| Summary: | Wireless mesh network (WMN) is one of the topology used in wireless
technology that enhanced the capacity and reduced the maintenance. However,
interference is believed can be one of the factors that reduce the performance of
WMN. Since WMN is using the same channel to communicate with other router, Co
Channel Interference (CCI) was believed to affect WMN performance. Besides that,
Carrier Sensing Interference was also believed to affect WMN performance with the
carrier sensing mechanism such as Carrier Sensing Multiple Access with Collision
Avoidance (CSMA/CA) when two traffic links occurred. Combining the two
interferences, it is interesting to see which of the interference affected the most of the
goodput performance in WMN and which of the effect is dominating by supporting
some facts. The main objective is to investigate whether CSI or CCI is more
dominate if both interferences occur at the same time in WMN. In this thesis, the
experimental test was carried by setting up the test-bed of 16 different cases of
interference to analyze the goodput of WMN. The result finding showed that in
different protocols has different interference dominate. In the end of this thesis
conclude that different protocols have different interference that need to be tackled. |
