| Summary: | To achieve the requirement of the improvement applications and guarantee the Internet
access for mobile hosts and networks, the Internet Engineering Task Force (IETF)
proposed Mobile Ad Hoc NEMO (MANEMO) architecture. However, the integration of
NEMO and MANET introduces many challenges such as the redundant tunnel problem
and Exit Router selection when multiple Exit Routers to the Internet exist. This paper aims
to propose a scheme that discovers and selects the gateway which improves the
performance and the robustness of the network regardless of routing protocol used. This
is done by extending the Tree Discovery Protocol (TDP) used by NEMO BSP and the
Neighborhood Discovery protocol used by MANET and the gateway selection is based on
multiple criteria: the hop count, the nested level, the stable time and the number of nodes
registered at the intermediate nodes. The OPNET Modeler 14.5 is used to evaluate the
proposed scheme and compare its performance with the standard NEMO BSP and the
Multi-homed MANEMO (M-MANEMO) approach. The results show that the average data
packets dropped of the proposed scheme is 28.6% less compared to the NEMO BSP and
63% compared to the M-MANEMO. And in a larger scale MANEMO with high traffic
load and fast mobility, the proposed scheme outperforms the M-MANEMO with reduced
end-to-end delay around 21.6%. Whereas NEMO BSP has 68.7% more end-to-end delay
in compare. These delays cause that the proposed scheme has 66.6% less voice jitter
compared to M-MANEMO. |
