Social Network
Founded Mobility Models for Ad Hoc Network Research
Abstract
Almost
all work on mobile ad hoc networks relies on simulations, which, in
turn, rely on realistic movement models for their credibility. Since
there is a total absence of realistic data in the public domain,
synthetic models for movement pattern generation must be used. However,
the most widely popular models currently used in mobile ad hoc networks
research are too simplicistic (i.e., random way point). We note that
the movement is strongly affected by social relationships. Fortunately,
humans are known to associate in particular ways that can be
mathematically modelled. Thus, we propose a new class of mobility
models founded on social network theory, since this has empirically
been shown to be useful as a means of describing human relationships.
The
main result of our investigation is the design of the Community based
Mobility Model, a model based on the analysis of community structure in
social networks that will be presented at REALMAN'06. This model has
been validated using real traces provided by the Haggle Project.
The
aim of this project is to provide simulation tool for the mobile
networking community, and in particular in the areas of ad hoc
networking, delay tolerant and opportunistic networking. In fact, the
tool may be very useful to simulate scenarios characterised by
disconnections and where patterns of colocation are exploited to
improve the performance of the protocols and systems (see some DTN
protocols).
Community based Mobility Model
This
tool generates movement traces for the ns-2 simulator based on the
Community based Mobility Model (CMM) described in this paper. The tool
is written in C++ and is based on standard C++ libraries. The tool also
generates XML traces (according to the ANSim XML Schema) that can be
easily translated to the formats used in Glomosim, etc, for example
using XSLT.
This model has been validated using real traces provided by the Haggle
Project at Intel Labs Cambridge.
