“…The phenomena shown by our results are consistent with those in wireless cellular networks presented in [15], where the authors analyzed the impact of the CMR (Call-toMobility Ratio) on the performance of different individual location update and paging schemes, namely MS (Movementbased), DS (Distance-based), and LS (Location-based). In [15], when the CMR is large, the difference as the cost gain in percentage of total cost among DS, MS and LS becomes negligible.…”

This paper proposes two Individual paging schemes, then presents a comparative analysis on the signaling cost functions of Mobile IP (MIP) with different paging protocols and paging schemes and investigates constructing optimal paging areas using discrete system model as a mobility model. In wireless mobile Internet, mobile hosts often visit foreign networks that might be far away from their home networks and the occurrences of their inter-domain movement are relatively rare. In this scenario, our analytical results show that paging, particularly individual paging, can significantly improve the total signaling cost of MIP. We show that Domain paging can bring about considerable cost saving compared to FA (Foreign Agent) paging. Our results also demonstrate the significant advantages of Individual Paging over Static Aggregate Paging. The results show that specifying the optimal paging area size is critical in saving signaling cost of MIP with paging support.

“…In order to analyze the signaling burden related to a Location Management algorithm, a relationship between the call and mobility models of the user can be useful, as shown in [22][23][24][25][26][27][28][29], where the call-to-mobility ratio is utilized. For the analysis that follows, we assume that the user moves randomly and that all the location areas under study have the same area, even if this size might not be optimum (dynamic location area size strategies are proposed in [30][31][32][33][34][35]).…”

“…Thus, according to the transition probabilities derived in the preceding section, E u ðmÞ can be evaluated as [10,14] For the proposed distance-based scheme, the number of updates does not depend only on the number of movements, but also on the direction of movement; specifically, the probability of having the mobile roam toward the next ring-cell. For each update to occur, a minimum of D movements (or cell boundary crossings), or a maximum of m movements would be required depending on how many transitions were actually made to the neighbouring cells.…”

“…For the computation of paging cost, the same analysis framework [14] as for an ordinary distance-based scheme is found applicable. Generally, given a per unit paging cost of V ; the calculation comprises two parts}to estimate the probability of having the roaming mobile reside in subarea j (i.e.…”

SUMMARYIn this paper, a new tracking strategy, the directivity-aware location updating scheme was developed to better utilize the distinct characteristics of individual users on travelling directions. In this new adaptive scheme, an optimal distance-based update threshold is selected according to the call-to-mobility ratio and a transitional directivity index, introduced to give indications of the mobile's travelling patterns. It is found that as far as mobility characteristics are concerned, the actual transitional direction of roaming mobiles plays a significant role in selecting the optimal threshold in addition to the usual perception about mobility rate. Its advantage becomes even more visible when an optimal threshold is not theoretically obtainable due to certain restrictions imposed by the network during times of high system loadings. Simulation results show that the additional information made available about roaming mobile's transitional directivity is critical to ensure that the best available sub-optimal threshold is realizable. Other advances in this paper include the simplification of existing Markovian movement model. With the improved model presentation, the number of states necessary to simulate such memoryless movements is reduced. Consequently, the computational complexity involved is also lessened.
