Abstract: In embodiments of mesh network addressing for duplicate address detection, an end device of the mesh network can generate an address identifier that includes an address and time-based information associated with the end device, which is attached to a router device for communication in the mesh network. The address identifier is maintained by the router device as a tuple state of the end device. The end device or the router device can initiate an address query requesting that mesh network devices in the mesh network having a designated address respond with the tuple state that corresponds to the designated address. The end device or router device receives the tuple state of mesh network devices having the designated address in response to the address query, and can then detect a duplicate address of a mesh network device based on the time based information.

Abstract: Securely joining devices to a mesh network using Datagram Transport Layer Security (DTLS) is described. A secure commissioning session is established between a joiner device and a commissioning device of the mesh network, in response to a joiner router receiving a DTLS-ClientHello message from the joining device, which is requesting to join the mesh network, and relaying the received message, encapsulated in a DTLS Relay Receive Notification message, to the commissioning device. The commissioning device transmits commissioning messages to the joining device over the secure session to enable the joining device to join the mesh network. The joiner router receives an indication from the commissioning device, that the joining device is to be entrusted to receive network credentials for the mesh network, and receives a key to securely transmit the network credentials from the joiner router to the joining device to complete commissioning the joining device to the mesh network.

Abstract: In embodiments of mesh network commissioning, a commissioning device of a mesh network can determine steering data for the mesh network, where the steering data is an indication of a device identifier associated with a device that is allowed to join the mesh network. The commissioning device can then propagate the steering data from the commissioning device for the mesh network to one or more routers in the mesh network, and the steering data indicates that a commissioner is active on the mesh network. The commissioning device propagating the steering data enables the one or more routers to transmit the steering data in a beacon message, and the steering data is effective to enable the device associated with the device identifier to identify that the device is allowed to join the mesh network.

Abstract: In embodiments of mesh network commissioning, a commissioning device establishes a secure commissioning communication session between the commissioning device and a border router of a mesh network to securely establish network communication sessions for joining one or more joining devices to the mesh network. The commissioning device can activate joining for the mesh network, and receive a request from a joining device to join the mesh network. The commissioning device can establish a secure joiner communication session between the commissioning device and the joining device, authenticate the joining device using an encrypted device identifier, and join the joining device to the mesh network.

Abstract: In embodiments of mesh network commissioning, a border router receives a petition from a commissioning device to become the commissioner for a mesh network, and commission joining devices to join the mesh network. The border router transmits the received petition to a leader device of the mesh network, and receives a response to the petition from the leader device, where the response indicates acceptance or rejection of the petition. In response to receiving the response to the petition from the leader device, the border router transmits an indication of the acceptance or the rejection of the petition to the commissioning device. An acceptance of the petition by the leader device authorizes the commissioning device to be the commissioner for the mesh network and a secure commissioning session is established.

Abstract: In embodiments of mesh network commissioning, a commissioning device of a mesh network can determine steering data for the mesh network, where the steering data includes an indication of a device identifier associated with a device that is allowed to join the mesh network, and the indication is represented as a set of values in a Bloom filter that represent the device identifier. The commissioning device can then propagate the steering data from the commissioning device for the mesh network to one or more routers in the mesh network. Propagating the steering data enables the routers to transmit the steering data in a beacon message, where the steering data enables the device associated with the device identifier to compare the set of values in the Bloom filter to a second set of values determined at the device to identify that the device is allowed to join the mesh network.

Abstract: In embodiments of mesh network commissioning, a commissioning device of a mesh network can establish a commissioning communication session between the commissioning device and a border router of the mesh network, and also establish a joiner communication session between the joining device and the commissioning device.

Abstract: In embodiments of mesh network commissioning, a joiner router receives a DTLS-ClientHello message from a joining device requesting to join a mesh network, and the received message is encapsulated in a DTLS Relay Receive Notification message that is transmitted to a commissioning device of the mesh network. The joiner router receives a DTLS Relay Transmit Notification message from the commissioning device, and transmits content of the message to the joining device, where the content enables the joining device to join the mesh network. The joiner router receives an indication from the commissioning device that the joining device is to be entrusted to receive network credentials for the mesh network, and receives a Key Encryption Key (KEK) that is shared between the commissioning device and the joining device. The joiner router then transmits the network credentials to the joining device using the KEK to secure communication of the network credentials.

Abstract: In embodiments of mesh network commissioning, a node device in a mesh network receives a commissioning dataset, and compares a timestamp in the received commissioning dataset with a stored timestamp in a commissioning dataset that is stored in the node. The node device can determine from the comparison that the stored timestamp is more recent than the received timestamp, and in response, transmit a message to a leader device of the mesh network, where the message includes the stored commissioning dataset. The leader device accepts the stored commissioning dataset as the most recent commissioning dataset for the mesh network, and propagates the stored commissioning dataset to the mesh network. Alternatively, the node device can determine that the received timestamp is more recent than the stored timestamp, and in response to the determination, update the stored commissioning dataset to match the received commissioning dataset.

Abstract: In embodiments of mesh network commissioning, a leader device of a mesh network receives a petition to accept a commissioning device as a commissioner to commission joining devices to join the mesh network. The leader device can determine whether to accept or reject the received petition, and transmit a response to the commissioning device with an indication as to whether the received petition is accepted or rejected. In response to a determination of the received petition being accepted, the leader device can update an internal state that tracks an active commissioner for the mesh network.

Abstract: A system, a method and a computer readable storage medium for pre-processing data collected from one or more data sources more accurately summarize data. During the pre-processing, multiple raw data are summarized into a pre-processed datum. By using the pre-processed data entries, more accurate trend data may be generated. Alternatively, data entries are indexed and selectively retrieved based on indices. Decimation of data points are performed based on the indices without retrieving all the data sets from the database, reducing the data access time for returning a query result. Additional data sets may also be retrieved efficiently from the database using the indices.

Abstract: A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of proximity of objects. A central computer accumulates the data produced or received and relayed by each module for analyzing proximity responses to transmit through the adaptive network control signals to a selectively-addressed module to respond to computer analyses of the data accumulated from modules forming the adaptive network. Interactions of local processors in modules that sense an intrusion determine the location and path of movements of the intruding object and control cameras in the modules to retrieve video images of the intruding object. Multiple operational frequencies in adaptive networks permit expansions by additional networks that each operate at separate radio frequencies to avoid overlapping interaction. Additional modules may be introduced into operating networks without knowing the operating frequency at the time of introduction.
