What is esrt in wsn

ESRT stands for Event-to-Sink Reliable Transport in Wireless Sensor Networks. It is a protocol designed to provide reliable communication between sensor nodes and the sink node in a wireless sensor network. ESRT is based on the concept of event-driven communication, where only the relevant data is transmitted to the sink node instead of transmitting all the data collected by the sensor nodes. This reduces the amount of data transmission and conserves energy in the network. ESRT also uses techniques such as data aggregation, compression, and error control to improve the reliability of communication.
