There is provided a communications system comprising an access network node and a plurality of resource limited nodes. The access network node comprises: a control unit operable to estimate a belief on a network condition for a resource limited node of the plurality of resource limited nodes based on network observations and a history profile of the network observations; dynamically update the belief for the resource limited node in the access network node; determine that the severity of the updated belief in the network condition is indicative that a change in sleep duty cycle of the resource limited node is required; determine that correlation between the resource limited nodes within the plurality of resource limited nodes is indicative that a change in sleep duty cycle of the resource limited node is required; and update the sleep duty cycle of the resource limited node to optimize the overall energy consumed in the resource limited nodes while achieving a specific detection threshold.

A capability for flexible communications within an energy-limited wireless system is presented. An energy-limited wireless node includes a communication module configured to switch between a sleep mode in which the communication module is not operable to communicate and an active mode in which the communication module is operable to communicate, a configurable auxiliary receiver configured to initiate switching of the communication module from the sleep mode to the active mode based on detection of a wake-up signal, and a controller configured to control configuration of the configurable auxiliary receiver to operate using an auxiliary receiver configuration. A controller includes a processor and a memory communicatively connected to the processor wherein the processor is configured to determine a configuration for a configurable auxiliary communication module of an energy-limited wireless node, and propagate, toward the energy-limited wireless node, an indication of the configuration for the configurable auxiliary communication module of the energy-limited wireless node.

There is provided a communications network comprising a network node and a resource limited node. The network node comprises a controller operable to estimate an optimal duty cycle for various operating modes of the resource limited node to minimize the overall resource consumption of the resource limited node; and a transmitter operable to notify parameters of the estimated optimal duty cycle to the resource limited node.

Communications system and a method of determining an optimal duty cycle to minimise overall energy consumption

A capability for controlling or facilitating the use of a wireless tag to communicate location tracking information is presented. The capability for controlling or facilitating use of a wireless tag to communicate location tracking information utilizes a wireless tag supporting multiple states in order to control communication of location tracking information. The wireless tag supporting multiple states in order to control communication of location tracking information may be configured to support or facilitate tag-controlled state transitions, gateway-controlled state transitions, infrastructure-controlled state transitions, or the like, as well as various combinations thereof. The multiple states of the wireless tag may specify use of different sets of wireless gateways for communication of location tracking information, use of different protocols for communication of location tracking information, use of different air interfaces for communication of location tracking information, use of different performance parameters for communication of location tracking information, or the like.

A capability for opportunistic forwarding of information using a wireless terminal is presented. An energy limited node includes a wake-up circuit configured to detect a wake-up signal from a wireless terminal where the wake-up signal includes a modulated waveform signal, and a communication module configured to switch, based on a control signal generated by the wake-up circuit, from a sleep mode in which the communication module is not operable to communicate with the wireless terminal to an active mode in which the communication module is operable to communicate with the wireless terminal. A wireless terminal includes a first wireless communication interface configured for communication with a device using a wireless communication protocol, a second wireless communication interface configured for wireless communication with a wireless access node of a wireless network, and a processor configured to support opportunistic forwarding of information between the device and the wireless access node of the wireless network.
