Abstract
To fulfil the need for an uninterrupted Internet access along with the move in
mobile networks as an alternative to the end-host mobility, the IETF NEMO working
group was created to extend basic end-host mobility support in Mobile IPv6 (MIPv6).
This group standardizes NEMO Basic Support Protocol (NEMO BS) to support
network mobility. However, the handover latency in NEMO BS is high and the nested
tunnels’ problem in the nested NEMO networks is not considered in the main
specification of this protocol. Issues affecting the provision of QoS guarantees during
the handoff process in NEMO BS are the handover latency, the disruption time, and
the handoff failure and the packet loss. Many schemes have been proposed to solve
these issues by optimizing the handover signalling procedure and by proposing routing
optimization scheme for NEMO. This research proposes a new framework that
combines a better optimized signalling handover procedure, and a proposed Routing
Optimization scheme as a solution for the lack of the nested tunnels’ problem.
Mathematical results highlight the importance of the proposed schemes compared to
the related recent schemes are provided, revealing that the proposed scheme has
reduced the handover latency and the service disruption time. Simulated experiments
using OMNeTt++ 4.3.1 simulation tools have been carried out to evaluate the proposed
framework. The results of the experiments showed that the handover latency, the
disruption time, and the packets lost in the proposed framework has been reduced by
24.34%, 91.88% and 99.28% respectively compared to NEMO BS.
