1. A wireless network of devices, comprising:
- a relay start device which is a medical sensor device;
one or more intermediate devices, which are non-medical devices acting as relays; and
a relay end device which is a coordinator acting as a gateway to the wireless network, information being communicated wirelessly in use between the medical sensor device and the coordinator via the one or more intermediate devices,wherein the one or more intermediate devices each comprise control means and transmission means, the control means being operable to cause the transmission means of the intermediate device to transmit an indication of connection stability as a function of at least one connection stability parameter of the intermediate device, indicating when the intermediate device is unstable; and
the wireless network further comprises;
reconnection means operable to establish an alternative route avoiding an unstable intermediate device,wherein the coordinator includes decision means operable on receipt of the indication of connection stability from the unstable intermediate device to take the indication into account to decide whether to transmit a stop or sleep command to the unstable intermediate device, causing the intermediate device to stop all transmission and reception,wherein the reconnection means is operable after the indication of stability is transmitted and before the stop or sleep command is issued anda decision of the coordinator to transmit the stop or sleep command to the intermediate device is performed according to a severity of an ongoing medical process and an availability of an alternative route.

12. An intermediate device for use in a wireless network of devices comprising a relay start device which is a medical sensor device, the intermediate device being among one or more intermediate devices which are non-medical devices acting as relays and a relay end device which is a coordinator acting as a gateway to the wireless network, information being communicated wirelessly in use between the medical sensor device and the coordinator via the one or more intermediate devices,
the intermediate device comprising: -
transmission means and reception means; and control means operable to control the intermediate device; wherein the control means is operable to cause the transmission means of the intermediate device to transmit an indication of connection stability to a device coordinator as a function of at least one connection stability parameter of the intermediate device, indicating when the intermediate device is unstable; wherein the wireless network further comprises; reconnection means operable to establish an alternative route avoiding an unstable intermediate device, the reception means is operable to receive a stop or sleep command from the coordinator which includes decision means operable on receipt of the indication of connection stability from the unstable intermediate device and the control means is operable to cause the intermediate device to stop all transmission and reception on receipt of the stop or sleep command, wherein the reconnection means is operable after the indication of stability is transmitted and before the stop or sleep command is issued, and a decision of the coordinator to transmit a stop or sleep command to the intermediate device is performed according to a severity of an ongoing medical process and an availability of an alternative route.

13. A coordinator in a wireless network of devices comprising at least the coordinator, one or more intermediate devices which are non-medical devices acting as relays and a relay end device acting as a gateway to the wireless network, information being communicated wirelessly in use between the coordinator and the relay end device via the one or more intermediate devices, wherein the coordinator comprises:
-
reception means operable to receive an indication of connection stability of the intermediate device from the intermediate device; wherein the wireless network further comprises; reconnection means operable to establish an alternative route avoiding an unstable intermediate device, the coordinator including decision means operable on receipt of the indication of connection stability from the unstable intermediate device to decide whether to transmit a stop command to the intermediate device, causing all transmission and reception to stop, wherein the reconnection means is operable after the indication of stability is transmitted and before the stop command is issued, and a decision of the coordinator to transmit a stop or sleep command to the intermediate device is performed according to a severity of the ongoing medial process and an availability of an alternative route.
