| I have a question for clarification. Could you explain in detail the relation between Fig.2 and Fig.3? In Fig.2, are the area except access points in the floor obstacles explained in Fig.3? |
Figure 2 explain floor plan with the position of access point. Figure 3 is approximation of the floor plan without access point but the obstracles in figure 3 is the rooms that in the middle of the building. |

| What will happen when signal to noise ratio is low? |
If signal to noise ratio is low, the positioning performance of K-Nearest Neighbour algorithms will be low accurate as well. From the research, we discover that the low signal to noise ratio can be improved by changing the wifi channel to the channel that has less noise. |

| Why is your limitation of your algorithm? |
Algorithm that be used can localise the object but cannot know the size of the object. When it is working with D-star algorithm, path can be trouble for the shape of the object such as car or UAV and the shape of the area. |

| Thank you for your presentation. Do you have any comparative evaluation results? |
Since the objective of this research is to present new method that combined K-Nearest Neighbour algorithms and d-star algorithm to localise and plan indoor path. So, there is not this kind of research to compare with other mathod. |

| Could you please tell me how to solve the problem of RSSI volatility when the WiFi signal passes through the building in the indoor environment? |
We select the wifi channel that has small number of user and has been checked that the recieved signal came from the correct access point. |
