Solution Overview

Problem

In Body Area Networks (BANs), nodes face increased power consumption due to prolonged standby times during unscheduled data communication, where they wait for allocation slots that can shift in time, leading to inefficient battery usage.

Innovation Solution

Incorporating a connection request and assignment frame with an initiative field, allowing nodes to initiate data communication at predetermined timing without waiting for a poll or data frame from the hub, reducing the need for prolonged standby states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a node waits for receiving a poll or data from a hub in a given allocation slot, then data communication can be performed in an organized manner, but the receipt standby time becomes too long and power consumption increases

Engineering Contradiction:
Improvedata communication organizationVSAvoidpower consumption of node
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent inverts the traditional communication initiation role: instead of the hub always initiating communication by sending polls to nodes, the node is empowered to initiate data transmission autonomously by setting the initiative field to '1' in the connection request frame. This inversion allows the node to eliminate prolonged standby waiting for hub polls, directly reducing power consumption while maintaining communication organization through the protocol's connection management mechanisms.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If a node maintains a receivable state until it receives the poll or data from the hub, then it can respond promptly to hub communications, but the standby time results in increase of power consumption

Engineering Contradiction:
Improveresponse to hub communicationVSAvoidpower consumption of node
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent implements self-service by enabling the node to autonomously initiate data transmission without requiring the hub to send polls. By setting the initiative field to '1' in the connection request frame, the node takes control of communication timing, eliminating the need to maintain a continuous receivable state. This self-service approach allows the node to transition to low-power states more frequently, reducing energy loss while still ensuring timely communication when data needs to be transmitted.

Inventive Principle:
Principle #25Self-service

AI summary

According to an aspect of the present invention, a device for communication according to a specific communication protocol includes a processor for generating a connection request frame for requesting a connection to other device based on the communication protocol. The connection request frame includes a predetermined field. The processor initiates data communication at predetermined timing in a given time interval in the case of setting the predetermined field of the connection request frame to a predetermined value and receiving a connection assignment frame for accepting the connection request from the other device.
