Adding a new field to the hello msg

[Doaa]

Hi all

I would like to add a new field in the Hello message called "qos" to add a specific value in it that will be used later for the route selection. So I should modify the header of the message. I read this useful link  https://www.nsnam.org/support/faq/miscellaneous/#adding-data-to-an-existing-packet that shows how to add new header to a packet. The problem that I am facing that I dont know how to add this field in the packet since there are already fields in it (willingness,htime,...etc).  So how can I add this field without affecting the other fields? 

please share any suggestion or a useful link. 

Thanks in advance

Hi Doaa,

You would have to modify the existing header (since the HELLO message is in principle a header) and add your field.

This entitles modifying the Serialize, Deserialize and GetSerializedSize methods.
