Re: [ns] multi channel multi interface for 802.11 by Prof. Ramon
Hi All, The problem of NULL handler was occuring due to the forward method. In this method Iface is not defined. If we define it in the method then it gives the error mentioned. I replaced the Iface with rt_interface and it worked without error. Prof Ramon, Please correct me if I am wrong.

[ns] Multichannel in NS2
Dear Friends, I tried a scenario with 4 wireless nodes communicating as shown (using same channel) 1 2 ch1 3-4 Now when I assign different channels (i.e. ch 1 and ch 2) to these I do get a good throughput as expected. My doubt is, in NS2 when we set the channels, what frequency does it map to? Where can I look for this mapping in NS2 code (I am not able to locate the same) Plz help !

[ns] WiFi infrastructure and MEsh
Hi all, Can anyone help me by suggesting how to simulate a node which can communicate via hops within its own circle of nodes and for communication to other circle it uses its AP-AP of other circle.

[ns] RTR - IFQ Problem
Hi all, Can anyone help me to understand why most of the packets drops at RTR -IFQ level. I tried to simulate around 200 nodes - 1000 nodes for 802.11 and realized that most of the packets are dropped. I changed the queue size (ifqLen) but that didnt give any improvement.

[ns] wireless nodes Ns2
Hi All, I need help in simulating around 1000 nodes in 3000X3000 area. But when I run the simulation it works only to a maximum of 300 nodes. If I increase the number of nodes to say 400 , it gives segmentation error. I am using wireless 802.11 module for it. Thanks Regards Kiran
