AB  - Wi-SUN is a future technology that is gaining popularity to meet the demand for wireless networks such as smart grids and smart cities. 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).
