Abstract: In embodiments of the present invention improved capabilities are described for sensing a change in a network topology using a discovery node in a mesh network; transmitting an explore frame, based at least in part on the sensed change, from the discovery node to a destination node using an intermediate node; receiving a response to the explore frame from the destination node; determining at least one functional network route from the discovery node to the destination node based at least in part on route information received in association with the response to the explore frame, wherein the route information includes a node path; and transmitting an instruction to the destination node from the discovery node based on a reverse node path.
Abstract: The present invention relates to a wireless home automation system having controllers for controlling a broad variety of functions via two-way communication with a plurality of devices. More specifically, the invention relates to sharing information related to the system between controllers, e.g. by updating a second controller with the newly learned information of a first controller, or by replicating a controller by making a second controller a complete copy of a first controller. The information can be shared by generating and transmitting, with a first controller, a list of device identifiers of devices controlled by the first controller to a second controller. The list is received by the second controller and stored in a memory of the second controller dedicated to store device identifiers of devices controlled by the second controller. This function proves advantageous when new controllers are introduced or if a controller is lost, worn out, or destroyed.
Abstract: The present invention relates to a wireless home automation system having a controller for controlling a broad variety of functions via two ways communication with a plurality of devices. More specifically, the invention relates to an improved and flexible way of routing signals from a controller to a device which includes the building of various tables such as routing tables. The improved and flexible way of routing allows the user to reach any device within the network with a high reliability. According to the invention, a processing unit of a controller is adapted to instruct a first device to discover other devices within its range by transmitting a signal comprising a device table holding device identifiers of devices controlled by the controller. The devices in the system are adapted to, upon instruction, perform a discovery of other devices within its range by transmitting discovery signals addressed to each device in the device table received from the controller.
