Abstract
To support IP-mobility of networks in motion, IETF
proposed Network Mobility (NEMO) protocol that uses
various signaling messages to ensure connectivity of
the mobile nodes with the Internet. However, there has
been no comprehensive cost analysis of mobility protocol
entities that considers all possible costs. In this paper, we
have developed analytical models to estimate total costs
of key mobility management entities of NEMO. We have
presented numerical results to demonstrate the impact of
network size, mobility rate, traffic rate and data volume
on these costs. Our cost analysis will thus help network
engineers in estimating actual resource requirements for
the key entities of the network in future design.
