Node Device Power Save Service for Ad-Hoc Infrastructure Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, node devices face challenges in conserving power while simultaneously operating in both ad-hoc and infrastructure modes, as they need to manage data communications over shared or different channels, leading to inefficient power save modes and increased battery consumption.
Innovation Solution
Implementing a node device with an ad-hoc interface and an infrastructure interface that includes a power save service to minimize device communication mode by switching between communication channels and optimizing the power save mode through time synchronization and channel management, allowing for simultaneous operation in both networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a node device operates in both ad-hoc and infrastructure modes simultaneously, then communication versatility is improved, but power consumption increases
Solution Approach 1:
The node device alternates between active communication mode and power save mode in periodic cycles. During active periods, the device communicates with both ad-hoc and infrastructure networks; during power save periods, it enters sleep state. This periodic operation allows the device to maintain communication versatility while reducing average power consumption through structured sleep-wake cycles.
Solution Approach 2:
The device dynamically adjusts its operational state based on communication requirements. It transitions between different modes (active, power save, channel switching) depending on whether ad-hoc or infrastructure communication is needed. This dynamic adaptation allows the device to maintain versatility while optimizing power consumption by being active only when communication is required.
2Adaptability or versatility
If the node device switches between communication channels for ad-hoc and infrastructure networks, then communication capability is improved, but device complexity increases
Solution Approach 1:
The node device is designed with universal communication capability that allows it to function in both ad-hoc and infrastructure modes using the same hardware interfaces. The ad-hoc interface and infrastructure interface share common communication resources, enabling the device to operate across different network types without requiring separate dedicated hardware for each mode, thus reducing overall device complexity.
3Use of energy by moving object
If the node device enters power save mode frequently, then energy consumption is reduced, but communication responsiveness deteriorates
Solution Approach 1:
Before entering power save mode, the device performs preliminary actions to notify the other basic service set of its upcoming sleep period. This advance notification allows the network to buffer or schedule communications appropriately, ensuring that when the device wakes from power save mode, it can resume communication quickly without significant delay, thus maintaining responsiveness while still achieving energy savings.
Data Source
AI summary
An infrastructure and ad-hoc node device is described. In embodiments, a node device includes an ad-hoc interface for data communications via an ad-hoc network that includes peer devices of a first basic service set (BSS). The node device also includes an infrastructure interface for additional data communications via an infrastructure network of nodes that communicate via an access point of a second basic service set. A power save service can optimize a power save mode of the node device by minimizing a device communication mode during which the data communications and the additional data communications are received over a shared communication channel, or are received over different communication channels.
