«Supporting Dynamic Evolution of Hybrid Sensor Services»

Work programme

During the second year, the associated team will build on the preliminary results we obtained, namely the REMORA component model and the DIGIHOME service-oriented platform to introduce the self-adaptation principles. In particular, we plan to operate in two steps:

Applying Feedback Control Loops in Wireless Sensor Networks will address the challenge of developing self-adaptive WSN infrastructures for supporting the dynamic adaptation of sensors. This objectives therefore requires the definition of deployment and reconfiguration services at the sensor level, while the network level will have to be extended with further services dealing with the adaptation strategies to apply according to the evolutions observed in the physical and virtual environments. At this stage of the project, the DIGIHOME demonstrators will validate the capability of the REMORA components to evolve over time by discovering sensors and reconfiguring the associated sensor services.

Combining Feedback Control Loops in Multi-scale Environments will extend the above challenge with the support of hybrid adaptation policies impacting not only traditional service-oriented architectures, but also WSN. This includes the definition of a versatile adaptation model for applying distributed adaptations at various scales of the systems, from application servers down to sensor devices. This objective aims at adapting the behavior of sensor devices and networks according to the application's objectives, while respecting sensors' objectives. At this stage of the project, the DIGIHOME platform will implement and demonstrate the benefits of multi-scale adaptations.

Exchanges schedule & estimated budget

In 2011, the French partner will visit the Norwegian partner according to the following plan:
- Romain ROUVOY (associate professor): 2 visits of 10 days (2x 2,200 = 4,400 €)
- Lionel SEINTURIER (professor): 2 visits of 5 days (2x 1,100 = 2,200 €)
- Frédéric LOIRET (postdoc fellow): 1 visits of 10 days (1x 2,200 = 2,200 €)
- Russel NZEKWA (PhD student): 2 visits of 14 days (2x 2,680 = 5,360 €)
- Daniel ROMERO (PhD student): 2 visits of 7 days (2x 1,340 = 2,680 €)
- Gabriel HERMOSILLO (PhD student): 1 visit of 7 days (1x 1,340 = 1,340 €)

In 2011, the Norwegian partner will visit the French partner according to the following plan:
- Frank ELIASSEN (professor): 2 trips of 5 days (2x 1,100 = 2,200 €)
- Roman VITENBERG (associate professor): 1 trip of 5 days (1,100 €)
- Amirhosein TAHERKORDI (PhD student): 2 trip of 14 days (5,360 €)
- Lucas Provensi (PhD student): 2 trip of 14 days (5,360 €)

These visits will be organized into two waves (1 wave per semester) and each visit will include a 1-day collaboration meeting for reporting and planning the SeaS collaboration activities and at least 4-days working group activities for progressing on the selected objectives. We also plan to organize an annual meeting. The cost of each visit is based on the reimbursement rates of the EGIDE PHC programme (600 € per trip and 120 € per day).
