In one embodiment, a management device in a computer network determines when nodes of the computer network join any one of a plurality of field area routers (FARs), which requires a shared-media mesh security key for that joined FAR. The management device also maintains a database that indicates to which FAR each node in the computer network is currently joined, and to which FARs, if any, each node had previously joined, where the nodes are configured to maintain the mesh security key for one or more previously joined FARs in order to return to those previously joined FARs with the maintained mesh security key. Accordingly, in response to an updated mesh security key for a particular FAR of the plurality of FARs, the management node initiates distribution of the updated mesh security key to nodes having previously joined that particular FAR that are not currently joined to that particular FAR.

A wireless communications system includes a base station, a plurality of intermediate devices, and a terminal device. Downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define an uplink route from the terminal device to the base station via one or more intermediate devices. Power is conserved at the terminal device on the uplink because a lower power transmission can be used which although insufficient to reach the base station can reach the intermediate device.

WIRELESS NETWORK CONFIGURATION

Номер: US20180063726A1

In a wireless network formed of short range femtocells, each femtocell provides wireless connectivity to user equipment devices and the user equipment can move around the topographical range covered by the network by handing over to a neighboring femtocell. Due to the limited range of a femtocell, there will be coverage gaps. If the device moves to a location not covered by a femtocell, it will try to connect to a macrocell of a different wide area cellular network until it is within range of another femtocell network. To minimize handovers from the femtocell network to the macrocell network, each femtocell is arranged to analyze historic log data to detect coverage gaps experienced by the user equipment as it moves along a user equipment route and try to close the gaps by increasing the coverage range of femtocells on either side of the coverage gap to close the gap. 1. A method of operating access points in a wireless network comprising:i) identifying a user equipment route in the wireless network, the user equipment route relating to a trajectory of at least one user equipment through a topographical area covered by the wireless network, by processing a historic log recorded by at least one user equipment relating to previously connected access points in the network;ii) identifying at least one coverage gap within the identified user equipment route by locating events in the historic log relating to disconnections from the wireless network between at least two access points; andiii) closing the at least one coverage gap by increasing a coverage range of at least one of the at least two identified access points so that coverage ranges of the at least two access points overlap.2.

The method of routing for wireless ad hoc and sensor networks is a routing protocol that uses a greedy approach, selecting the best route having the maximum remaining energy above a pre-defined threshold limit. The method of routing for wireless ad hoc and sensor networks is an energy efficient routing protocol, in that the routing path is selected to maximize the lifetime of an individual source-destination pair by selecting a route between them that is based on the energy levels of neighboring nodes, without requiring an energy-intensive network flooding approach. The routing path between a source node and a destination node is selected by choosing, at each node, a neighboring node that has the greatest remaining energy level.
