Report Timing Control Method for Monitoring WSN Applications

Abstract

Wireless sensor network (WSN)-based monitoring application services frequently involve random installation of multiple sensor nodes in the monitoring area, allowing the nodes to transmit data periodically. However, this generates unnecessary and redundant data, causing an increase in data packet collision. This is because multiple sensors installed at similar locations will transmit the same data. Thus, this study proposes a method that enables each sensor node to autonomously determine data transmission time using only its local information. Through simulations, we verified that the proposed technique could control both unnecessary and redundant data transmission and data collision.
