Saw Index — Popular & Reliable

In cognitive radio networks, Secondary Users (SUs) must decide when to hand off or switch spectrum channels based on criteria like bandwidth availability, path loss, and network jitter. Algorithms calculate the SAW index to yield ultra-fast, automated routing decisions to maintain high Quality of Service (QoS). ⚖️ Strengths and Limitations

Each normalized score is multiplied by its relative assigned importance weight ( ), where the sum of all weights must equal 1 ( ). The final SAW index ( Vicap V sub i ) for an alternative is formulated as: saw index

The mathematical structure of a SAW Index relies on a weighted linear combination of normalized values. For any given alternative , the index value ( Vicap V sub i ) is calculated as follows: In cognitive radio networks, Secondary Users (SUs) must
