“…Thus, routing is very important in mobile adhoc networks where mobility models must be evaluated with respect to end to end delay and efficient data transmission. Mobility models are intended to focus on individual movement patterns due to point to point communication in cellular networks [11][12] [4-5] whereas ad-hoc networks are designed for group communication. Such models [12][13] are suggested to maintain movement, and efficient transmission among nodes in real life applications.…”

In addition to this, these models are mainly focused on the individual motion behavior between mobility eras with minimum simulation time in which a mobile node moves with constant speed and direction.…”

“…Traces are those mobility patterns that are observed in real life systems. Traces provide accurate information, especially when they involve a large number of participants and an appropriately long observation period [10][11][12][13][14][15][16][17][18]. However, new network environments (e.g.…”

Abstract-A Wireless Ad hoc Network is a collection of wireless nodes forming a self-configuring network lacking of using any obtainable transportation. Since Wireless Ad Hoc Networks are not currently deployed on a large scale, research in this area is generally simulation based. Among other simulation parameters, the mobility model plays a significant role in determining the protocol performance with the help of mobility models in Wireless Ad Hoc Network. Thus, it is essential to study and analyze various mobility models and their effect on Wireless Ad Hoc Network protocols. In this document, we survey and examine different mobility models proposed in the recent research literature.

“…Among the engineering tasks, planning and optimization of TAs (or LAs and RAs for previous generations of cellular networks) considering signaling overhead have been dealt with extensively. For models and algorithms of TA layout optimization and re-configuration, we refer to [6,7,9,15,27,28] and the references therein. Another line of research is the design of unconventional location update and paging schemes, such as mobility-model based TAU and sequential paging, see, for example, [4,21,22,29].…”

Avoiding signaling congestion is a key aspect in location management of cellular networks. The signaling load in this context corresponds to the use of location update and paging messages for tacking user equipments (UEs).Signaling congestion may occur due to many UEs behaving in a similar manner, e.g., massive and simultaneous UE mobility in a train movement scenario. For Long Term Evolution (LTE) networks, location management can be based on the use of tracking area lists (TALs), each being a list containing multiple tracking areas (TAs). In this paper, the scheme of using TALs with overlapping TAs is applied for signaling congestion mitigation. One or multiple TALs that potentially overlap are allocated to each cell, and the TALs are assigned to the UEs that make their location updates in the cell. We derive linear programming formulations for finding the optimal proportional use of overlapping TALs for congestion avoidance. The main advantage of our approach is that it does not require the collection of detailed UE mobility information apart from what is available to the network. We report numerical results for realistic scenarios. The optimization approach yields * Corresponding author. Preprint submitted to Computer Communications JournalAugust 6, 2012promising results for reducing signaling congestion, and the performance region of optimized overlapping TALs goes significantly beyond the capability of the conventional TA scheme.

In mobile adhoc network, nodes of position change due to dynamic nature. There should be a provision to monitor behavior and position of the on the regular basis. In this paper, importance of management schemes in adhoc networks is studied. Further, mobility models and reviewed and classified by incorporating real life applications into an account. Mobility and Traffic pattern of mobility models are generated by using AnSim Simulator.
