| Summary: | Recently, wireless devices have been used significantly due to
the continuous and enormous services that they provide. The
Mobility Support has been designed to achieve a permanent and
continuing access to the Internet while the wireless devices are
roaming and changing their points of attachment. One of the
major challenges that arise is how to achieve seamless mobility
and high network performance. The Internet Engineering Task
Force (IETF) has developed Mobile IP, which allows Mobile
node to be connected while it is moving as well as functioning in
foreign mobile network zone using its original IP address. IETF
also in order to manage mobility of an entire network as single
unit, they developed NEMO Basic Support Protocol (NEMO BS),
which allows Mobile Routers to move and change their point of
attachment. When a Mobile Router connected to other mobile
router on foreign mobile network, it makes a hierarchical
structure known as nested mobile network; nested mobile
network suffers from deferent problems due its complexity
structure. When the level of nesting becomes high, problems of
tunneling overhead are increased, which will produce high
message delay and affect network performance. Many proposed
schemes have been introduced to overcome nested network
mobility issues. However, novel efforts are required. This
research aim to present and evaluate a new scheme to support
nested network mobility especially in high level of nesting. The
evaluation of this proposed scheme is done using analytical
approach. The proposed scheme enhancement is benchmarked
with NEMO protocol and ROTIO approach witch it based on
IETF standers. The result obtained had shown that the proposed
scheme has better performance than the benchmark.
