23 // Default network topology includes a base station (BS) and some number of
24 // subscriber station (SS) specified by the variable nbSS (defaults to six).
25 // The SSs are grouped into two groups: senders and receivers. SSs from 0 to
26 // nbSS/2 are designed as senders and SSs from (nbSS/2 + 1) to nbSS-1 will
27 // designed as receivers.
28 //  each SS creates 3 transport connection with the BS. the fist one has as QoS
29 // scheduling type UGS, the second one rtPS and the third one BE.
30 // Senders SSs send some stamped IP packets with variable bitrate to receiver SSs
31 // through the BS station. receiver SSs receive the IP packets analyze them and
32 // based on a sequnece number decide if all the packets are coorectly received
