Recent years, wireless network is a very hot topic. Using multiple paths is one way to improve the performance of routing protocols by addressing the problems of scalability, security, lifetime of network and instability of wireless transmission. MP-OLSR is one of the multipath routing protocols. In this report, we do a further analysis in it based on 2 other criteria (background traffic and node density) except mobility. Meanwhile, there is a hot debate on whether ETX is a better link metric than hop count. Thus an implementation of ETX in MP-OLSR is also shown in details here. Then the comparison between these 2 metrics on QoS is taken place. In our experiment, both ETX and hop count have their strength and weakness. As we will see, it is not necessarily to conclude that ETX can improve MP-OLSR. In this report, a brief introduction of background knowledge is in the first part, followed with the objectives of our project. Then is the main part of state of art, including OLSR, MP-OLSR, hop count and ETX. The way to implement ETX in MP-OLSR in details is then following in chapter 3. What are next are the experiment results and the analysis, including comparison between OLSRv2 and MP-OLSR, ETX and hop count in QoS. Finally come our conclusion and future works suggestions.
