this is the table entry in ADHOC  as slide says

<destination addr, next-hop addr, destination sequence number, life_time> n

 

the following is the reverse path entry

<Destination IP Address,Source_Seq#,Hop_Count,Next Hop IP Address,Expiration time>

 

and this one is the forward path entry

<IP Address of destination, IP address of node from which the entry arrived, hop-count to destination, life-time>

 

in previous topic regarding how many table we have in ADHOC , doctor guo said that one . ere is the confusing part , first of all the table entry according to slides has 4 Entry but the reverse path part has just 5 parts itself , the other thing is that definitely we can not combine these two (reverse and forward) , so they need to have their seperate section in one table . please clearify if I am wrong . the table has 2 section , one for reverse path one for forwarding path ?

Thanks

both  reverse path entry and forward path entry are entries in the routing table and they should follow the same format.

the following is the reverse path entry

<Destination IP Address,Source_Seq#,Hop_Count,Next Hop IP Address,Expiration time>

 

here, the destination IP address should be source address

and this one is the forward path entry

<IP Address of destination, IP address of node from which the entry arrived, hop-count to destination, life-time>

destination sequence # should also be a part of the entry.
