[ns] how to analysis the performance of routing protocols

I have simulated wireless network with 40 nodes. A node 1 is sending TCP tranffic to Node 38 which is about 600 km distance. I have tried with DSR, AODV, and DSDV routing protocol. I am interested in throughput and delay analysis. DSDV protocol is working fine and I can get the thorughput at no

[ns] how to find the SNR and BER

I am simulating Wireless network for IEEE 802.11standard. To analysis the network, I have chosen delay, througput , SNR and BER parameters. Any body can help me to calculate the SNR and BER value. One more question. Any one tell how to set the value 'd' (no of packets after which the

[ns] How to interpre the packet delay of tcp transmission

HEllo I am a new user for NS2. I am using NS2.29 . I have simulated wireless network with 2 nodes at a distance of 200m. I have generated TCP traffic frrom FTP and node0 is sending to node1. I have plotted throughput vs time. I am getting constant throughput. I also plotted delay vs packet sequenc
