[ns] modified random waypoint model patch/script
Good day to all, i want t know if anyone have tried using modified random waypoint model in their simulation, i know some of the papers that desribe this, but seems that i can't fond any patch or script for this. I'm using ns2.33 and as far as i'm concern, the directory ns-2.33/indep-utils/cmu-scen-gen/setdest is an original Random Waypoint Model, but i wanna use Modified Random Waypoint Model, any helps are really appreciated, tq.

[ns] Optimal Active Route Timeout for AODV protocol
Does anyone has a finding in what is an optimal value for Active Route Timeout (ART) for AODV protocol, especially for mobile node. The default value is 3, and in Charles E. perkin (Defining an optimal Active Route Timeout for AODV protocol..), semms that agree with this value (3 seconds), but from my simulation, it's 0-4 to 0-8 seconds. Appreciate if someone has done this type of simukation to obtain optimal value of mobile node. Tq UNIVERSITY OF MALAYA - The Leader in Research Innovation

I have a problem with the patch file when i try to run this command and it said this: patch -p1 dymoum/dymoum-0.3_ported_to_ns-2.33.patch can't find file to patch at input line 4 Perhaps you used the wrong -p or --strip option?

[ns] Local Repair parameter (MIN_REPAIR_TTL, MAX_REPAIR_TTL, LOCAL_ADD_TTL)
Good day, In standard AODV RFC there are explanation on AODV local repair which stated that if link break near the destination (no further than MAX_REPAIR_TTL) and it also stated that RREQ ttl should intially set value of max(MIN_REPAIR_TTL, 0.5*#hops) + LOCAL_ADD_TTL but i seem can't find where is this parameter in the source code (i search all through aodv file). I wish to change some of this value to study the performance. Appreciate if anyone can tell me where is this parameter file location.

[ns] How many times local repair attempt?
I'm trying to calculate how many route repair attempt have been made
during simulation. I try to put a counter but it's unsuccessful
(looks like basic C++ but i failed). The source code is aodv.cc
this is my modification: #ifdef AODV_LOCAL_REPAIR
/* if the broken link is closer to the dest than source,
attempt a local repair. Otherwise, bring down the route. */
int rtrepair = 0;
if (ch-num_forwards() rt-rt_hops) {
local_rt_repair(rt, p); // local repair
rtrepair++;
// retrieve all the packets in the ifq using this link,
// queue the packets for which local repair is done,
//return;
}
else {
printf(Number of Attempt route repair : %d \n,rtrepair);
}
return;
#endif // LOCAL REPAIR
i define 'rtrepair' parameter, and if network attempt to do local
repair, it will justt increment it. Anything wrong with my code?
can i get number of route repair attempt in trace file? if yes, how?
appreciate all the ns2's sifu out there help

[ns] MaxHelloInterval and MinHelloInterval function in aodv
Hi all,
I just want to ask what does MaxHelloInterval and MinHelloInterval
really menas and do in aodv code?
It really puzzlaes me thuis code in aodv.cc from line 166 to 173:
void HelloTimer::handle(Event*) {agent-sendHello();double
interval = MinHelloInterval + ((MaxHelloInterval -
MinHelloInterval) * Random::uniform());assert(interval = 0);
Scheduler::instance().schedule(this, intr, interval); }
why the value for hello timer (i assume that's hello message
interval) is equal to MinHelloInterval +
((MaxHelloInterval - MinHelloInterval) * Random::uniform());
for the old version of ns2 (version 2.1x), it does not have these
MaxHelloInterval and MinHelloInterval
should it be as simple as HELLO_INTERVAL x ALLOWED_HELLO_LOSS?
it's defined in aodv.h from line 119 to 123:
#define HELLO_INTERVAL 1 // 1000 ms #define
ALLOWED_HELLO_LOSS 3 // packets #define
BAD_LINK_LIFETIME 3 // 3000 ms #define
MaxHelloInterval(1.25 * HELLO_INTERVAL) #define
MinHelloInterval(0.75 * HELLO_INTERVAL)
i'm not quite understand what does this MaxHelloInterval and
MinHelloInterval do, if anyone can explain to me, it will be much
appreciated..
I also have tried simulation with both AODV-LL and AODV-HELLO, and
seems that the performance is quite match (AODV-LL is better by maybe
0.1 % for high mobility scenario), for me it does not make any
sense...
is something wrong with the AODV ns-2.34 code?
