Illustration of Vertical Handoff Operation with Code Implementation

This program has been developed to illustrate the concept of vertical handoff operation, which involves transferring a mobile device's active connection between different network types (e.g., from Wi-Fi to cellular networks). The implementation includes real-time signal strength monitoring algorithms and handoff triggering mechanisms based on predefined threshold values. Key functions simulate network scanning, connection quality assessment, and seamless transition protocols to minimize service interruption. This demonstration is particularly relevant when users move between coverage areas where different networks offer varying levels of reliability and performance. The program provides detailed analysis of vertical handoff benefits (improved connectivity, load balancing) and drawbacks (potential latency, packet loss), incorporating logging mechanisms to track handoff decision processes. Users can modify threshold parameters in the code to observe how different handoff strategies affect connection stability and quality of service metrics.
