It can be supported with minimal hardware and software changes depending on the application. However, Wi-SUN also has problem as bottleneck, which can be solved by limiting the number of child nodes of a parent node using the N_max method. This method has additional problems with orphan nodes. To solve these issues, this paper proposes a method that provides connectivity to prevent orphan nodes and solves congestion. The proposed method is evaluated for performance using Network Simulator 3(NS-3)." }
