| Summary: | Network Mobility (NEMO) basic support protocol (RFC
3963) has been proposed by Internet Engineering Task Force
(IETF) to extend the operation of Mobile IPv6 for providing
uninterrupted Internet connectivity to the communicating nodes of
mobile networks. The protocol operates by moving the mobility
functionality from Mobile IPv6 mobile nodes to a mobile network’s
router. This router device is known as a Mobile Router (MR) in the
mobile network, which performs binding update with its Home
Agent (HA) to establish a bi-directional tunnel between the HA and
MR. NEMO is designed with elucidation so that network mobility
is transparent to the nodes inside the Mobile Network in order to
reduce location update signaling that would occur by each a Mobile
Network Node (MNN). Nevertheless, delays in data delivery and
higher overheads are likely to transpire because of suboptimal
routing and multiple encapsulations of data packets. Therefore, this
paper proposes a new scheme using the mechanisms of Fast
Hierarchical Mobile IPv6 (FHMIPv6) to reduce location update
signaling issues. Furthermore, the proposed scheme introduces the
use of DiffServ model to achieve smooth delivery of real-time
traffic in heterogeneous mobile networks. Eventually, it aims to
minimize the packet loss and diminish the handover latency as well.
