanks Bhyravajosyula Sai Vishnu Kiran MS in Computer Science mail-id: sbhyr...@asu.edu

[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
