Signaling Cost Analysis of Mobility Protocols using City Section Mobility Model

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. I
