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. (input to D8 - month 22), (D17 - month 34 ) All


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)

II Year WPs and Tasks


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

WP 3


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 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) Eurecom

T3.5 P2P delivery mechanisms: Implementation of the P2P mechanisms designed in Task T2.6. (input to D11, D14) Cambridge

WP 3 (cont.)


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 elements as the connection to Internet, as well as congestion control and error recovery mechanisms to optimise the utilization of the resources. (input to D16 - month 34) HUT, CNR, Eurecom

WP 4


• 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.

II Year Activities


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.

II Year Activities (cont.)


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.
