[ns] AODV using Queue/DropTail/PriQueue versus DSR using CMUPriQueue

Hi every body, When using AODV , interface queue type is CMUPriQueue, no. of node 10; the Segmentation Core dumped occured. But when using DSR, interface queue type is MUPriQueue, no.of node 10, then it simulates sucessfully. Therefore I have code my tcl script to use different interface queq

Dear All, In the case of collision over a network, how can we find a reference to the current node? or how can we know if the colliding node is the current node or not? Thanks.

[ns] Howto calculate CR distance out of RxThreshold

Hi! I need to calculate the communication range in meters, based on the CRTreshold, the Antenna Gain and the Antenna heights which are set in the TCL scripts. The Propagation model is always Two-ray-Ground. I have tried to reverse the function which is given in threshold.cc (which can be used to

Re: [ns] how do we define source and destination nodes in adhoc networks

Hi, You just need to do from your c++ code: Packet *pk = Packet::alloc(); struct hdr_cmn *chpk = HDR_CMN(pk); struct hdr_ip *ihpk = HDR_IP(pk); chpk->addr_type() = NS_AF_INET; ihpk->daddr() = dest; // the addr of the destination node ihpk->saddr() = my_index; //cur

[ns] Same or different results after running the same script?

Dear ns-users, You may be surprised of my question. I have been simulating sensor networks. I kept all parameters the same and did the second and the third run, then ns-2 gave me the exactly same results (number of received packets at the sink). Is that odd? I assume ns-2 will give me the diff

[ns] Needed help in TORA Simulation

HI friends, I want to calculate the performance of AODV, DSDV,DSR and TORA routing algorithms. But i am unable to use TORA in my simulation. If anybody sends a tcl file which used it, will be very helpful for me. Please give me some hints, how to use TORA. T

[ns] Simulating an Ethernet ring...

Hello all, I'd be grateful for some advice on the best way to simulate an Ethernet-based ring topology in ns-2. In this context, I'm not quite clear on how to disable network and transport layer functionality in ns-2 with regard to routing and packetization. I've looked at the LAN simulation capa

[ns] Overhearing Collision

Hi, I really need your help in this, during simulation, the MAC_STATE will be changed to MAC_COLL if a receiving node detects collision. what I need to know is, how can the other nodes know about the collision. and how can I distinguish between the colliding nodes and any other node. please h

Re: [ns] Needed help in TORA Simulation

First of all, what version of NS are you using? if it is before NS2.26, TORA should be OK, otherwise, you have to insert the following code into command function in tora.cc so that tora can work: int TORA::command(int argc, const char*const* argv) { . if(argc == 2) { . else if (strcmp(
