Benefits of technology

The present patent is about a wireless communication device that can operate in a mesh network and control or monitor the state of remote objects within the network. The device can transmit data packets and dummy data packets to mimic the pattern of transmission of the first data packets. The device can also determine an activity profile that characterizes the pattern of transmission of the first data packets and use it to transmit dummy data packets. The dummy data packets can be transmitted at an average transmission rate that is higher than the average transmission rate of the activity profile. The device can operate according to the Bluetooth Low Energy protocol and the mesh network can be an ad-hoc network. The technical effect of the patent is to provide a device that can reliably control or monitor the state of remote objects within a mesh network.

Problems solved by technology

It the communication equipment is low-powered, it may not have a communication range sufficient to communicate directly with other equipment located in the network.
That is, devices spread across the network over a large distance compared to the communication range of the attached equipment may not all may be able to communicate directly with each other.
Unfortunately, such a profiling of the network traffic can lead to situations in which security may be compromised.

Embodiment Construction

[0042]Embodiments of the present disclosure are directed to wireless communication devices operating within a mesh network that can operate so as to obscure changes to the network traffic. By making it more difficult to identify changes to network traffic, the security of the environment within the coverage area of the network can be increased.

[0043]Embodiments of the present disclosure relate to a wireless communication device that can operate according to a wireless communication protocol. The wireless communication device is part of a mesh network comprising a plurality of other remote devices. The wireless communication device can communicate as part of the mesh network by transmitting data packets to, and receiving data packets from, other devices that are part of the mesh network. Within the mesh network, a device may operate as a relay device by re-transmitting received data packets.

[0044]The wireless communication device can process data packets to execute instructions conta...

Abstract

A wireless communication device capable of operating according to a wireless communication protocol and capable of operating in a mesh network, the device being configured to: at a first time transmit data packets in accordance with a mesh network protocol; determine an activity profile that characterises the pattern of transmission of those data packets from the communication device; and subsequently transmit dummy data packets in accordance with the mesh network protocol so as to adopt an activity profile that mimics the determined activity profile.

Description

TECHNICAL FIELD[0001]This invention relates to preventing traffic analysis of a communication network.BACKGROUND OF THE INVENTION[0002]Increasing numbers of devices are being networked together so as to be able to transmit and receive messages between themselves. For example, in the home, it may be desirable for multiple devices to be able to communicate with each other and also potentially with the internet in order to allow for an automated control of the home. For example, a home may contain a lighting system, heating appliances and sensor devices. By allowing these devices to communicate with each other certain controls can be automated, such as turning on the lights and the heating when the sensor detects that a user has entered a room.[0003]In general, when devices are connected in this way, one device may undertake a certain action in response to determining that another device is in a particular state. This intercommunication of diverse devices / appliances within a network fo...
