II.1 e-Health
e-Health is a relatively recent term used to designate healthcare practices supported by electronic
processes and communications.
Figure II.1 shows an example of e-Health service configuration.

Figure II.1 – e-Health service configuration
Various types of devices are involved in the provisioning of e-Health services. Some of these
devices only collect data and interact with the network (e.g., heartbeat sensors), others can interact
bidirectionally (e.g., cameras), some devices usually generate small amounts of data
(e.g., thermometers), while others may deal with multimedia streaming (e.g., cameras) or, deal with
call session control (e.g., SIP terminals supporting video calls). Some devices may even work as
both gateway and sensor-like service platforms.
The e-Health devices gather data and send them to the relevant parties, such as the e-Health centre
in Figure II.1. Hospitals, doctors and families can subscribe to the service to get raw or processed
data.
The devices associated with patients can access the network directly or via a gateway(s) (e.g., home
gateway or a gateway worn on the body):
1) When the patients stay in an indoor environment, the devices can access the network via a
single static home gateway or via multiple dynamic home gateways (in this second case the
patients can move and access the network via different gateways).
2) When the patients are outdoors, the devices can access the network directly via a mobile
network or indirectly via the gateway worn on the body.
The following technical challenges need to be considered for e-Health:
– Grouping should be supported. This is useful, for instance, for multiple patients with the
same type of disease, or in the case of a single patient, to manage a set of devices which can
be managed in group mode.
