| Summary: | Network mobility basic support (NEMO BS) protocol is an entire network, roaming
as a unit which changes its point of attachment to the Internet and consequently its reachability
in the network topology. NEMO BS doesn’t provide QoS guarantees to its users same as
traditional Internet IP and Mobile IPv6 as well. Typically, all the users will have same level of
services without considering about their application requirements. This poses a problem to
real-time applications that required QoS guarantees. To gain more effective control of the
network, incorporated QoS is needed. Within QoS-enabled network the traffic flow can be
distributed to various priorities. Also, the network bandwidth and resources can be allocated to
different applications and users. Internet Engineering Task Force (IETF) working group has
proposed several QoS solutions for static network such as IntServ, DiffServ and MPLS. These
QoS solutions are designed in the context of a static environment (i.e. fixed hosts and
networks). However, they are not fully adapted to mobile environments. They essentially
demands to be extended and adjusted to meet up various challenges involved in mobile
environments. With existing QoS mechanisms many proposals have been developed to provide
QoS for individual mobile nodes (i.e. host mobility). In contrary, research based on the
movement of the whole mobile network in IPv6 is still undertaking by the IETF working
groups (i.e. network mobility). Few researches have been done in the area of providing QoS for
roaming networks. Therefore, this paper aims to review and investigate (previous /and current)
related works that have been developed to provide QoS in mobile network. Consequently, a
new proposed scheme will be introduced to enhance QoS within NEMO environment,
achieving by which seamless mobility to users of mobile network node (MNN). |
