Hi, I want to create a node (which is a part of the wireless network)and it does not forward the packets which it receives. And how do i include this node with the other good nodes and simulate ? Please help me. Thanks in advance Subashini

[ns] Urgent: Meaning of ARP IFQ in trace file

H, I have modified AODV algorithm for wireless networks. The send request routine is working fine. The node is able to receive the request and it also generates the reply packet. But the reply packet is getting dropped and the reason i found from the trace file was that D time -2- IFQ ARP 0

[ns] Scheduler: Event UID not valid!

Hi, I have written a routing algorithm (modified AODV). I have compiled it. When i run it i get different types of errors. 1. segmentation fault. So If i change the movement of the nodes, i get 2.Scheduler: Event UID not valid! Again if i change, i get 3. check_pktCTRL : Invalid MAC

[ns] Check_pktCTRL: Invalid MAC Control subtype.

Hi, I have written a routing algorithm (modification of AODV). when i run the program, i get the error as Check_pktCTRL: Invalid MAC Control subtype. Where could be the possible location of the error?. I checked the packet formats of send routines, they are fine. I actually included the
