<p>Most of the applications in real world is connected through internet or intranet through a well-supported network layer. The data captured through physical layer traverses through nodes in network layer. During this process the QoS must be maintained effectively for optimized point to point or multipoint communication. The nodes are connected, in order to maintain the connectivity and chose an efficient path nodes are clustered and Cluster Head are assigned to monitor the QoS of the network layer. In this research work the Static type of network is considered, its quality is enhanced in terms of attributes such as energy efficiency, network lifetime, etc., the nodes are used for routing packets, the clusters are formed in circular regions and transmission and reception paths are established. In this work C-LEACH which is the standard WSN algorithm is improved by adapting Circular Clustering (CC) before forming a Cluster Head, the algorithm improves the QoS of the WSN.</p>
