| Summary: | Mobile networking environments have been developing very rapidly in line with the
increase demand of users. Multicast is defined as the delivery of data to a set of selected receivers.
When a mobile node (MN) moves to a new subnet it needs to continue certain services that have
already been established at the previous subnet. It is a difficult problem to maintain simplicity and
reachability of a MN when moving (handover) from one network to another. Context transfer (CXTP)
gives support of the seamless handover based on service continuation using context. It aims to
contribute to the enhancement in handover performance and proposed for MN for quickly reestablishment
of their services when the nodes move and change their access routers. This paper
focuses on evaluating the performance of predictive method employed by CXTP to enhance the
handover performance in hierarchical mobile multicast environment namely M-HMIPv6. Our research
aims to improve the performance of the mobile node during handover in a multicast session; this is
done by reducing the mobile node’s service recovery time and signaling cost. The evaluation is carried
using mathematical analysis. The performance metrics used are service recovery time, and signaling
cost |
