| Summary: | The performance of Network Mobility (NEMO) used to manage network mobility does
not provide satisfactory result in terms of delay, throughput and session continuity when
dealing with multihomed mobile network. Enhanced Mobility Solution in Mobile IPv6
Network is extremely complex; the study addressed the multihoming issues of MIPV6
Networks on the basis of NEMO Basic Support, analyzes the benefits of multihoming
and discusses implementation issues of all classes of multihoming possibilities.
Additionally, Policy-based routing, as one of the multihoming benefits, is studied in
particular.
A framework based on policy based routing protocol was proposed for handling both the
inbound and the outbound traffic on a mobile network, under specified policies which
consider packet characteristics, current network situation and user preferences. The
interface selection algorithm was based on NEMO implementation structure using a
technique of mutihoming which was extended to MIPv6 concepts The outcome of this research work are: a designed policy protocol for policy messages
communication between the Mobile Router and the Home Agent, the framework is
simulated using Network Simulator (NS2) with an extension of mobiwan, the result
shows the end to end delay, average end to end delay, overhead, optimal routing path,
average inter-packet latency and throughput of the developed system. The information
from the analysis of the result shows that the enhanced solution has drastically reduced
average packet delay to minimum with 72.5 %( 0.040s to 0.011s), and end-end delay with
75 %( 0.020s to 0.005s) compared with NEMO solution. Overhead in the mobile network
was maintained by 10bytes per nested level by keeping the session.
The solution is important by enterprises in making decision to acquire internet
connectivity for the purpose of connectivity redundancy and traffic load distribution
optimization. This result is very important for time sensitive application that requires
stable network condition. |
