Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication networks with battery-powered nodes are expensive and time-consuming to maintain due to frequent battery replacements, while externally-powered networks rely on costly electrical power sources.
Innovation Solution
Implementing a system with a leader node that alternates between awake and sleep modes to reduce power consumption, where follower nodes transition between these modes synchronously, thereby minimizing power usage when not actively communicating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery-powered nodes are used in communication networks, then the networks can operate without external power sources, but the batteries must be frequently replaced which increases maintenance costs and time
Solution Approach 1:
The patent implements periodic sleep and awake cycles for network nodes. During sleep mode, nodes consume minimal power from their batteries, while during awake mode, they actively communicate and perform sensing functions. This periodic operation extends battery life significantly, reducing the frequency of battery replacements and lowering maintenance costs while maintaining network functionality.
2Ease of operation
If externally-powered nodes are used in communication networks, then battery replacement issues are eliminated, but the networks consume electrical power from external sources which increases operational costs
Solution Approach 1:
The system employs periodic sleep and awake modes where nodes alternate between low-power consumption state and active communication state. This reduces overall energy consumption from external power sources while maintaining network functionality during awake periods, thereby lowering operational costs without requiring extensive maintenance infrastructure.
Solution Approach 2:
The network nodes autonomously manage their own power consumption by implementing sleep and awake cycles without requiring external intervention. Each node independently transitions between power states based on network requirements, eliminating the need for manual battery replacement while minimizing external power consumption through intelligent self-regulation.
3Reliability
If all nodes remain in awake mode to ensure network functionality, then communication reliability is maintained, but power consumption increases significantly
Solution Approach 1:
Nodes alternate between sleep and awake modes in periodic cycles. During awake mode, nodes are fully functional and can communicate reliably. During sleep mode, nodes consume minimal power but can be quickly awakened when network communication is needed. This periodic operation maintains communication reliability while dramatically reducing average power consumption compared to continuous awake operation.
Solution Approach 2:
The system uses feedback mechanisms where nodes monitor network conditions and adjust their sleep and awake cycles accordingly. When network activity is detected or required, nodes transition to awake mode. When no communication is needed, nodes enter sleep mode. This feedback-driven approach ensures reliable communication when needed while minimizing power consumption during idle periods.

AI summary
The present disclosure generally relates to systems and methods for reducing power consumption in communication networks. In one exemplary embodiment, a system includes a leader node in communication with a plurality of follower nodes. The leader node causes the leader and follower nodes to transition from an awake mode to a sleep mode where they consume less power. An exemplary embodiment of a method includes the steps of configuring nodes in a communication network as follower nodes and configuring a node in the communication network as a leader node. The leader node is configured to cause the leader and follower nodes to alternate between an awake mode and a sleep mode. The leader and follower nodes consume less power when in the sleep mode than when in the awake mode.
