Abstract: ETX (Expected Transmission Count) is routing metric of existing RPL(Routing Protocol for Low power and Lossy Networks).ETX minimizes required total number of delivering a packet between two nodes successfully.Howe-ver,it does not take the real-time data transmission into account.This paper minimized the latency of data transmission based on ETX,and guaranteed high success rate and low latency of data transmission.Finally,the improved algorithm was implemented in contiki OS and compared with the standard ETX.

Key words: WSN,ETX,RPL,Routing metric
