[ns] RE : Packet Drop due to Collision
dear there; first you should enable MAC trace and then from trace file you can mesure the number of packet dropped because of collision by testing the fifth column of each row of this file. when a collision is made the fifth column is set to COL. So you should calculate the number of rows containing COL in the 5th column. Regards. Goutham B [EMAIL PROTECTED] a écrit : Hello, Can someone indicate as to how do we estimate the number of packet drops because of collisions ?

Re: [ns] DSR and Segmentation Fault
Hello, Segementation faults can be difficult to track down. I once had a seg fault occurring in a class that is not even called by DSR, I finally tracked it back to a an array that i had set to size 3 but I was filling it with 15 elements or more...took me 12 hours to find the problem. So, check your code for this find of problem.

[ns] tracegraph problem with Eurane trace files
Hello, I am using the EURANE (Enhanced UMTS ...) patch for NS 2.30. While trying to open a trace file using trace graph I have an error message saying wired format detected ERROR: Cannot read the file! Trouble reading integer from file (row 25, field 8) == 0 7.0 2.0 0 0 0\n File '0 7.0 2.0 0 0 0\n' not found. A remark the tracefiles .tr in Eurane have one more additional column compared to the classical ns-2 traces (it adds a last culmun for RLC seq) Does this explain the message error? Can you provide with a solution to resolve the problem?? Regards Neila

[ns] TcpApp + Mobile Nodes
Hi Folks, I'm looking for the same functionality found in the TcpApp class for wired network to mobile environment. Reading the ns2 source code, I've verified that TcpApp class is found in the application layer, and needs the FullTcp Agent to transfer ADU (Application Level Data Unit) packets between wired nodes. Anybody knows if is there any kind of implementation of TcpApp class that will allow it to use Mobile Agents like: AODV, DSDV or DumbAgent? I'm thinking about implement it, but I don't want to if there's something like that already implemented. If I need to do this, is there anybody interested in this functionality? Best regards, M.F.

[ns] NS for Milti-interface of different radio technology.
Dear NS users, patch file/ns-extension Please advise me for the following simulation. 1. I need to simulate a multi-interface based mobile network. The interface are of different types such as WiFi, WiMAX, Bluetooth, UMTS and WLAN. 2. Is there any patch file/ns-extension for the above scenario? 3. Instead is there any generic type of patch file/ns-extension for multi-interface based mobile node simulation. Looking forward to see your kind response. Thanks in advance. Best Regards, Santos
