Why Akogrimo? - Grid and Networks – not a business proposition yet

Grid Middleware is network agnostic – the net is simply there

Grid Middleware is unaware of Mobility and Pervasiveness

Grid Middleware ignores cross-layer cooperation in modern networks

Grid Middleware is not prepared for the network revolution

Grid is not interesting for network operators – no business model for them.

And so …. To join Grid Middleware and “The mobile Internet of tomorrow” ….

Vision

Grid services:– To be pervasive

• Anyone, anywhere, any time

• fixed or mobile

– personalised knowledge and semantics

– To allow for:• Ad hoc, dynamic and

cross-organisational federations

– To solve complex scenarios in everyday life

For network and service operators:

– To extend their scope by developing new, business services and value added chains.

eLearning testbed

Advanced Grid Research Workshops through European and Asian Co-operation 10

Challenges of eLearning field trip

Grids:– On demand formation

of student groups– Sharing of data from

several separately administered sources securely

– Common agreed interfaces for diverse equipment

Mobility:– Changing physical

location of student nodes

– Mobile sensors and receipt of multimedia

– Relocation of some higher Grid services from fixed to mobile equipment

Advanced Grid Research Workshops through European and Asian Co-operation 11

eHealth testbed - more detail on this

Early recognition of heart attacks or strokes and provision of proper treatment as soon as possible– So, monitor patients with a risk of heart attack or stroke. – Activate emergency when required, along with monitoring history

In more detail:– Patient at risk has monitoring equipment communicating with

mobile– Patient is registered with heart monitoring and emergency service

(HMES)– Locate and direct emergency forces or first responders nearby to

the patient– Collect, analyze and interpret patient data before arrival in

hospital– Enable access and intelligent filtering of patient records– Combine in an intelligent way live data (e.g. cardiograms) with

patient history and simulations– Dynamic Workflows based on results or human intervention– Services range from information retrieval over computational

analysis service to information interpretation and filtering.

eHealth testbed

Advanced Grid Research Workshops through European and Asian Co-operation 14

Challenges from eHealth test bed - a selection

Grids:

– Creation of VO on demand

– Integration of patient data from multiple separately administered sources securely

– Multiple autonomous conventional organisations

– Services from several conventional organisations

Mobility:– Monitoring of patients

at risk wherever they are

– Patient’s electronic smart card

– Access to experts’ knowledge whereever they are

– Access to equipment in the emergency vehicle

video

eHealth video – 3 minutes

Note – eHealth video was made before prior monitoring of patients at risk was included in the test bed planning

Advanced Grid Research Workshops through European and Asian Co-operation 16

Selected technical considerations

Operational VO on demand for running workflows: inherits providers, roles, responsibilities, rights and restrictions already set up in parent VO.

Service discovery and negotiation within workflow execution timeframe

Policies for VO Management, SLA, security

Security at Grid level to interwork with A4C

Signalling and message delivery both available

Presence detection

Context determination (on next slide)

Mobile IPv6: allows roaming with minimal disruption

Advanced Grid Research Workshops through European and Asian Co-operation 17

Examples of Context

#User:

– Profile: e.g. contact details, preferences

– Current role

– Presence

– Location

Locally available services:

–

Device:– Screen– OS– Installed s/w

Context may influence workflow behaviour

Role of Akogrimo in the EU Grids programme

Some collaboration task leaderships

In particular, standards analysis resulting from EU Grid Projects:– NextGrid and Akogrimo provide co-chairs– Strategy Group - includes Jamil Appa, one of

today’s SIMDAT speaker– Idea is to focus efforts of the Grids projects,

so that Europe’s voices are heard – First phase of information gathering

Advanced Grid Research Workshops through European and Asian Co-operation 19

Collaboration prospects

Is there a role for collaboration by non-European partners within Akogrimo?– Not originally envisaged in project plan and budget– A call (within Europe) is being made for a partner to

represent the interests of a 3rd test bed – application: disaster response

– Possible roles for unanticipated institutions – note - not discussed with consortium:• Further requirements analysis for mobile grids

• Host visiting researchers or implementors

• Solutions previously unknown to us

– Possible confidentiality issues (e.g. European telecom operators)
