Hi I am working on wireless ad hoc networks. I have simple scenario in which one node is sending packets to other. I set packet size 512 bytes and interval between each packet is 0.0025. it means application layer (CBR) generate total 1/0.0025 = 400 packets in a second. Each packet is 512x8 = 4096 bits (512 bytes). It means application layer is generating 1.6384 Mbits per second. I have set, ============================ Mac/802_11 set bandwidth_ 11Mb
Mac/802_11 set PreambleLength_ 144 Mac/802_11 set PLCPHeaderLength_ 48 Mac/802_11 set PLCPDataRate 1.0e6 Mac/802_11 set dataRate_ 20M Mac/802_11 set ShortRetryLimit_ 7 Mac/802_11 set LongRetryLimit_ 4 Mac/802_11 set MinimumBandwidth_ 11mb =================================== Sending application layer is generating packets at rate of 1.6384 Mbps but receiver is getting data at rate of just 0.7 Mbps, which is very less, almost half. Interesting thing is that when I change Mac/802_11 set PLCPDataRate 1.0e6 to Mac/802_11 set PLCPDataRate 11.0e6 because I need total 11 Mbps bandwidth. this throughput increases from 0.7 to 0.8 Mbps but still not 1.6384 Mbps. would be greatly thankful to you If anybody solve my problem.
