Error!! str2addr:Address 35 outside range of address field length 1 !!!

MounaRM · 05-12-2011, 04:03 AM

hello every one ,

I am working on implementing a protocol on NS2.34 .
I really need help to solve this problem

. Actually , I don't now whether the problem is generated by the tcl code or the c++ code

when I run the simulation, I get this result :

Code:

num_nodes is set 64
INITIALIZE THE LIST xListHead
34
45
channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5,  distCST_ = 550.0
SORTING LISTS ...DONE!
 envoie une fourmis au noeud 45
lauching packet at 10
one second later
15
20
30
40
printing tables (95)
Error!!
str2addr:Address 38 outside range of address field length 1

thanks in advance

Hi -

Here is the problem:

And here is the NS2 code that's generating the error:

Code:

http://linear.engmath.dal.ca/ns-2/doxygen/html/address_8cc-source.html

00067 int Address::command(int argc, const char*const* argv)
00068 {
00069         int i, c, temp=0;
00070 
00071         Tcl& tcl = Tcl::instance();
00072         if ((instance_ == 0) || (instance_ != this))
00073                 instance_ = this;
00074         if (argc == 3) {
00075                 if (strcmp(argv[1], "str2addr") == 0) {
00076                         tcl.resultf("%d", str2addr(argv[2]));
00077                         return (TCL_OK);
00078                 }
00079         }
...
00269 // Convert address in string format to binary format (int). 
00270 int Address::str2addr(const char *str) const
00271 {
00272         
00273         if (levels_ < 2) {
00274                 int tmp = atoi(str);            
00275                 if (tmp < 0)     
00276                         return (tmp);
00277                 u_int uitmp = (u_int) tmp;
00278                 if (uitmp > ((unsigned long)(1 << bpl_[1])) ) {
00279                         fprintf(stderr, "Error!!\nstr2addr:Address %u outside range of address field length %lu\n", 
00280                                 uitmp, ((unsigned long)(1<< bpl_[1])));
00281                         exit(1);
00282                 }
00283                 return tmp;
00284         }
