Hello everyone,
I am trying to implement a star topology using MAC/PHY 802.15.4 in non-enabled
beacon mode. I am using wpan_demo2.tcl and trying to do some changes to the
original. To set the beacon mode of I have done the following:
$ns_ at 0.0 "$node_(0) NodeLabel PAN Coor"
$ns_ at 0.0 "$node_(0) sscs startPANCoord 0 3 3" ;# startPANCoord <txBeacon=0>
<BO=3> <SO=3>
$ns_ at 0.5 "$node_(1) sscs startDevice 0 1 0" ;# startDevice <isFFD=1>
<assoPermit=1> <txBeacon=0> <BO=3> <SO=3>
$ns_ at 1.5 "$node_(2) sscs startDevice 0 1 0"
$ns_ at 2.5 "$node_(3) sscs startDevice 0 1 0"
$ns_ at 3.5 "$node_(4) sscs startDevice 0 1 0"
$ns_ at 4.5 "$node_(5) sscs startDevice 0 1 0"
$ns_ at 5.5 "$node_(6) sscs startDevice 0 1 0"
In the trace file i get the following (just a part of the file of course):
s 0.002560000 _0_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
r 0.003008033 _3_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
r 0.003008033 _1_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
r 0.003008033 _4_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
r 0.003008033 _6_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
r 0.003008033 _2_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
r 0.003008033 _5_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
s 0.141760000 _0_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
s 0.281920000 _0_ MAC --- 0 CM7 8 [0 ffffffff 0 0]
s 0.500640000 _1_ MAC --- 0 CM7 8 [0 ffffffff 1 0]
r 0.501088033 _2_ MAC --- 0 CM7 8 [0 ffffffff 1 0]
r 0.501088033 _0_ MAC --- 0 CM7 8 [0 ffffffff 1 0]
r 0.501088033 _6_ MAC --- 0 CM7 8 [0 ffffffff 1 0]
s 0.501408033 _0_ MAC --- 0 BCN 11 [0 1 0 0]
Meaning that all the nodes are sending and receiving beacon requests (CM7) and
node 0 sends beacons (BCN) but no other node recieves them. What am I doing
wrong? I don't want any node to be sending beacons or beacon requests! Your
help would mean a lot to me cause this is giving me a terrible headache!
Thanks in advance!!!
