1. A communications system comprising an access network node and a plurality of resource limited nodes, the access network node comprising:

  • a control unit operable toestimate 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.
