Abstract

A method of route prediction and device configuration for enhancing data transfer across a wireless network arrangement by using routing information to predict data transfer routes and configuring devices to switch between states to reduce data transference time and power consumption of a wireless network arrangement.

Claims

1. A method of wirelessly transferring data across a network between a sending network device (1) and a target network device (5) via one or more intermediate network devices (3, 4), collectively “

the devices”

(1, 3, 4, 5), comprising the steps of;

transmitting an outgoing message (2) from the sending device (1) to the target device (5) via one or more intermediate devices (3, 4);

transmitting an incoming message (2a) from the target device (5) to the sending device (1) via one or more intermediate devices (3, 4);

storing routing information (7) relating to the devices used to successfully transfer the outgoing (2) and incoming (2a) messages;

incorporating the routing information (7) into a second outgoing message to specify a predicted route of intermediate devices intended to be used in the transmission of the second outgoing message so that only the intermediate devices intended to be used in the transfer of data switch to an active state for data communication on receipt of the second outgoing message; and

configuring the intermediate devices used in the transmission of the second outgoing message from the sending device (1) to the target device (5) to remain in an active state until the intermediate devices receive and subsequently transfer an incoming message from the target device (5) to a further intermediate device along the predicted route to the sending device.

2. The method according to claim 1, further comprising:

a means of sending and receiving data between the devices within the network arrangement including but not limited to a wireless mesh network arrangement.

3. The method according to claim 1, further comprising:

a means of configuring the devices to be capable of receiving and sending data based upon the prediction that the devices will be subsequently required for data communication.

4. The method according to claim 1, comprising:

a means of retrieving routing information derived from successful communications within the wireless network arrangement, from the sending device, target device and/or any other wireless network device.

5. The method according to claim 1, comprising:

a means for establishing alternative communication pathways within a network arrangement which may be utilized if a predicted communication pathway become unviable for effective data transfer.

6. The method according to claim 5, comprising:

a means for allowing multiple data transfer routes to be established within the network arrangement.

7. The method according to claim 1, wherein said method comprises the step of determining different successful communication routes.

8. The method according to claim 1, wherein said method is capable of allowing configuration of any of the devices in order that they may remain capable of detecting and responding to messages or signals sent by any other devices within the wireless network and further independently assess the requirement for participation in data transfer and responding accordingly.
