A COMMUNICATIONS SYSTEM, AN ACCESS NETWORK NODE AND A METHOD OF OPTIMISING ENERGY CONSUMED IN A COMMUNICATION NETWORK
First Claim
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.

Abstract
The access network node includes a control unit operable to estimate a belief on a network condition for a resource limited node of a 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 improve or optimize the overall energy consumed in the resource limited nodes while achieving a specific detection threshold.
