Problem: Military networks are Dynamic, Heterogeneous, and Open

Local Net

Challenge: Discover the Emergent Capability within a given network.

Adaptive Service Networks

1) Assets yet to be developed

2) Needs to be discovered

3) Concepts of Operations to evolve

Network Enabled Operations requires declarative modeling

Semantics permit real-time interoperability

Future of Networking

Trend away from the formal enterprise (integrated systems) toward unstructured peers (ad hoc systems) Little hierarchy or structure, systems-of-systems Away from blueprints, away from formal requirements

Houston: a city without zoning“the form of a city is not defined in advance by specifying requirements; rather, a

city emerges and changes over time though the loosely coordinated and regulated actions of many individuals.”

-- Greg Goth

Need for lightweight scripting that supports interoperability

Task Networks

Out of scheduling (Operations Research)

Rather than script the behavior, capture the task relationships

http://manyeyes.alphaworks.ibm.comThis presentation does not address the algorithmic control aspects, but rather the transaction models that support distributed control

Decomposition yields … - role based - policy driven

Motivating Example

Cyber-Physical Systems Information (ground in app) Hardware (ground in device)

Heterogeneous Ontologies

Distributed Computing

Robots

If Robot A sees Red Ball, remove (else leave it alone)

Conclusions

SPARQLMotion builds on SPARQL Query language (Data Access) Rule language (Manipulation) Open semantics (Grammar) Add in Physical groundings (sensors and effectors)

Actionable when coupled with SPIN

The benefit of this approach Operational redundancy, point of failure is spread out Model-driven approach captures task Network Heterogeneous Peers interoperate through policy scripts

A declarative way to script interaction between heterogeneous peers
