The validity of the mobility model used to evaluate a cellular network determines the validity of the evaluation. In the literature, unrealistic assumptions on mobility are exercised for the sake of simplicity. In this paper, we present a novel mobility model which is realistic in the sense that it captures the moving-in-groups, conscious traveling, and inertial behaviors of the subscribers whi...

Mobile ad hoc network is an autonomous system of mobile nodes connected by wireless links without any infrastructure support. Mobility of nodes in MANET is defined as entity based or group based. Entity mobility is designed to simulate the movement of each individual. Group mobility model are designed to simulate the movement of nodes in a group. Many of the application of mobile ad hoc network...

In this paper we present a mobility model for simulations of wireless access scenarios. This new model has been developed to reduce the shortcomings of previous models in capturing higher-order statistical dependencies in user behavior. The proposed model strikes a balance between the abstraction level of some purely stochastic path generation models that lack certain important properties of th...

In this paper we study the so-called random waypoint (RWP) mobility model in the context of cellular networks. In the RWP model the nodes, i.e. mobile users, move along a zigzag path consisting of straight legs from one waypoint to the next. Each waypoint is assumed to be drawn from the uniform distribution over the given convex domain. In this paper we characterise the key performance measures...

In this paper is described a model of residential mobility, built to simulate individual households, their perception of and reaction to varying conditions across different scales of interaction, and their movements to occupy housing in a physical, social, and economic environment. The methodology underpinning the model is based on an automata core, which leverages the advantages it offers in t...

Modeling arbitrary connectivity changes of mobile ad hoc networks (MANETs) makes application of automated formal verification challenging. We introduced constrained labeled transition systems (CLTSs) as a semantic model to represent mobility. To model check MANET protocol with respect to the underlying topology and connectivity changes, we here introduce a branching-time temporal logic interpre...

In order to conduct meaningful performance analysis of routing algorithms in the context of Mobile Ad Hoc Networks (MANET), it is essential that the underlying mobility model on which the simulation is based reflects realistic mobility behavior. However, current mobility models for MANET simulation are either unrealistic or are tailor-made for particular scenarios. Furthermore, none of the exis...

Vehicular ad-hoc networks are a prospective technology which contribute to safer and more efficient roads. Inter-vehicle communication provides drivers and concerned authorities with information about road conditions, supports the coordination in case of emergency and improves traffic management. Furthermore, vehicular ad-hoc networks offer information and entertainment services to mobile users...

Systems Optimization for Mobility Management Ashutosh Dutta Wireless network mobility frees the user from location dependence but requires additional mechanism to preserve network connectivity. Mobility events occur when user movement causes one network connection to be replaced by another. A network connection has associated with it properties, for example, network attachment points, network i...
