摘要/Abstract

摘要： ETX(Expected Transmission Count)是现有的低功耗有损网络路由协议(Routing Protocol for Low power and Lossy Networks,RPL)采用的一种路由度量。ETX最小化了两个节点间成功传输一个数据包所需发送的次数,但在数据传输的实时性方面的考虑有所欠缺。在ETX的基础上最小化数据传输延时,保证数据传输的高成功率和低延时,最后在contikiOS中实现并与标准的ETX进行了比较。

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
