Solution Overview
Problem
Existing sensor networks face challenges in setting up a new network efficiently, particularly in conserving energy reserves, as self-examination for synchronization and data exchange is complex and energy-intensive.
Innovation Solution
A method where initial information is provided by a mobile installation device to newly installed sensor nodes, avoiding energy-intensive self-examination by using the installation device to transmit necessary time and clock synchronization information, allowing sensor nodes to determine optimal data exchange windows without expending energy.

Engineering Contradiction Analysis
1Extent of automation
If sensor nodes perform self-examination for synchronization and data exchange, then the network can be set up autonomously, but energy consumption increases significantly
Solution Approach 1:
A mobile installation device is introduced as an intermediary to perform the energy-intensive self-examination and synchronization tasks on behalf of the sensor nodes. The installation device collects timing information from existing sensor nodes and transmits this pre-processed information to new sensor nodes, eliminating the need for new nodes to perform autonomous self-examination and thereby conserving their limited energy reserves while still achieving autonomous network integration.
2Reliability
If sensor nodes open receiving windows for extended periods to ensure synchronization telegram reception, then data exchange reliability improves, but energy consumption increases
Solution Approach 1:
The mobile installation device performs preliminary actions by collecting timing information from existing sensor nodes before new sensor nodes are activated. This pre-collected timing information allows new sensor nodes to immediately open their receiving windows at the correct time without needing to extend the window duration for trial and error synchronization, thereby ensuring reliable telegram reception while minimizing energy consumption.
3Adaptability or versatility
If new sensor nodes determine timing information through self-examination, then network independence is maintained, but setup complexity and energy expenditure increase
Solution Approach 1:
The mobile installation device creates a copy of the timing information from existing sensor nodes and transmits it to new sensor nodes. This copying approach maintains network independence because the timing information is derived from actual network nodes rather than predetermined values, while significantly reducing setup complexity by eliminating the need for new nodes to perform complex self-examination procedures.

AI summary
The method involves connecting sensor nodes to one another to transmit sensor data to a central receiving node. Time information is stored in each sensor node from other neighboring sensor nodes lying in the reception area of each sensor node, on the basis of which each sensor node connects to other sensor nodes. Initial information in a new sensor node is formed using sensor node operation initiating information from a mobile installation device, which is transmitted into the new sensor node during installation of the new node.
