Abstract

In one embodiment, network parameters are dynamically adjusted using weather forecasts. The embodiments include determining a weather forecast that predicts a weather condition proximate to a network. Network parameters are then selected for adjustment based on the predicted weather condition. The selected network parameters are adjusted to improve performance of the network in response to the predicted weather condition.

determining, by a network management server (NMS) or a root node, a weather forecast that predicts a weather condition proximate to a network;
determining a plurality of network profiles that define attributes of the network and correspond to a plurality of weather conditions respectively, wherein the attributes of the network include application traffic profiles and application usage requirements
selecting, by the NMS or the root node, network parameters of the network to adjust based on the predicted weather condition and a corresponding network profile;
selecting nodes of the network based on the predicted weather condition; and
dynamically adjusting, by the NMS or the root node, the network parameters to improve performance of the network in response to the predicted weather condition, wherein the network parameters at at least a link layer and a network application layer across an entire networking stack are dynamically adjusted, wherein the adjusting of the network parameters only affects the selected nodes of the network.

2. The method according to claim 1 ,
wherein the selecting of network parameters is based on the selected network profile.

3. The method according to claim 1 , wherein the adjusted network parameters include parameters from a plurality of layers in a network stack of the network.

predicting future energy resources of an energy harvesting device connected to the network based on the predicted weather condition, wherein
the adjusting of the network parameters is based on the predicted future energy resources.

6. The method according to claim 1 , further comprising:
receiving a message that indicates attributes of a network device that is subject to be affected by the predicted weather condition, wherein
the adjusting of the network parameters is based on the attributes of the network device.

7. The method according to claim 1 , further comprising:
determining a time period during which the network parameters are to be adjusted, wherein
the network parameters are adjusted during the determined time period.

obtaining feedback on network performance during or after a time at which the predicted weather condition occurs; and
adjusting a network profile based on the obtained feedback.

9. The method according to claim 1 , wherein the root node is a Field Area Router (FAR).

10. The method according to claim 1 , wherein the network is a low power and lossy network (LLN).

11. An apparatus, comprising:
at least one network interface that communicates with a network;
a processor coupled to the at least one network interface and configured to execute a process; and
a memory configured to store program instructions which contain the process executable by the processor, the process comprising:
determining a weather forecast that predicts a weather condition proximate to the network;
generating a plurality of network profiles that define attributes of the network and correspond to a plurality of weather conditions respectively, wherein the attributes of the network include application traffic profiles and application usage requirements;
