Hi all,
I have modified AODV protocol to support other routing metric than hop-count,
at the final stages of performance testing I have realized the following:
I have added new fields to RREQ and RREP packets, lets say I have added three
quantities of type double (x, y, z) to the RREQ to allow intermediate nodes to
calculate the new route metric. What I have realized that the protocol
performance will be different for the following two cases:
-- if I have added these values as an array to the RREQ header (i.e.double
new_metric[3]),
-- if I add them as a three elements (i.e. double x, double y, double z).
Also if only one element of the array is filled (i.e. new_metric[0], for
example) the performance will be different from having all array elements are
filled.
I am measuring the total network throughput, the results are different for
different RREQ format elements arrangements.
Can any body explain this to me? what is happening here?
Thanks,
Ghada
