Optimal Number of MOAP Robots for WMNs Using Silhouette Theory.

Recently, various communication technologies have been developed in order to satisfy the requirements of many users. Especially, mobile communication technology continues to develop rapidly and Wireless Mesh Networks (WMNs) are attracting attention from many researchers in order to provide cost efficient broadband wireless connectivity. The main issue of WMNs is to improve network connectivity and stability in terms of user coverage. In our previous work, we presented Moving Omnidirectional Access Point (MOAP) robot. The MOAP robot should move omnidirectionaly in the real space to provide a good communication and stability for WMNs. For this reason, we need to find optimal number of MOAP robots. In this paper, we use silhouette theory to decide the optimal number of MOAP robots for WMNs in order to achieve a good communication environment.
