In the performance evaluation of a protocol for an ad hoc network, the protocol should be tested under realistic conditions including, but not limited to, a sensible transmission range, limited buffer space for the storage of messages, representative data traffic models, and realistic movements of the mobile users (i.e., a mobility model). This paper is a survey of mobility models that are used...

Simulations play a vital role in implementing, testing and validating proposed algorithms and protocols in VANET. Mobility model, defined as the movement pattern of vehicles, is one of the main factors that contribute towards the efficient implementation of VANET algorithms and protocols. Using near reality mobility models ensure that accurate results are obtained from simulations. Mobility mod...

While it is crucial to test and evaluate protocol implementations in a real world environment, simulations are still commonly used as a first step in the protocol development for VANET research. One of the most important parameters in simulating ad-hoc networks is the node mobility. It is important to use a realistic mobility model so that results from the simulation correctly reflect the real-...

When analyzing dissemination protocols in mobile ad-hoc networks the underlying mobility model is an important factor because it strongly influences the performance of these protocols. So far most of the research only dealt with homogeneous mobility models like the very common Random Waypoint Mobility Model and the Random Walk Mobility Model. In this paper we introduce a new model, the Area Gra...

In this paper, we present a novel mobility model which is realistic in the sense that it captures the moving-ingroups, conscious traveling and inertial behaviors of the subscribers while respecting the non-pass-through feature of some structures like households, and preserving the autonomy of the subscribers. The mobility and call patterns of the subscribers are determined according to the locu...

Mobile Ad Hoc networks are subject to some unique security issues that could delay their diffusion. Several solutions have already been proposed to enforce specific security properties. However, mobility pattern nodes obey to can, on one hand, severely affect the quality of the security solutions that have been tested over ”synthesized” mobility pattern. On the other hand, specific mobility pat...

We describe a modeling framework to study the spread of malware over realistic wireless networks. We develop (i) methods for generating synthetic, yet realistic wireless networks using activity-based models of urban population mobility, and (ii) an interaction-based simulation framework to study the dynamics of worm propagation over wireless networks. We use the prototype framework to study how...

One of the most important components of mobile ad-hoc network simulations is the mobility model, since it defines the movement of mobile nodes and thus indirectly the network topology. The network topology at a given time in turn influences the performance of an adhoc network, for example the performance of routing algorithms changes with the mobility model. In this paper we introduce a communi...
