Hello all,
I am doing postgraduate in Computer Science. I am doing my project in
wireless
sensor network. I do my project based on the clustering protocol. So, I
follow
the LEACH protocol as the base one.

Regarding to that i downloaded the ns2.1b5 allinone package from net (ns2
homepage) and also downloaded the MIT uAMPS changes (LEACH extension) to
ns2.1b5.

Now i have a problem in running the LEACH code. Actually i installed the
ns2.1b5 package in Redhat linux 7.2 in celeron 466MHz system. After
installation i try to add the LEACH extension code to the ns2.1b5.

After addition i try to recompile the ns2.1b5 package and while doing so i
get
the following error:

I verified the packet.h and ns-packet.tcl files and everything is perfect
about
the structure hdr_rca. Even then i am getting the above mentioned error. So

kindly request you to help me in clearing this error as soon as possible.
