User-Centric Mobility Models for Opportunistic Networking

  title={User-Centric Mobility Models for Opportunistic Networking},
  author={Chiara Liliana Boldrini and Marco Conti and Andrea Passarella},
In this chapter we survey the most recent proposals for modelling user mobility in mobile pervasive networks, and specifically in opportunistic networks. We identify two main families of models that have been proposed. The first modelling approach is based on the observation that people tend to visit specific places in the physical space, which therefore exert special attraction on them. The mechanics of user movements are defined based on these attractions. The second approach is based on the… 
Exploring personal interest in intermittently connected wireless mobile social networks
The performance of these schemes with an interest-driven mobility model is evaluated and it is proposed to take the user interest into account when determining routing strategies to further improve the performance ofThese schemes for mobile social networks.
Synthetic map-based mobility traces for the performance evaluation in opportunistic networks
This paper shows a quite simple way to integrate location-based services into a scenario modeling tool and evaluates the performance of it, as well as showing that the runtime for the scenario generation is pretty small, even though location- based services are used.
Periodic patterns in human mobility
The novel concept of a periodic encounter community is introduced, a collection of individuals that share the same periodic encounter pattern, which is of particular relevance to human-based opportunistic communication networks.
Properties and Impact of Vicinity in Mobile Opportunistic Networks. (Propriétés et impact du voisinage dans les réseaux mobiles opportunistes)
A formal definition of vicinities in DTNs is proposed and the new resulting contact/intercontact temporal characterization is studied and a Vicinity Motion-based heuristic for pairwise shortest distance forecasting is exposed.
Models for information propagation in opportunistic networks
The topic of this thesis is Opportunistic Networks (OPNETS), a type of mobile ad hoc network in which data are propagated by the movement of the network devices and by short-range wireless
A Data Dissemination Algorithm for Opportunistic Networks
This paper proposes a socially-based data dissemination technique for opportunistic networks called Social Dissemination, which assumes that nodes are grouped into communities, where nodes in the same community meet often, while at the same time certain nodes may have relationships with nodes from other communities.
Social Relationship Enhanced Predicable Routing in Opportunistic Network
This paper proposes social relationship enhanced predicable routing (SREP) in the opportunistic network and introduces Page Rank algorithm to quantify social degree of node and shows that SREP is an effective routing protocol in a specific scenario based on the human motion.

The results show that local user’s social interactions and collaborations help to improve the overall message delivery performance in the network, and that a higher communication range improves the overallmessage delivery performance but when communicating in a shorter range, users’ interactions and collaboration are significant for data forwarding.
Context awareness in opportunistic computing
This thesis proposes a protocol that is a context aware integration of traditional end-to-end and opportunistic routing and has the capability of dynamically switching between both the routing modes depending upon the network situation.
Feasibility Study Opportunities in Opportunistic Computing
Technological advances are leading to a world replete with mobile and static sensors, user cell phones, and vehicles equipped with a variety of sensing and computing devices, thus paving the way for a multitude of opportunities for pairwise device contacts.


Users Mobility Models for Opportunistic Networks : the Role of Physical Locations
It is argued that, while being a fundamental building block, social relationships alone cannot be the only driver for the mobility process and the Home-cell Community-based Mobility Model (HCMM) is proposed, which retains the social-aware features of CMM and permits to easily control the relationships between users and their preferred physical locations.
An Obstacle Based Realistic Ad-Hoc Mobility Model for Social Networks
This paper captures the preferences in choosing destinations of pedestrian mobility pattern on the basis of Social Factor (Y F) and tries to find out the essential impact of Y F on the Pause Time of the nodes and presents a more realistic mobility distribution pattern.
Designing mobility models based on social network theory
A new mobility model founded on social network theory is proposed that allows collections of hosts to be grouped together in a way that is based on social relationships among the individuals, and is validated with real traces by showing that the synthetic mobility traces are a very good approximation of human movement patterns.
Modeling Time-Variant User Mobility in Wireless Mobile Networks
A novel time-variant community mobility model is proposed that defines communities that are visited often by the nodes to capture skewed location visiting preferences, and use time periods with different mobility parameters to create periodical re-appearance of nodes at the same location.
A survey of mobility models for ad hoc network research
A survey of mobility models that are used in the simulations of ad hoc networks and illustrates how the performance results of an ad hoc network protocol drastically change as a result of changing the mobility model simulated.
Modeling the sociological aspects of mobility in ad hoc networks
A social mobility model is proposed that takes an arbitrarily shaped model of a social network and turns it into a simulation that reflects the relationships between users and their probability to interact.
On profiling mobility and predicting locations of wireless users
This analysis of wireless network users' mobility trace data not only validate the existence of the so-called sociological orbits, but also demonstrates the advantages of exploiting it in performing hub-level location predictions.
On Natural Mobility Models
The need for a better characterization of natural mobility is discussed, and a novel mobility modelling approach that focuses on the behavioral aspect of individuals and the interactions between them is devised, which fulfils a gap between individual and group mobility models.

A method to estimate the physical location of users from a large trace of mobile devices associating with access points in a wireless network is presented and it is discovered that the speed and pause time each follow a log-normal distribution and that the direction of movements closely reflects thedirection of roads and walkways.
Impact of Social Mobility on Routing Protocols for Opportunistic Networks
This paper takes into consideration group mobility models, whose movement patterns have shown to be remarkably similar to real-world user movements, and considers routing protocols representative of a broad range of schemes.
