摘要： Proposed is a network node (102) for a mesh network (100). The network node comprises a processing unit (202) adapted to determine an indicator of reliability of the network node. The network node also comprise a control unit (220) adapted to configure the network node to operate in either a router configuration or an end-node configuration based on the determined indicator of reliability of the network node. The network node may thus adapt its configuration based on its reliability.

摘要： A wireless mesh network system includes network nodes that operate in blink and canopy modes of operation. In operation, a network manager joins nodes operating in the canopy node to the network and allocates network bandwidth to the canopy nodes. The allocated bandwidth includes a first bandwidth allocated for transmitting and receiving data packets between canopy nodes that are joined to the network, and a second bandwidth allocation for receiving network joining messages from nodes that are not joined to the network. The second bandwidth allocation is also used for receiving data messages from nodes operating in the blink mode. Thus, in response to receiving a message that was transmitted from a blink node to a canopy node using the second bandwidth allocation, the network manager identifies the message as a data message and provides the data from the message to a host application.

摘要： Upon communication nodes receiving data that is a transfer target, based on a link value corresponding to a communication quality of each communication node that has transferred the data and radio wave strength among the communication nodes, a network system calculates a total link value that indicates a quality of a communication path that is used to transfer the data. The network system determines whether the calculated total link value is greater than or equal to a threshold value and based on a determination result, transfers the data to a destination communication node.

摘要： In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.

摘要： Methods and network nodes (700-720) route communications between pairs of source and destination nodes through network nodes (700-720) of a wireless communication system. One resource slot of a wireless communication link is selected (1200) between each of a sequence of the network nodes (700-720) along a communication route between one pair of the source and destination nodes. Another resource slot of the wireless communication link is selected (1202) between at least some of the sequence of the network nodes (700-720) along the communication route between the one pair of the source and destination nodes. Selection of the other resource slot between each of the sequence of the network nodes along the communication route can be constrained to selection among resource slots that are available from only the sequence of the network nodes along the communication route between the one pair of the source and destination nodes.

摘要： In a conventional configuration, it is necessary to install all radio terminals and search a route based on a fixed condition, which makes it difficult to provide a balance between an enlarged communication area and economic efficiency of a system. In a meter interface (150), a demodulator unit (156) demodulates installation information transmitted from a concentrator (100) on a regular basis, a connected target determiner unit (158) searches an upper terminal to be connected based on a threshold pre-stored in a memory unit (157), and control is executed such that when the obtained electric field intensity level is higher than a threshold, a concentrator connected with meter interfaces of a smallest number is connected to the meter interface, while when the obtained electric field intensity level is lower than the threshold, a concentrator having a highest electric field intensity level is connected to the meter interface.
