Hi all, Could anyone tell me how to calculate routing overhead of DSR? How about the header size of RTR ( DSR ) and MAC (802.11) ?

" According to the output trace file, the rtr layer header is 30-10=20 bytes (how the header size got, is it the DSR routing header?),and the mac layer header is 82-30=52bytes(PHY +MAC header). But why it transmit 82 bytes only receive 30 bytes? How much is the biggest header size of DSR routing protocol using in RTR layer because I find the value of the playload in RTR is variable, not always 20bytes? I uesed the CBR / UDP, the packet size is 10 bytes. (if need consider the IP/UDP/RTP header, the packet size should add 40 bytes ?) Regards, HuiYao
