Area of Science:

• Computer Science
• Geographic Information Systems
• Network Engineering

Background:

• Emerging Sensor Networks (ESNs) extend traditional Web services, enabling direct interaction between sensor devices and the geographic environment.
• The complex interaction between sensor devices and geographic entities presents significant modeling challenges.
• Sensor device services in ESNs are more susceptible to environmental influences than traditional Web services, impacting system performance.

Purpose of the Study:

• To propose a novel Petri Nets-based modeling method for the interaction between sensor devices and the geographic environment in ESNs.
• To address the challenges in modeling the complex, environment-sensitive interactions of sensor services.
• To improve the performance of sensor application systems by considering response time, fault tolerance, and resource consumption.

Main Methods:

• Classification of IoT services into Sensing and Controlling services based on interaction with geographic entities.
• Classification of GIS services into data and processing services.
• Design and analysis of service algebra and Colored Petri Nets (CPN) models for geo-features, IoT services, GIS services, and their interactions.

Main Results:

• A novel Petri Nets-based modeling method was developed for sensor-geographic environment interactions.
• The proposed method effectively models geo-features, IoT services, GIS services, and their complex interdependencies.
• The modeling process was illustrated and validated through practical examples.

Conclusions:

• The proposed Petri Nets-based approach provides a robust framework for modeling sensor-geographic environment interactions in ESNs.
• This method facilitates a better understanding and management of performance factors such as response time and fault tolerance.
• The classification of services and the use of service algebra with CPN models offer a comprehensive solution for complex sensor network applications.
