Abstract--Increasing demand for mobility in wireless data
network has given rise to various mobility management schemes.
Most of the analysis on mobility protocols used Random Way-
point (RWP) mobility model which fails to represent realistic
movement pattern. In this paper, we have used City Section
Mobility (CSM) model, a realistic mobility model, to compare
the signaling costs of two host-mobility protocols: HIMPv6 and
SIGMA, and two network-mobility protocols: NEMO BSP and
SINEMO. Our analysis shows that the signaling cost of SIGMA
(SINEMO) is much less than that of HMIPv6 (NEMO BSP)
for both mobility models. We further find that the lookup cost
component, which is independent of mobility models, dominates
the total signaling cost. Hence, the total signaling costs of mobility
protocols do not vary much for different mobility models.
