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

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
