Improvement of ETX Metric Base on OLSR

摘要：

This paper analyzes the problems in the wireless network caused by using minimum hop count as its routing metric, and discusses ETX metric which invented by De Couto to solve these problems and the shortage of it in mobile environment, then modifies it by relatively counting as to make it suitable for such environment. This paper uses the new ETX as a metric for the OLSR routing protocol, and proves that its capability parameters, like throughput and average packet retransmission count etc, are better than ETX proposed by De Couto in mobile environment by software simulation.
