Abstract
Provided herein a system and a method that may include the following steps: receiving data from one or more sensors configured to measure one or more predefined metrics of an infrastructure; establishing a wireless channel with a wireless network; obtaining time-varying characteristics of the wireless network; and determining a series of transmission time slots for transmitting the data received from the sensor, based on the time-varying characteristics, for reducing overall power consumption of the data transmission.
Claims20
A method of reducing power consumption at a transmission node being a part of a wireless network, the method comprising:
- obtaining by at least one transmission node, physically connected to at least one sensor, data from the at least one sensor configured to measure at least one physical metric;
- establishing a wireless channel between said transmission node and a wireless network;
- obtaining, at said transmission node, time dependent parameters indicative of a power consumption of transmission of said obtained data by said at least one transmission node to said wireless channel;
- and
- determining a series of transmission time slots for transmitting said obtained data by said transmission node, based on said time-varying characteristics, for reducing the power consumption caused by the data transmission by said transmission node.
A method of reducing power consumption at a transmission node being a part of a wireless network, the method comprising:
- obtaining by at least one transmission node, data from at least one sensor configured to measure at least one physical metric of an infrastructure system;
- establishing a wireless channel between said transmission node and a wireless network;
- obtaining, at said transmission node, time dependent parameters indicative of a power consumption of transmission of said obtained data by said at least one transmission node to said wireless channel;
- and
- determining a series of transmission time slots for transmitting said obtained data by said transmission node, based on said time-varying characteristics, for reducing the consumption caused by the data transmission by said transmission node,
- wherein the series of transmission time slots for transmitting are determined by finding a shortest path over a directed acyclic graph (DAG) whose nodes denote valid transmission time slots and edges are associated with a cost, in power consumption terms.
