Mobile IP conditional binding update.
  Mobile IP protocols use a correspondent registration procedure between a Mobile Node (MN) and its Correspondent Nodes (CNs) to maintain a valid and up-to-date binding association between MN’s home address and its current care-ofaddress whenever a handover occurs. This procedure plays a key role in optimizing the routing path between the two parties by avoiding any kind of dog-leg routing across the home network or the previous visited network. However, such a procedure reveals its inefficiency in multicast communication as multicast sources do not need to know the identity of multicast receivers and to interfere with their mobility events. Without an additional intelligence on Mobile IP entities to assess the nature of the communication session established with a CN, such behavior introduces an extra processing and inefficient use of the network resources for both CN and MN. In an attempt to solve these problems, we propose a new adaptive solution to enhance Mobile IP protocols (Mobile IPv4, Mobile IPv6, and Moving Network). In this regard, we extend Mobile IP specifications with two new registration schemes: dynamic address update and non-dynamic address update in response to the multicasting nature of CN.
With these two new schemes, MN and their mobility agents will be able to sense their communications and distinguish between multicast and unicast sources and therefore block sending binding information to multicast sources. We evaluate our solution by quantifying analytically the gain of the binding update messages that could be avoided in different mobility management scenarios.
