Abstract--To facilitate mobile computing, mobility protocols
have been proposed and mobility management involves signaling
costs. Widespread use of IP-enabled mobile devices have resulted
in increase in number of mobile users in the network and the
signaling cost on underlying mobility entities have increased
significantly, which will result in performance degradation of the
mobility protocols. However, there has been no comprehensive
cost analysis of mobility protocol entities that considers all
possible costs for mobility management. In this paper, we have
developed analytical models to estimate total costs of mobility
