Wireless sensor network system, and device and method thereof

1 . An arrangement suitable for a mobile local wireless network, the arrangement comprising:

at least one sensor node configured to transmit sensor measurement data via at least one long-range wireless network, and to transmit the sensor measurement data and to receive at least beacon signals via short-range communication; and

a gateway configured to

facilitate a local short-range wireless network,

receive at least the sensor measurement data via the short-range wireless network,

connect to an in-situ computing device, comprising one or more processors configured to obtain the sensor measurement data via the gateway from the at least one sensor node, the in-situ computing device being configured as a user-operated device, and

send beacon signals in response to a manual initiation by a user or when a coverage of the at least one long-range wireless communication network that is currently-used is weak or missing,

wherein, at receival of one of the beacon signals at the at least one sensor node, the at least one sensor node switches to using only the short-range wireless communication network to send the measurement data and terminates using the at least one long-range wireless communication network to transmit data, in accordance with commands received from the gateway or as long as a beacon signal is detected at the at least one sensor node.

2 . The arrangement of claim 1 , wherein the gateway is connected to the computing device via a short-range wireless communication system, or by a wired connection.

6 . The arrangement of claim 1 , wherein the gateway is a dongle device connected to and essentially operated by the in-situ computing device.

7 . The arrangement of claim 6 , wherein the gateway is a mobile modem connected to and at least partly operated by the computing device.

8 . The arrangement of claim 6 , wherein the at least one sensor node is configured to use long-range wireless networks when a beacon signal is not detected at the sensor node for a period of time.

9 . The arrangement of claim 1 , wherein the gateway is a mobile modem connected to and at least partly operated by the in-situ computing device.

10 . The arrangement of claim 9 , wherein the at least one sensor node is configured to use long-range wireless networks when a beacon signal is not detected at the sensor node for a period of time.

11 . The arrangement of claim 1 , wherein the at least one sensor node is configured to use long-range wireless networks when a beacon signal is not detected at the sensor node for a period of time.

12 . The arrangement of claim 1 , wherein the computing device is a mobile device, a computer terminal, or an in-vehicle computing device.

13 . The arrangement of claim 1 , wherein the computing device is configured to communicate with an external server to send sensor measurement data to the external server.

14 . The arrangement of claim 1 , wherein the measurement data from the sensor nodes is presented at the computing device to a user.

15 . The arrangement of claim 1 , wherein the measurement data from the sensor nodes is used to form an alarm at the computing device to a user.

16 . A gateway usable for a mobile wireless network, the gateway comprising:

one or more processors configured to:

facilitate a short-range wireless network, and

connect with a computing device configured as a user-operated device,

wherein the gateway is configured to transmit beacon signals in response to a manual initiation by a user or when a coverage of the at least one long-range wireless communication network that is currently-used is weak or missing, to provide sensor nodes with a signal to cause the respective sensor nodes to switch to transmitting data using only the local short-range wireless network and to terminate using long-range wireless networks to transmit data, in accordance with commands received from the gateway or as long as a beacon signal is detected at the sensor nodes, the gateway being further configured to receive data from the sensor nodes, and transmit received sensor data to the computing device.

17 . The gateway of claim 16 , wherein the gateway is further configured to transmit data from the computing device to the sensor nodes.

18 . The gateway of claim 16 , wherein the short-range wireless network comprises one or more of IEEE 802.11, IEEE 802.15.1, and ISM/SRD band wireless communication network.

19 . A method for a mobile local wireless network, the method comprising:

sending at least one beacon signal from a gateway to one or more sensor nodes in response to a manual initiation by a user or when a coverage of at least one long-range wireless communication network that is currently-used is weak or missing;

receiving one of the at least one beacon signal at one of the sensor nodes;

at receival of the one beacon signal at the one sensor node, switching, by the one sensor node, to using only a short-range wireless communication network to send measurement data and terminate using the at least one long-range wireless communication network to transmit data, in accordance with commands received from the gateway or as long as a beacon signal is detected at the one sensor node;

sending the measurement data from the gateway to a connected computing device configured as a user-operated device; and

providing the measurement data at or via the connected computing device.
