The packet loss rate is the percentage of packets that are sent over a network but do not arrive at their destination. High packet loss rates can significantly affect the performance and reliability of data transmission, resulting in delays, decreased throughput, and poor quality of service. It serves as an essential metric for assessing network health, especially in wireless sensor networks where transmission power control plays a vital role in optimizing communication.
congrats on reading the definition of packet loss rate. now let's actually learn it.
