Algorithm 1

Flooding avoidance.
Begin
Foreach (received request) Do
 If (source_ID of the request in Request_Counter table) Then
  Increment request_counter of that node;
End if
Else Add a new entry for the source of the request to
   Request_Counter table;
End else
If (source_ID of the request in the suspicious list) Then
  limit = limit/2;
End if
If (request counter > limit) Then
  Add source ID to the suspicious list;
  Drop request;
End if
Else Process request;
