Technical Objectives

IPAC aims at delivering a middleware and service creation environment for embedded, intelligent, collaborative, context-aware services in mobile nodes

IPAC scope: diverse applications in a collaborative nomadic environment

IPAC services will be supported by knowledge and ontology engineering techniques, dealing with interoperability, integration, and re-configuration/adaptation issues

IPAC Key Enablers

Autonomic Computing in Mobile Ad-hoc environments

Sensing components to realize context awareness

Short Range Communications (SRC) to materialize a highly distributed architecture

Reliable and efficient information dissemination algorithms: Rumor (epidemical) Spreading

Embedded Service/Application modeling and provision

Collaborative context-awareness

IPAC Middleware Architecture

Structure: service layer, storage layer, application layer.

Development technologies: a Java-based, lightweight container for dynamic software components.

Possible implementation technology: Open Services Gateway initiative (OSGi).

Two possible implementation approaches: a custom OSGi-like architecture customization of existing open OSGi

implementation according to the IPAC requirements.

Information Dissemination

Epidemical model and algorithms for information dissemination Gossiping, re-configurable controlled flooding

Collaborative context discovery, reasoning and dissemination

Incentive mechanisms for effective collaborative dissemination of information and context Game theory, transparent punishment,

membership management protocols

CCC

ipaKnowledge-based framework for re-configurability and interoperability

In-node knowledge management infrastructure caters for:

modeling possible situations (i.e., context) of the IPAC node/system,

storing situation-information, reasoning over contextual data, identifying possible conflicts in the system, inferring new information based on sensor

data, disseminating inferred information to

interested parties.

IPAC Configurations Communicating Entities:

Relaying Nodes: transmit / receive and process info - limited sensing and storage capabilities,

End Nodes: receive or transmit, assess and, potentially, exploit the exchanged information.

Many different configurations are possible: Node-node communications User-node communications Sensor-node-communications

IPAC Trials

IPAC will be demonstrated through 3 trials1. IPAC in Industrial Environments

• Process monitoring & control in CRF plant• Autonomic communications between machines, workers

& technicians 2. IPAC in Humanitarian Relief Operations

• Simulated crisis management scenarios (e.g., relief force establishment)

• Secure ad-hoc communications and coordination in crisis zones

3. IPAC in Intelligent Transportations • Detection of snow/fire/accidents and dissemination of

alerts• Based on a vision sensor

Evaluation criteria: Performance, Reliability, Efficiency

Industrial Application

Process and quality monitoring in industrial environments

Industrial Application

Monitoring and improvement of the component distribution process Components are transferred to an expedition floor

and are further loaded to trailers Nowadays this is a quite error-prone process

Barcode-based identification, static expedition floor cells’ allocation, false component loading/unloading

IPAC goals RFID-based tracking of transported components WSN-based localization of components Dynamic expedition floor allocation Infrastructure-less monitoring by human supervisors Eventually, less faults during the process
