2. Outline
 Motivation – Opportunistic networks
 SAPERE project
 Music Festival
 Description
 Requirements
 What are we expecting from you?
 What should you think about?
2

3. Motivation
 Traffic control
 Alerts about accidents or dangers on
the road (e.g. ice, or oil)
 Cars navigators using context
information. (e.g avg. speed of cars)
 Virtual tourist guide
 Avoid very crowded streets
 Receive information about event
that are happening close to you
 Cinema, theather, etc..
 Taxi booking service
3

4. Motivation
 Characterized by:
 Large Scale
 Openness
 Unpredictability
 Requirements:
 Scalability
 Robustness
 Adaptability
 Context-aware

5. SAPERE project
 Theoretical and practical framework for
decentralized development and execution of
self-aware and adaptive services for future and
emerging pervasive network scenarios.
 Chemical Interactions among Services
 Smooth data/service distinction
 Spontaneous interactions of
available services
 Bio-chemical reactions
 Middleware for Android phones / tablets
 Context-awareness (user, situation recognition)
 Case Study
 Focus on public/private displays for crowd steering
 Domains
 Context-Aware Advertisement, Crowd Steering, User guidance
 EU Funded Project (SAPERE: http://www.sapere-project.eu)
FACULTÉ DES SCIENCES U Bologna, U Modena, U Linz, U St-Andrews
 Collaboration: U Geneva,
ÉCONOMIQUES ET SOCIALES
 2010-2013

6. Music Festival
 Features:
 Current centralised solutions are not
scalable:
 It’s not possible to make calls, send
messages, or have internet connection.
 Mobile network overload.
 High density of people, most of them
bringing mobile phones or pdas.
 Open spaces:
 It makes easy the positioning (use of GPS)
6

7. App. Requirements
 Crowd steering:
 A user wants to find other users.
 A user wants to find a point of interest.
 Organisers want to publish events (without using
centralised infrastructure):
 Taxi or bus location
 Music Festival Agenda
 Emergency exits, toilets, bars, merchandising.
 A bar owner wants to advert offers during the festival
7

8. App. Requirements
 Social Network:
 Add people to your social network
 Sharing profiles, pictures
 To know if people in your social network are in the music festival
 A user wants to chat with other users (friends)
 One to one, or one to n-users.

9. What are we
expecting from you?
 Designing the application:
 Use of self-organising design patterns.
 Contribution of each pattern.
 Relationships between them.
 Description of the entities participating in the system.
 Description of the interactions between the entities.
9

10. What you should
think about?
 How does the information spread?
 Analysis of the different spreading algorithms existing in the
literature (e.g. probabilistic, position-based, counter-based)
 Routing algorithms for opportunistic networks?
 Are they required? When should they be used?
 What are the current technologies that give support for this
type of infrastructures?
 Bluetooth, zigbee, wi-fi, direct wi-fi…etc.
 Are they satisfying the current requirements of this type of
applications?
 Which one would be the best?
10

11. What you should
think about?
 What are the main challenges in the implementation?
 Information collisions, network overload, Memory, CPU
 How could these problems be overcome?
 How can we simulate the application?
 What is the goal of the simulation? Scalability, robustness,
Feasibility? Validating the design?
 Which are the existing tools that allow us to simulate this
application. (Repast, one, ns2, …)
 SASO workshops. Deadline: 4th July
