From Personal Area Networks to Personal Networks

Personal Area Network (PAN)

Network connecting devices in the close vicinity of a person/personal entity → local scope

Personal Network (PN)

Overlay network on network infrastructure in reach connecting devices of a person/private entity independent of their location

• User centred • Secure and trustworthy• Virtual vicinity of local and remote devices• Self-organisation of network connections• Heterogeneity of technologies

Some Predictions• By 2010: 40 percent of all potentially networkable electronic or electromechanical devices

will be connected (Harbor)• 1000 wireless devices/person by 2017 (WWRF)

Ecma TC32 activities on Personal Networks

Decision to start a TC32 Editor Group on ‘Personal Networks and their Federations (PNF)’ in August 2008

Chartered to produce four Technical Reports on analysing standardization needs:

• Umbrella TR, editor E. Onur, TU Delft

• Networking TR , editor M. Jacobsson, TU Delft

• Enabling Services TR, editor tbd ,

• Federations.TR, editor tbd

Collaboration with TC32-TG17 (IP-based Communications)

Involved companies/organisations:

Need for PN&F

• Environment of potentially wireless connected mobile equipment around the use, ever increasing and very dynamic in nature

• User having with-me and not-with-me, at home, in the car, in the office, in the 2nd home . . .

• Need for a simple and secure way of sharing resources with colleagues, business partners, friends, family members, etc.

What PN&F provides

• PN brings the with-me and not-with-me together (when physically and economically possible)

• PN handles the dynamic aspects of the local and non local devices, and presents an abstracted simplified image to the outside world (a complex terminal with fixed and variable capabilities)

• PN Federation provide a simple and secure method to share resources with a given user or group of users

PN&F relevance and the relation with service providers

• The PN can provide to a service provider a stable abstraction with a defined quality of service, that allows the service provider a simpler and more stable working environment than the dynamic user and or home network environment

• The PN provides to a telecom service provider in addition the possibilities to provide services like:

• Interconnection of PN clusters

• Management

• Data and/or network back/up services

• The PN can be for the mobile environment what the combination of router (with NAT) - LAN/Wireless-LAN has done for xDSL: the connection of simple home networks

• PN includes ‘peer-to-peer’ networking within the PN, Federation adds secured ‘peer-to-peer’ networking across PNs

PN&F applications in the eHealth domain

• BAN architecture (body area network with sensors and device taking on gateway function)

• Near person networks, e.g. for tele-monitoring

• Organisation of home network infrastructure with overlay(s) for eHealth applications

• eHealth / eWellness applications

• Federation = cooperation of a set of independent networks under mutually agreed rules for cooperation

• Overall authority only for the time and purpose of the federation. Examples:

• Sharing personal resources

• Emergency networks

• Virtual meeting

• Virtual education

• Use of a subset of the total resources• Driven by purpose or by opportunity• Full ad hoc or with support from infrastructure
