| Summary: | Quality of Service (QoS) is defined as the
capability of network elements (e.g. application, host and
router) to provide some sort of assurance and service
differentiation for consistent network data delivery.
Recently, Internet Engineering Task Force (IETF) has
introduced Network Mobility Basic Support (NEMO BS)
protocol (RFC 3963) to address the challenges of the entire
network mobility (such as the movements of trains, buses,
ships and aircrafts). However, NEMO BS is designed
without QoS support in mind. Similar to MIPv6, it can
hardly offer same level of services (i.e. Best-Effort) to all the
users without obligation to the applications needs. This poses
a problem to real-time applications that required certain
level of QoS commitment. Moreover, delays in data delivery,
packet loss and higher signaling overheads are likely to
transpire because of suboptimal routing and multiple
encapsulations of data packets. Incorporating QoS with
mobility support seems to be needed to fulfill the necessity of
users in mobile network. This paper proposes a new scheme
that deploys Differentiated Service (DiffServ) QoS-based
model to achieve smooth delivery of real-time traffic in
heterogeneous mobile networks. Furthermore, the proposed
scheme uses the mechanisms of Fast Hierarchical Mobile
IPv6 (FHMIPv6) to reduce location update signaling issues,
since the MR doesn’t concern about local and global
movement. It also conquers the weakness of NEMO
inefficient routing by utilizing the methodology of MIPv6
route optimization to bypass the HA and catering optimal
path. The feasibility of the proposed scheme is evaluated
using Network Simulator (NS-2). The performance of
proposed scheme is benchmarked with the standard NEMO
basic support protocol. Eventually, the obtained results
reflect that the proposed scheme outperforms the standard
NEMO BS protocol by diminishing the handover latency. |
