An Energy Efficient FCM and CAT Swarm Optimization based Data Gathering in WSN

The collection of information from sensor nodes (SN) used for transmitting the data towards the sink node is said to be data aggregation. In data aggregation the nearest node will receives the information about the nodes which send information to the sink. From now, the sink overloaded and energy loss will occur because of loss of information. In this paper Fuzzy C-Means (FCM) based technique is used for selecting the rendezvous points (RP). Now the main intention is to transmit the nodes/points based on the weightage. Here, the nodes with uppermost weight of RP is selected and transmitted. The outstanding RP were utilized by preserving energy. Finally, CAT swarm optimization (CSO) is used for optimal path selection of mobile sink. The proposed methodology is implemented in the working platform of NS2 and the results were evaluated by using Network lifetime, delay and delivery ratio metrics.
