getorigin from rerr aodv

[Lincy Elizebeth Jim]

hi all

I am using ns-3.23

for aodv-packet.h in the class Rerr

i added  void SetOrigin (Ipv4Address a) { m_origin = a; }

Ipv4Address GetOrigin () const { return m_origin; }

and also IPv4Address m_orign as private

in aodv.packet.cc

RerrHeader::RerrHeader (Ipv4Address origin) :

  m_flag (0), m_reserved (0), m_origin (origin) {

 }

In void RerrHeader::Serialize

i included WriteTo (i, m_origin); along with the other lines of code

In void RerrrHeader::Deserialize

I included ReadFrom (i, m_origin); along with the other lines of code

i am getting you have attempted to read a value smaller than buffer size

kindly guide

thanking in advance

Today you're going to make me mad.

We discussed this point countless times already. You added a field in an header and you didn't modify the serialized size accordingly.

Hi

I did modify RerrHeader::GetSerializedSize
const {
return (4+8*GetDestCount ());
}

Kindly guide

The original RERR serialized size is:

uint32_t
RerrHeader::GetSerializedSize () const
{
  return (3 + 8 * GetDestCount ());
}

You did increase it by one byte.

Do you think that an IPv4 address is ONE BYTE long ?

Explain.
