  Network mobility basic support (NEMO BS) protocol (RFC 3963) is an extension
of Mobile IPv6. The NEMO BS embraced by the IETF working group to permit any
node in the portable network to be accessible to the Internet despite the fact
the network itself is roaming. This protocol likewise Mobile IPv6 does not
deliver any kind of Quality of Service (QoS) guarantees to its clients. It can
barely offer the same level of services (i.e. Best-Effort) to all the users
without obligation to the needs of applications. These propositions a challenge
to real-time applications that demand a precise level of QoS pledge. The
Differentiated Services have recently come to be the most widely used QoS
support technology in IP networks due to its relative simplicity and
scalability benefits. This paper proposes a new scheme to provide QoS to mobile
network nodes within the NEMO context. The proposed scheme intends to reduce
handover latency for the users of MNN as well as alleviates packet losses. The
feasibility of the proposed enhancement is assessed by measuring its
performance against the native NEMO BS standard protocol using the NS-2
simulator. The obtained results in the simulation study have demonstrated that
the proposed scheme outperforms the standard NEMO BS protocol.
