Statistical Equivalent Models, or SEMs, have recently been proposed as a general approach to study computer simulators. By fitting a statistical model to the simulator’s output, SEMs provide an efficient way to quickly explore the simulator’s result. In this paper, we develop a SEM for random waypoint mobility, one of the most widely used mobility models employed by network simulators in the ev...

In this dissertation, I generalize the relocation analysis of MAC algorithms for Mobile Ad-hoc Network by creating different mobility models. The models of Constrainedjump mobility, Parallel-motion and Flock mobility were implemented in TOSSIM. The Constrained-jump model is used for simulating two versions of a MAC Algorithm [3, 9] and comparing their performance. Two functions are derived from...

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 i...

User mobility is of critical importance when designing mobile networks. In particular, ‘‘waypoint’’ mobility has been widely used as a simple way to describe how humans move. This paper introduces the first modeling framework to model waypoint-based mobility. The proposed framework is simple, yet general enough to model any waypoint-based mobility regimes. It employs first order ordinary differ...

Ad hoc network consists of a set of identical nodes that move freely and independently and communicate among themselves via wireless links. The most interesting feature of this network is that they do not require any existing infrastructure of central administration and hence is very suitable for temporary communication links in an emergency situation. This flexibility, however, is achieved at ...

To bring VANET into reality, it is crucial to devise routing protocols that can exploit the inherited characteristics of VANET environment to enhance the performance of the running applications. Previous studies have shown that a certain routing protocol behaves differently under different presumed mobility patterns. Bypass-AODV is a new optimization of the AODV routing protocol for mobile ad-h...

Existing group mobility models were not designed to meet the requirements typical of current and future short distance wireless networks scenarios, that need, in particular, accurate, up-to-date information on the position of each node in the network, combined with a simple and flexible approach to mobility modeling. A new model for group mobility in wireless networks, named MoMo, is proposed i...
