3. Transparency
 Mobile IP mechanism must be invisible to higher level protocol
& applications.
 The applications must able serve effectively even in general
issues of the mobile networking like lower bandwidth &
interruption in services.
 The mobile end-system should continue to keep its IP address
& the IP address is to be managed transparently with no effect
of mobility on an on-going communication.

4. Compatibility
 Mobile IP should be compatible with the existing
Internet Protocols.
 Mobile IP should not introduce any new tech in
networking layers and must support all web browsers.
 Enhanced mobile system must still able to
communicate with stable end-point that has no mobile
IP feature.

5. Security
 Mobile IP may Poses Issues like Authenticating Mobile IP .
 The host must receive packets from the HA , who is the
responsible to check receiver's IP address is correct or not.
 If attacker has fake IP then there is no easy way to find it,
which leads to easily compromises the high level protocols
used by applications.
 Mobile IP should provide users with secure communications
over the Internet as much as possible.

6. Efficiency & Scalability
 Enhancing IP should not flood the network with
new messages & new mew mechanisms must not
compromises the efficiency.
 Mobile IP must also be expandable so much to
support billions of moving hosts and also various
devices like laptop , cell phones etc.,
