D8 Integration and Experimentation

• D8 is an output of WP 4 This WP will integrate
  the HW/SW developed () Qualitative study of the
  social and anthropological consequences of the
  utilization of the system.
• T4 .1 Small Area Scale Integration Integrate
  part of the HW/SW developed (reduced networking
  and services capabilities), and install it in
  each node in a small and test this system in
  order to identify HW or simple networking
  problems and integration errors. Fix
  problems/errors found verifying that the system
  operates correctly. (input to D8 - month 22 (July
  2004) All
• T4 .2 Small Area Scale Validation and Analysis
  Validate the small scale MobileMAN from a
  technical (i.e., the technical constraints and
  limitations of the system), and social
  standpoint. The latter will be performed by
  measuring the acceptance -- from Virtual
  Communities (VCs) of users -- of the MobileMAN
  system when running some simple application(s).
  This will task will also monitor the social
  construction and human behaviour of the VCs.

D11 MobileMAN functionalities enhanced set

• D11 HUT is responsible for this deliverable
  (month 25)
• D11 is an output of WP 3
• T3.2 Implementation of Location Protocols
  Develop new location and discovery protocols
  based on the nearness metric. Implementation of
  it for the Linux operating system. (input to D6,
  D11, D14)
• Service discovery embeeded in the routing
  protocol instead of users location
• T3.3 Routing and forwarding Develop routing and
  forwarding protocols for the self-organised and
  co-operative communications of MobileMAN.
  Implementation of them for the Linux operating
  system, in co-operation with the task on security
  (T3.4). (input to D6, D11, D14)

D11 MobileMAN functionalities enhanced set

• T3.4 Security and Co-operation Model
  Implementation of the collaborative reputation
  mechanism (CORE) proposed to solve ad hoc node
  misbehaviour. Implementation of the CORE
  mechanism for the Linux operating system, in
  co-operation with the task dedicated to the
  definition and implementation of the routing
  algorithm adopted by MobileMAN (T3.3). (input to
  D11, D14)
• T3.5 P2P delivery mechanisms Implementation of
  the P2P mechanisms designed in Task T2.6. (input
  to D11, D14)
• T3.6 Risk reduction in the system development
  This task will be activated, if required, by the
  self assessment procedure to tackle the risks
  emerging during the implementation of the system
  solutions. The objective of this task is the
  identification of alternative solutions for
  implementing the system solutions when adopted
  approaches are too complex and risky. (input to
  D11, D12, D14

WP 3
Objectives The aim of this WP is to implement
the MobileMAN innovative components at networking
and service layer of the architecture as defined
by WP2. Description of work The innovative
elements of the networking architecture of
MobileMAN consist of the MAC, Routing and
Location components. At service level the main
components is the security one. The work to be
done regarding these components includes all the
phases of the HW/SW development lifecycle, from
requirements analysis to testing (verification
testing). T3.1 Bursty-responsive MAC Develop new
MAC protocol and hardware supporting bursty
communication. The hardware will be based,
wherever possible, on a off-the-shelf 802.11
chipset whit ad-hoc programmed firmware. (input
to D12) - SUPSI DIE T3.2 Implementation of
Location Protocols Develop new location and
discovery protocols based on the nearness metric.
Implementation of it for the Linux operating
system. (input to D6, D11, D14) - CNR HUT

T3.3 Routing and forwarding Develop routing and
forwarding protocols for the self-organised and
co-operative communications of MobileMAN.
Implementation of them for the Linux operating
system, in co-operation with the task on security
(T3.4). (input to D6, D11, D14) HUT CNR T3.4
Security and Co-operation Model Implementation

WP 4
Description of work Given the high challenges of
this WP, the main tasks to be performed in it
(integration and acceptance) will be addressed at
two different area scales campus-wide area scale
(T4 .2 and T4 .3) and large area scale (T4 .4 and
T4 .5). T4 .1 Small Area Scale Integration
Integrate part of the HW/SW developed (reduced
networking and services capabilities), and
install it in each node in a small and test this
system in order to identify HW or simple
networking problems and integration errors. Fix
problems/errors found verifying that the system
operates correctly. (input to D8 - month 22)
All T4 .2 Small Area Scale Validation and
Analysis Validate the small scale MobileMAN from
a technical (i.e., the technical constraints and
limitations of the system), and social
standpoint. The latter will be performed by
measuring the acceptance -- from Virtual
Communities (VCs) of users -- of the MobileMAN
system when running some simple application(s).
This will task will also monitor the social
construction and human behaviour of the VCs.
(input to D8 - month 22), (D17 - month 34 )
All T4.3 Evaluation of MobileMAN Networking
Simulative study of the integration of MobileMAN
Networking components with other relevant

mechanisms to optimise the utilization of the
resources. (input to D16 - month 34) HUT, CNR,

II Year Activities

• The objectives reported below are the detailed
  criteria for evaluating the success of the second
  year of the project.
• MobileMAN architecture implementation (CNR)
• - Implementation and validation of the MobileMAN
  architecture as defined during the first year
  (see D5) considering both the original and the
  new reference model.
• New applications and services (Netikos)
• Adaptation of existing applications (or classes
  of applications) identified, during the first
  year, as ones that can become a customer
  advantage, when run on top of MobileMAN, compared
  to traditional technologies.
• Middleware (Cambridge)
• - Adaptation of Pastry middleware for the
  MobileMAN environment to exploit cross layering.
• - Development of new solutions for P2P
  information delivery based on Pastry.
• Co-operation Model (Eurecom)
• - Implementation and validation of the
  cooperation models and mechanisms defined during
  the first year.

26
II Year Activities (cont.)
Networking services (CNR, HUT) - Include the
cross-layering view at network/transport
layer - Design of packet forwarding schemes
suitable for MobileMAN. - Implementation and
validation of location scheme defined during the
first year. - Development and testing of a
complete ad hoc network Wireless Technologies
(SUPSI - DIE) - Include the cross-layering view
at datalink layer. - Design and implement a full
datalink layer that includes the enhanced MAC
protocol for ad hoc networks as designed during
the first year. Socio-economic Model (SUPSI -
DLS) - Apply the developed methodology for
evaluating social, anthropological, and economic
potential of MobileMAN, and provide the results
for improving the technical parts.
27
II Year Success Criteria
The goals for evaluating the success of the
second year of the project are - The software
implementation of the solutions defined and
studied during the first year, except the
MobileMAN enhanced NIC. - The integration of the
developed solutions in a fully functioning
testbed. - Preliminary measures of the users
satisfaction of the ad hoc networking paradigm.
These measures will be mainly done by empirical
research based on forms to be filled. In
addition, some measurements with a small group of
users (on a simplified testbed) will be also
performed. - To investigate market-based
mechanisms for exploiting the self-organised
paradigm. This will take into account both the
users satisfaction and the advantages provided
by the MobileMAN environment to some class of
applications.
