Background: This report is written in the framework of the UMOBILE project WP4 “Services enablement”,
task 4.2 “Data Collection and Contextual Inference”. The task dealt with data mining in the networking
context. Specifically, the task has worked upon i) devising mechanisms and tools that assist in the collection
of data from sensors and other sources; ii) working on contextual awareness aspects relevant to networking
in general, and to UMOBILE in particular; iii) the dissemination of the processed data to other UMOBILE
services and modules, to assist in a future optimization of the network operation, based on
contextualization.
A relevant aspect worked in this task is the notion of usage contextualization and service personalization. A
second relevant aspect concerns the capability to infer roaming behaviour in a way that keeps anonymity
and privacy of the user as well as of the device. A third relevant aspect of the task was to understand how to
assist UMOBILE, namely, which modules could benefit of such contextualization operation, and what/how to
integrate this operation in the UMOBILE architecture. A fourth aspect worked upon in this task concerned
deriving relevant guidelines for the community, based on data collection and experimentation.
For the purpose of contextualization, the task started with an analysis of UMOBILE requirements and how to
best fit such requirements when considering data capture on the network. Operationally, the task started
with a model derived from the Senception’s product PerSense TM. Such model has been incorporated into
the PerSense Mobile Light (PML) middleware, a first tool to assist in data capture and understanding sensing
limitations. Based on such product, and derived from an analysis of the UMOBILE use-cases, as well as
derived from an analysis of project requirements, the task then proceeded to propose the UMOBILE
Contextual Manager module, which is specified in this deliverable and which shall be available until the end
of the project as open-source software, technology readiness level 6, in the context of the UMOBILE proof-
of-concept being defined in WP5 (month 36).
This deliverable has the following goals: i) to introduce related literature concerning contextualization
aspects in networking; ii) to describe the relevancy of such contextualization in networking in general as well
as in UMOBILE; iii) to provide the specification of the contextual manager as our proposal for a flexible
networking framework for contextual awareness in NDN/ICN; iv) to describe experiments carried out,
detailing results obtained and the relevancy in the context of networking. |
