Self-Managed Cell Architecture
ing the current state and context of our SMC will be essential.
Self-configuring and self-healing cells will support application
and management functionality together with robustness.
The need for policy-driven autonomic management has been
highlighted by organisations such as HP and IBM. As we are
investigating policy-driven adaptation for monitoring, know-

We will not develop a new event bus but instead evaluate,
measure and adapt existing systems such as the Elvin Messenger and the Java Messaging Service (JMS).

We will define the architecture and behaviour of generic
SMCs and how they evolve over time. An event bus will be
used to support interaction between the core management
services to provide self-management. It is also necessary to
define how each of the components managed by the event
bus can be dynamically extended and what consistency and
integrity constraints must be preserved during adaptation.

Layered and Federated SMC Structures
Federation and Layering, techniques more commonly utilised in the information systems world,
will be essential in the provision of network services and distributed applications. We will define the interfaces and protocols which support
both types of interaction for a variety of possible administrative domains. Agreement must
be reached on policies and events that can be
exchanged and negotiation and support protocols must be defined. A peer-to-peer discovery
service will be required to support the dynamic
SMC collaborations and the concept of the Service Level Agreement will be extended to cater
for management services. The techniques employed in developing the intra-cell event bus will
be extended to support inter-cell interaction.

SMC Composition
There is a need compose SMCs into
larger structures.
For example,
home-based patient monitoring
systems will integrate non-contact
monitoring that permits the behaviour of patients to be identified,
with the control of home appliances
and medical equipment installed in
their homes.
In composition, the behaviour of
the SMCs controlling a single device
is entirely subordinated to the SMC
which controls the overall system
thus forming a single administrative
domain. The enclosing SMC may
need to “program” the measurements and event correlation within
the nested SMCs.
Furthermore
policies may be imposed on the
nested SMCs, although refinement
of this will be required to the specific services of the nested SMC.
Nested SMCs will be subject to the
policy of the enclosing SMC.

Demonstrators and Evaluation
It will be necessary to demonstrate how SMCs can be specialised for health monitoring.
An SMC-based system will be developed which is capable of monitoring patients over a personal
area network (PAN). Implantable
sensors will communicate with
secondary control devices, passing the data to a non-contact
monitoring system in the patients
home.

A “Health Map” capable of collecting
and analysing data from multiple
sources and sites will be developed.
Sources may include patients, the
environment, medical centres and
geographical statistics etc.
This service could be used to produce a health-map which summarises the health of the nation and,
more critically, used to support data
mining in emergency situations.
